Cabinet Compartments The RTC 4150 is divided into several main compartments, as shown in Figure 6:

• Equipment compartment

• Splice bay

• Battery base

• Optional cross-connect bay

Equipment Compartment The equipment compartment houses the DC power subsystem, the active electronic gear subscriber fiber management, alarm panel, specials equipment, and also contains space for future expansion. Located at the top of the equipment chamber is the internal equipment air circulation system. This environmentally controlled cooling system draws air up through the electronics and pushes this air down the door through the inside air loop of the door mounted heat exchanger.

Located below the fan assembly is the Valere DC distribution shelf. The unit is configurable to support up to three 30Amp rectifiers OPN 650132). Two are shipped with the base cabinet configuration. The Valere unit is configured with a BC1000 intelligent Ethernet controller and a low voltage battery disconnect (OPN 650400).

Figure 5: Equipment Compartment

The Fuse and Alarm Interface Panel is located in the electronics compartment and is equipped with plug-in, alarm-indicating fuses for distribution of –48 V DC power to the cabinet fans and to control circuitry. The fused circuits power additional cabinet equipment.

Battery Compartment The battery compartment is located directly below the equipment compartment and is available in single or dual battery strings. It supports multiple 48 V DC strings of batteries for backup power. A thermostatically-controlled, AC-powered battery heater protects the batteries from reduced capacity due to cold temperatures, and battery temperature probes for monitoring battery temperature. The battery compartment dimensions are 34.4”W x 18.0”D x 11.0” H with out earth quake restrains. Approximately ½ inch in height and ¾ inch in width is lost when you install earth quake restraint brackets.

Battery Heaters

The battery heaters are located beneath the plate on which the batteries rest. They are designed to prevent the loss of battery reserve capacity that occurs when batteries are exposed to cold temperatures. The heater is connected to a thermostat that is set to operate the heater pad when it senses battery temperatures below 32°F ±5°F (0°C ±3°C). The thermostat shuts off the heaters when it senses above 50°C ±5°F (10°C ±3°C).

Battery cooling is provided by the heat exchangers within the base cabinet configuration. The heat exchangers draw air through vents into a baffle located at the top of the splice bay and exhaust the air into the heat exchanger plenum. Outside air, drawn past the batteries by the heat exchanger, reduces the heating of the batteries that occurs as a result of solar heating of the battery

compartment sides, by the equipment heat in the cabinet, and self-heating due to charging.

The resulting reduction in battery temperature extends the life of batteries.

Security

The electronics and side compartment doors are accessed using the special hex key (OPN 650145 or Fluke Networks can wrench insert, part # 44007000) and can be padlocked, when required. The battery panel and cable entrance panel can only be removed by first opening the electronics compartment door and side compartment door, respectively.

Fuse and Alarm Interface Panel The Fuse and Alarm Interface Panel (MAIP) is located on the right side of the electronics compartment in the RTC 4150 unit. It is equipped with plug-in, alarm-indicating fuses for distribution of -48V DC power to the cabinet fans and control circuitry on the MAIP. The fused circuits are used to power other cabinet equipment. The table below illustrates these circuits and their positions. Figure 6 displays a circuit diagram for the MAIP.

The Valere rectifiers, batteries, and load fuses are connected to a common bus, so that the batteries start supplying load current whenever required.

Heat Exchanger The RTC 4150 is equipped with a mounted heat exchanger unit. The heat exchanger can be equipped with a thermally-activated, variable-speed fan controller. This controller reduces fan noise and energy consumption during minimal demand thermal periods. An additional noise cancelling baffle option can be configured at the factory to reduce noise further. These measures significantly reduce the fan noise below 65dB to an average performance of 55dB. The RTC 4150 is equipped with a dual loop cooling system. The outer loop vents the battery base as described previously. The inner loop circulates air within the equipment chamber. Both the inner and outer loop fans are thermally activated and do not exchange air.

Fiber Management All versions of the RTC 4150 support the installation of a 144-port fiber patch panel in the equipment chamber under the 6012 chassis. The part numbers that can be installed in this location are shown in the table below.

of-sight portions of private, public, or commercial property with easy access and adequate parking. If you must locate a cabinet near a street or highway, located it away from curves and busy intersections.

• Consult your company’s safe practice guidelines for cabinet site locations.

• Consult company guidelines for cabinet placements regarding rights-of-way and location. Do not locate cabinets in an area that is prone to flooding, next to in-ground sprinkler systems, or where there is constantly damp soil. The cabinet is not intended to be submerged or partially submerged by water, mud, or debris. Adhere to local zoning practices and restrictions prior to pad installation and cabinet placement.

• Avoid the following installation locations: o Small alcoves that enclose the cabinet on 3 or 4 sides o Small alcoves that receive direct sun in the mid to late

afternoon o Hot air exhaust from neighboring buildings or structures o Hot surfaces such as dark asphalt, tarred roofs, or

crushed rock Small alcoves, hot air exhaust, and hot surfaces may cause high-temperature alarms and shutdowns. Small spaces or certain surfaces that receive direct sun light tend to retain the solar energy resulting in a much hotter microclimate installation location. Heat gain within the cabinet has many dependencies such as site loading and traffic, solar thermal loading, geographical location, time of day, weather, cabinet orientation, shading, surroundings, and external air movement. Plan the site to meet or exceed the requirements of local architectural codes, bylaws, or environmental restrictions as applicable.



Safety

Follow all safety guidelines when using pre-cast concrete foundation pads. Pre-cast pads should be in place prior to setting the cabinet. Attempting to place a pre-cast pad over existing cables can result in an unsafe work condition if a person reaches under the pad since the pad is lowered to feed cables through the opening in the pad.

• Only permit operators who are specifically trained and who meet company requirements to operate heavy equipment to place a cabinet.

• All persons working with heavy equipment must wear standard safety headgear, eye protection, and when required, insulated gloves.

• Follow all safe operating practices when using heavy equipment. • Keep bystanders away from all work operations. • Don’t allow operators to suspend loads over people; or permit anybody to

work, stand, or pass under a suspended load.

Pad Mounting Bracket Kit The construction of the concrete foundation pad on site requires the use of a foundation pad mounting bracket kit. However, pre-cast foundation pads, manufactured by concrete fabricators, do not require the mounting bracket kit.

When required, you can order the mounting bracket kit with the cabinet or separately. However, you must order the pad mounting bracket kit in advance of pad construction and cabinet placement. The pad requires several days to cure prior to cabinet placement.

The pad mounting bracket kit, shown in Figure 11, is composed of the bracket, anchors, cabinet mounting screws and washers, and two duct alignment plates. The bracket and inserts become a permanent part of the concrete pad. Use the duct alignment plates to provide the proper location for the cables and ducts, and discard them after the pad is fabricated. The screws hold the anchors and duct alignment plates in place while the pad is being constructed. Discard the screws prior to placing the cabinet on the pad. A new set of screws, shipped with the cabinet, secure the cabinet to the pad.

The pad mounting bracket kit provides:

• A level mounting surface for the cabinet

• The exact location of the anchors for fastening the cabinet to the pad

• The proper location of the telephone cable and AC conduit openings



Figure 11: Pad Mounting Bracket Kit Pad Sizing

The RTC4150 cabinet pad drawing (Figure 12) provides design information for two cabinet foundation pads: the standard pad and the small-footprint pad. The standard pad, which measures 90 inches (2286 mm) by 68 inches (1727 mm), provides walk-around area on all sides for installation, turn-up, and maintenance activities. Also, because the standard pad is a thin slab design, it is the easiest pad version to fabricate. However, if there is insufficient space for the standard pad, the smallest footprint pad that allows the cabinet to be installed in an area as small as 60 inches (1700 mm) by 48 inches (1400 mm) by 6 inches (mm) thick. Both pad versions can be precast and easily transported to the installation site on a standard flatbed truck without the need to stand it up on edge.

Ground Ring Requirements A ground ring, consisting of a solid No. 2 AWG (35 mm2) bare copper wire, must be buried around the perimeter of the concrete mounting pad. The ground ring must be a minimum of 24 inches (609 mm) below grade and within 2 feet (610 mm) of the pad. The ring ground must be bonded, using either an exothermic weld or a listed compression grounding connector, to two 5/8-inch (16mm) diameter by 8 foot (2.4 M) long ground rods. These ground rods must be driven on opposite sides of the mounting pad, and covered with a DLC Flush Mount Ground Rod Closure, as specified in 629-101-901BT, for inspection purposes.

Figure 14: Ground Ring Details

Use the following guidelines for installation when referring to Figure 14: 1. Top of ground rods must be at least 6 inches below grade. 2. Ground rod connections must be made using exothermic welding

(that is, CAD weld) or using a listed compression clamp. 3. As an option, ducts can be provided for the ground wires. Do not use

metallic ducts when multiple cabinets or structures share a common grounding system.

4. The ground system must comply with the National Electrical Code (NEC) and applicable local requirements.

5. Ground rods and ground ring conductors must be spaced apart by at least 6 feet to maintain grounding effectiveness. The ground rods and ground ring conductors can be installed beneath the foundation pad when required.

6. Ground cables from ground ring must be routed into pad conduit.



Easement Size When selecting an installation site, choose a location that has a minimum functional easement large enough to walk around the cabinet with its doors in their fully open and locked position. The table below shows the area required for the cabinets when the doors are opened to their locked positions. The RTC 4150 cabinet doors extend beyond the minimum pad size as shown in Figure 15, which shows the cabinet installed on the foundation pad. Figure 16 illustrates this same arrangement from above, showing clearance distances.

Chapter 3 Cabinet Installation


Chapter 3 Cabinet Installation This chapter describes how to install the RTC 4150 cabinet. NOTE: A substantial portion of cabinet protection against humidity is provided by the normal heat dissipated from the electronic circuits. A desiccant material (on the bottom of each equipment rack) protects the cabinet during shipment and temporary outdoor storage. This material should not be removed until the circuit packs are ready for installation. Power shelf circuit packs should be powered up immediately after installation.

If you cannot put the power shelf immediately (within a few days) into service after installation, activate the bay fans to provide adequate humidity protection. You can also use a low power heat source positioned on each rack, such as an incandescent light bulb, to provide humidity protection. The source should provide approximately 60 watts of heat per day. Once the cabinet is powered up and the fans are operational, remove all desiccant bags.

Unpacking the Cabinet

Use the following steps to unpack the cabinet:

1. Remove the packaging materials to expose the cabinet as mounted on the shipping pallet.

2. Remove the front and slide kick plates to access battery covers accesses the front and rear bolts.

3. Retain the mounting hardware, if needed, for future mounting to the concrete pad.

Installing the Pad Mount Use the following steps to install the pad mount:

1. Prepare cabinet-mounting site as follows. • Dig a trench to locate and stabilize the bottom entry conduit and

ground rod inside conduit entrance holes as shown in the in Figure 14 and Figure 20 (BUX).

• Follow local Telco or NEC requirements for proper system ground rod or ground ring.

• Grade and level the pad site to accommodate the concrete frame.

2. Assemble the concrete forms.

3. Install the gravel base.

4. Arrange the anchor plate inside the concrete form as shown in Figure 13 and Figure 18 (BUX). Use string lines across the form and adjust the anchor plate as necessary with the gravel to level it. Make sure that the



top of the anchor plate is flush with the top of the wooden form. Verify that the ½-13 SS bolts are installed into the holes in the anchor plate to prevent concrete from entering the threads.

5. Pour the concrete level with top of forms keeping the top of the anchor

plate exposed and level with the top of the concrete. Allow a minimum cure time of 24 hours (depending upon environmental conditions) before usage.

6. Broom the finish concrete surface and chamfer all concrete edges.

7. Use shims to adjust the cabinet, so that the cabinet door is true. If the

pad is crooked, the cabinet doors will be crooked.

Routing Conduit and Cable The RTC 4150 cabinet was engineered with the following design considerations:

• AC wiring is routed into the AC panel through a 3” conduit on the side of the equipment bay. There is a 3” knock out on the bottom of the AC/Meter/GenCon unit. The cabinet has brackets that allow a 3” O.D. conduit to be secured to the exterior of the cabinet.

• Subscriber and transport fiber cable, as well as subscriber copper cabling, is routed through the conduct access holes on the bottom of the splice bay.

• The main cabinet ground is located at the bottom of the splice bay.

Note: Use a non-armored OSP distribution fiber when using a splice / termination fiber management system. Armored OSP fiber is not supported in the cabinet.

The table below shows the recommended locations for cable entrance into the cabinet. Follow these recommendations to limit any difficulties on site during cabinet placement and cable routing. Note that the large boots have a maximum diameter of four (4) inches.

Cabinet Type OSP Cables Fiber Cables AC Wires RTC 4150 Splice compartment – 2

Large Boots on the right. Splice compartment – Single large boot on the left.

Outside the cabinet frame on the right side. Install conduit for AC wires on site.

To place and route cable into the cabinet, use the following steps: Note: If cables have not yet been installed, proceed to step 7. 1. If cables have already been installed in the ground, open the side

compartment door using the special hex key. 2. Open the door until the shoulder slides into the slot at the end of the bar

and secures the wind latch.



3. Loosen the screws that secure the splice chamber cover, remove it, and store it in a safe location.

4. Remove the orange plugs and/or the D-shaped grommets located at the

bottom of the splice chamber. 5. Peel away the gasket from the seam near the center of the lower flange

up to the right and left ends of that flange. 6. Remove the lower gasket flange and kickplate, using a screwdriver or 10

mm socket. The removal of the sheet metal allows the cabinet to slide over the cables.

7. Make sure the boom line is taut. Open the cabinet’s front dour using the

special hex key. 8. Verify that the doors are opened to their locked position. 9. Use a screwdriver or 10 mm socket to remove the screws that secure each

battery compartment panel. 10. Tilt the top of the panel outwards and then lift it to remove the panel, as

shown in Figure 17.

Figure 17: Lower Gasket Flange and Kickplate Removal 11. Remove the four bolts that hold the cabinet to the pallet from the

corners of the battery compartment.



Shimming the 4150 Cabinet After the RTC 4150 cabinet is resting on the concrete pad, use the following steps to shim it. Level: 1. Secure the cabinet to the pad with the screws, washers, and rubber

washers provided in the cabinet installation kit, as shown in Figure 18. For precast pads with ½-13 threaded inserts, use the 1½ inch (38 mm) long screws and the ½ inch (12 mm) washers supplied with the cabinet installation kit.

Figure 18: Securing the Cabinet to the Foundation Pad

2. Tighten the mounting fasteners and check the clearances above the front door as shown in Figure 19.



Figure 19: Shimming the Cabinet 3. If the difference between Gap A and Gap B is greater than 1/16 inch (1.5

mm), loosen the mounting fasteners and install shims as shown in Figure 19. The shims are included in the cabinet installation kit.

4. Retighten the mounting fasteners and check the door clearance again. 5. Verify that all doors open and close freely. 6. Remove the clevis from each lifting eye or mounting bracket of the

cabinet. 7. Move the slings and boom line away from cabinet. 8. Remove the lifting brackets from the top of cabinet by removing the

hex-head bolts. Replace all hex-head bolts previously removed.

Sealing OSP Cables Note: Option A shows a single 900 pair OSP cable (Figure 20) and Option B shows

two 600-pair OSP cables installed (Figure 21).

To seal around the outside plant cables and the side compartment, use the following steps:

1. Use cable ties to temporarily secure the copper and fiber cables in the



side compartment, Figure 20 (Option A) or Figure 31 (Option B). Note: Be careful not to violate the cable’s minimum bend radius requirement.

With Option A (Figure 20), position the copper cable in the right-most cable port, and position the fiber cable in the left-most large cable port. In both cases, insert the two ground cables through the round grommet located between the two large cable ports (Figure 22).

Figure 20: Option A for 4150 Cabinet with Cables Installed (prior to splicing)



Figure 21: Option B for 4150 Cabinet with Cables Installed (prior to splicing)

Figure 22: Cable Entrance Ports with Cable Seals and Grommets Installed



2. Reinstall the lower gasket flange using a screwdriver or 10 mm socket.

3. Reinstall the gasket around the lower gasket flange so that the two ends meet near the middle with no gap between them as shown in Figure 23.

Figure 23: Reinstalling the Side Compartment Door Gasket Note: The door gasket is stretchable. If the gap requires adjustment, remove the

gasket from the bottom flange and either stretch or compress it along the side flanges.

Caution: If you stretch or compress the gasket along the bottom flange, the gasket will either shrink (which increases the gap) or slide off the flange.

4. Reinstall the D-shaped grommets into the cable entrance plate. Use a

knife to slice the grommet to allow it to be installed around the fiber cable.

5. Locate the cable seal kit packed in a cardboard box in the battery

compartment. This kit contains the following items:

• 3 Cable seals • 12 Cable seal washers • 14 M6 hex nuts • 3 Large hose clamps • 3 6 AWG (16 mm2) bond strap • 1 Instruction sheet • 1 Small hose clamp



6. Install the cable seals over the copper cables as follows:

a. Measure the cable diameter and trim the cable seal (leave the cable diameter mark on the seal) (Figure 24).

b. Slide the cable seal over the cable such that the smaller diameter of the seal goes over the cable first and ends up facing down when slid into place. If the cable is already connected, you can split the cable seal to allow installation.

c. To split the cable seal, use a knife to cut between the channels on the outside of the cable seal. The maximum diameter cable allowable is 3-3/8 inch (85 mm).

d. Position the cable seal to fit into the notch in the cable entrance plate.

Figure 24: Trimming the Cable Seals

7. After you slide the cable seal into position, use the four cable seal washers and four M6 nuts to secure each cable seal to the lower gasket flange panel (refer to Figure 25).

8. Use cable ties to close the cable seal if it was split. Attach a hose clamp

around the small end of cable seal and tighten it onto cable (Figure 25). Use the small hose clamp for cables with diameters less than 1-1/2 inches (38 mm). Also, secure cable seals over any unused cable ports.

9. Caulk any gaps between the cables and the cable seal. (This step is

particularly important if more than one cable is installed in a single cable seal.)



10. Seal around the entire lower gasket flange panel and all grommets using silicone sealant or suitable caulk, ensuring a watertight seal. Refer to Figure 25.

11. Reinstall the kickplate using two M6 screws.

CAUTION: Ensure that all gaps at the bottom of the side compartment are completely sealed. Gaps allow moisture, insects, and other contaminants to enter the cabinet, causing condensation and equipment damage.

Figure 25: Installing the Cable Seals

12. Caulk around the top of the cable ducts with duct plug compound to seal clearances between the cables and the ducts. Also, seal all duct openings without cables (refer to Figure 26 or 27.)



Figure 26: Side Compartment with Cables Installed (Option A)

Figure 27: Side compartment with Cables Installed (Option B)

Installing the Battery

Battery installation and maintenance must be done by qualified personnel due to potential exposure to harmful DC voltages and chemicals if batteries are



misconnected or damaged. Always disconnect the batteries (Quick-Connects or breakers) when working on them. In addition, give careful attention to a proper battery polarity connection. Failure to connect batteries correctly could result in injury to personnel from arcing and damage to the DC rectifiers and any connected equipment that may void its warranty Batteries are extremely heavy. Use extreme caution when handling and installing them.

Use the following steps to install the batteries:

1. Begin this procedure after the cabinet has been securely mounted in place.

Make sure the Battery Breaker of the AC Panel is in the OFF position.

2. At initial installation, remove the rectifiers (packaged in boxes) located in

the battery compartment and store them in a safe location before populating them in the DC Power Plant.

3. Move the battery cables/temperature sensors out of the way during battery installation. The batteries should be placed so there is ~ a ½" gap between them (there should be 4 to a row).

4. The battery cables come pre-crimped with a lug to connect to the Batt1(-) and Batt4(+) terminals of the battery string. (Refer to Figure 28.) For safety, they have insulating heat-shrink over the metal lugs. For each battery string to be installed ONLY, strip off the insulation covering the metallic lug on the battery cables.

5. Once the lugs are exposed, connect the cable labeled "Str1 +" to the Batt4(+) terminal.

6. Connect the cable labeled "Str1 -" and the Battery Temperature Compensation probe (with ring terminal) to the Batt1(-) terminal.

7. Connect battery cables to batteries (Batt1[-] and Batt4[+] for String 1) before any intercell connectors are installed

8. Connect the intercell connectors (Batt1[+] to Batt2[-], Batt2[+] to Batt3[-], Batt3[+] to Batt4[-]).

NOTE: When the last intercell connector is attached, there may be a slight spark. This is normal operation.

9. When all batteries are installed, complete the circuit to the DC Plant, plug in the Quick-Connects or turn the Battery Breakers ON.

Grounding The cabinet grounding system consists of a cabinet equipment bay ground and a main ground bar located in the bottom of the splice bay. Refer to NEC Codes, local building and safety codes, and company grounding guidelines to construct the ground field.

Fiber Routing Instructions for All Fiber Configuration Use the following steps for routing all fiber configurations: 1) Route the pre-terminated fiber management panel tails through the

bottom of the splice bay. Route the blunt end of the fiber management tail out to the splice point. Follow company best practices for the slack loop length. Be sure there is a workable amount of OSP cable in the splice bay to allow the installation of the fiber panel. Do not include an OSP slack loop inside the splice bay because it will prevent the installation of all 6 panels per rail.

2) Mount the fiber management panel at the top-most position on the rails

in the splice bay. A top-most installation allows for easier installation of panels added in the future.

3) Secure the OSP cable within the splice bay with the fiber bracket

supplied with the fiber management panel. The hole pattern within the right rail is intended to attach these cable anchors.

4) After you have installed the fiber management panel and the OSP cable,

the panel should open when your turn the ¼ turn anchor screw. It should swing freely without the OSP cable binding. This door swing feature allows for future serviceability capability.



5) For subsequent panel installation the panels, mount them immediately below the upper panel. Follow the panel and OSP anchor instructions referenced in Steps 1-4. Install the 2nd panel immediately under the top most panel. No gap is required.

6) Each Fiber management panel has been out fitted with a pem stud on the

top and bottom of the left-rear side of the fiber management panel. This pem stud has been included to allow the panels to be tied together to swing as one panel for servicing. When the ¼ turn anchor screws are in the free position, multiple panels can rotate to the open position for servicing. The panels, when tied together, should swing freely without the OSP cables causing any binding or tension.

Figure 29: Pem Stud Location

Note: Use caution when opening this fiber management panel since all fibers on the rear of the fiber management panel are 900 microns and can be damaged.

7) After the panel(s) have been installed and tested, remove the record

locator panel sticker and place it on the inside door of the splice bay door. When the splice bay door is opened, the record locator panel sticker should be lined up to allow for easy to reference record keeping.

8) Fiber color assignments: The panels are numbered in 6 rows of 24 ports

each. Buffer tube and fiber number assignments follow industry guidelines and are described in the table below.

9) Fiber panel routing: The panels have been outfitted with right and

center guidance pins for fiber management. Jumper fibers can be routed as shown in Figure 29. This fiber routing recommendation allows for the fibers on the right side to be serviced without disturbing the fibers to the left of the affect fiber. Dress the fibers in the panels using Velcro straps.

10) Each fiber panel has been equipped with a Velcro loop on the right side

to secure the jumper fibers exiting the panel, as shown in Figure 30. Fiber jumpers exit the panel from left to right through the fiber pins and down. A rubber fiber stop is supplied for the pins on the right side of the panel to prevent the fibers from shifting forward.

Figure 30: Anchor Loop Location

11) All fiber jumpers are routed down the splice bay to exit the cabinet, as

shown in Figure 31. There is fiber guide with a Velcro strap located at the bottom of the splice bay. This fiber guide routes the fibers into the bottom of the equipment bay.



Figure 31: Routing of Fiber Jumpers

12) Equipment bay fiber routing. The equipment bay is equipped with slack

management along the inside wall of the cabinet and across the rail of the cabinet. Fibers are routed from the bottom of the equipment bay up the side wall and then across the bottom of the horizontal management tray before being routed up to the blade. Figure 32 shows a photograph of the fiber routing. Use the split tube provided in the cabinet to guide the fiber from the tie down point at the bottom of the cabinet (5) to the top of the chassis (6). For shorter lengths use the slack loops provided



Figure 32: Fiber Routing in Chassis

13) Rear Equipment bay fiber routing. The rear equipment bay is equipped with a horizontal slack management across the rail of the cabinet. Fibers are routed from the bottom of the equipment bay and across the bottom of the horizontal management tray before being routed up to the blade. Figure 33 shows a photograph of the fiber routing. Follow the routing path points 1-5 to route the fibers. Use a split tube, supplied in the cabinet, to protect the fibers from points 3-4. Fiber blades in slots 7-12 will have a shorter length. For these shorter length fiber jumpers an extra loop as described in steps 3’ and 5’.



Figure 33: Fiber Routing in Chassis

14) Use the split tube provided in the cabinet to guide the fiber from the tie

down point at the bottom of the cabinet (5) to the top of the chassis (6). For shorter lengths use the slack loops provided.

Appendix A Cabinet Maintenance


Appendix A Cabinet Maintenance A number of cabinet components (fans, batteries, heater pads, and so on.) have life expectancies that are shorter than the cabinet structure and wiring. These components may need periodic inspection or replacement for continued trouble-free system operation. This appendix provides the procedures for performing a routine inspection of the RTC 4150 cabinet. These procedures do not include the inspection or maintenance required by the battery plant; for these procedures, refer to the manufacturer's service manual for the particular type of battery used in the cabinet. Occam Networks recommends that the maintenance procedures described in this appendix be coordinated with battery maintenance. Have only a trained and qualified technician perform all service. Perform the maintenance activities as indicated in this appendix. Review all safety instructions and precautions before attempting to service or repair the cabinet or any components.

Routine Inspection Use this procedure to perform a routine inspection of the cabinet and specified components. This procedure should be done whenever the cabinet is visited and at least every 6 months. Service the components more often if operating in extremely dusty or dirty conditions. Some steps do not apply to all cabinets. Check Battery Compartment/Heat Exchanger Air Inlets Use the following steps to check the battery compartment/heat exchanger air inlets.

1. Inspect the battery compartment (heat exchanger) air inlets to ensure they are clear of debris and clean them if necessary. The right air inlet is located on the cabinet door interior near the bottom. The left air inlet is located on the opposite side of the battery compartment;

2. Open the side compartment door to view. The overall cabinet inlet is at the top of the splice door. Inspect and clean it if needed. The cabinet does not have any filters to be cleaned or changed.

3. Ensure the area near the air inlets is clear of debris that could possibly clog the inlets. Check Surge Arrester Use the following steps to check the surge arrester.

1. Open the door that allows access to the AC power panel. The surge arrester is located behind the main dead front of the external power pedestal.

2. Verify that the indicator LED is lit. 3. If the indicator is not lit, have a qualified electrician replace the surge arrester.

Check GFCI Outlet Use the following steps to check the GFCI outlet.

1. Locate the ground fault circuit interrupt (GFCI) outlet on the right side of the AC power panel.

1. Test the outlet according to the instructions on the AC power panel label. 2. If the GFCI outlet fails, have a qualified electrician replace the outlet.



Inspect Cabinet Mounting Bracket Use the following steps to inspect the cabinet mounting bracket.

1. For cabinets mounted on a pole-mount, or with an H-frame/wall-mount bracket, inspect the bracket for rust or damage.

2. Pay particular attention to the four inserts in the rear side of the cabinet. 3. If required, touch-up or repair it as necessary.

Cabinet Fan Replacement Because the fans used in the cabinet are a wear item, the standard maintenance procedure for fans is to replace the fan unit assembly when a fan alarm is reported. Occam Networks does not recommended that an individual fan motor be replaced. All cabinet fans exceed the Bellcore required minimum 40,000-hour L10 life rating (90% of fans operating satisfactorily after this time period, approximately 5 years).

Replacing Bay Fans Use the following steps to replace the cabinet fan.

1. Locate the bay fan unit at the top of the rack in the electronics compartment, directly above the DC Power System.

1. Using a screwdriver or a 10mm socket wrench, remove the two screws on the front of the fan unit.

5. Use a Phillips screwdriver to remove the fan from its bracket, and install the new fan on the fan-mounting bracket.

6. Reattach the fan-mounting bracket to the door with the following steps:

a. Position the fan bracket assembly on the door. b. Insert a lock washer onto an M6 screw. Use a 10 mm nut driver to thread and

tighten the screw into each nut of the threaded mounting holes.

7. Route the fan cable through the grommet on the fan bracket.

8. Route the heat exchanger fan cable assembly cables through the grommet on the electronics compartment floor that is used for route through.

9. Connect the fan assembly cables to the MAIP bracket per the markings on the connectors.

10. Properly dress the cable and secure it with cable ties. Ensure that the door can open and

close completely without damaging the fan cables.

11. Apply silicone to the electronics compartment grommet hole that the heat exchanger fan cables were routed through.

12. Check for airflow at the front of the fan to ensure that the fans are functioning.

13. Check to ensure that no fan or fuse alarms are active.

Battery Replacement

Placing the DC power system battery switches in the OFF position does not provide complete protection for working on the batteries. Follow standard safety procedures when inspecting batteries.

Periodic monitoring of battery condition is necessary to ensure sufficient reserve capacity in an emergency situation. Occam Networks recommends that the battery plant in a cabinet be checked for individual battery condition and capacity every twelve months.



Replace batteries only as full strings when maintenance indicates that an individual battery or the string it is in does not meet its manufacturer’s recommended requirements for open cell voltage or charge holding capacity.
