Introduction In the few sections below you will be provided with the overall knowledge
about system hardware, NCC specifications and some of the cabinet
components.
______________________________________________________________
NCC and NIDS
Workstations
NIDS is designed to support a distributed database capability, a limited fault
tolerance, and support for redundant common equipment. This ensures
maximum uptime and availability. To ensure that NIDS operates
continuously, the design is optimized to reduce single point of failure
weaknesses. Consequently, NIDS is capable of undergoing some minor
maintenance without disruption to operation of common hardware
(equipment). The workstation must be able to contact a network domain
controller at one of the NCC locations before it can successfully complete a
login to run the NIDS application.
The hardware for a typical NIDS system consists of a NIDS Control Cabinet
(NCC), and NIDS workstations communicating over an Ethernet network.
AT Database Administrator functions can also be performed from any NIDS
workstation by entering the proper user ID and password.
The data from the NIDS database and dynamic data from the various
configured external interfaces are then stored in the memory of the interface
host and distributed to each NIDS workstation and server. The NCC
exchanges data with the workstations via an Ethernet communication link
(Institute of Electrical and Electronics Engineers [IEEE] 802.3U 100
Baseband Twist Pair Cable [Base T]) operating at 10/100/1000 Megabits per
Second (Mbps).

Cabinet Specifications Lesson 4
Hardware Maintenance
Cabinet
Specifications
The NCC (Refer to Figure 4-1) provides for internal mounting of 40 rack-
units of equipment. The rack has exterior dimensions of 24”Wide (W) x
72”High (H) x 30”Deep (D). It has ElectroMagnetic Interference (EMI)
protection, a lockable front and rear door, and is rated for Zone 4 seismic
use. If the NCC is installed in a location which provides for under floor air
cooling, then the fans will not be required. The NCC rack is used at the
TRACON as well as the Air Traffic Control Towers (ATCT). The presence
of an NCC at the ATCT locations is based on the overall system needs as
well as local reliability needs (based on the redundancy the NCC rack
provides).

Grounding and
Shielding
The NCC rack provides two locations to attach FAA-supplied
grounding/bonding straps, near the top and bottom of the rack chassis. Each
location is paint-free and prepared for double bonding bolts in accordance
with FAA-STD-019.
WARNING: Improper grounding of NCC Rack can pose an electrocution
risk to technicians performing installation or maintenance if there is a fault
in the equipment. Additionally, it poses a risk to the performance of the
equipment. Ensure NCC Rack is properly grounded in compliance with
FAA-STD-019.

Hardware Maintenance
Power Source The power source to the NCC is described in the Site Installation Plan and
identifies the circuit size and source. The Site Installation Plan will indicate
whether the supplied power source will be critical, essential, or commercial
power.
______________________________________________________________
Point of Entry Facility power is hardwired to two 20 Amp outlets mounted in the lower rear
of the NCC.
Technicians should be familiar with their facility power distribution and
identify the circuit breakers protecting the NCC equipment. Also, ensure
cables are labeled according to the Site Installation Plan.
______________________________________________________________
NCC Network
Wiring
External network connections to the NCC include workstation computers,
UPSs, the FTI network, and network-based interfaces such as WARP and
VOID. All of these may be connected to any available port on any of the
four NCC Network Switches.
For redundancy, it is recommended that workstations in a single location or
for a single purpose be connected to different switches. For example, if there
are four approach workstation computers at a site, each one should be
connected to a different switch. Likewise, in a room with four workstation
computers (regardless of their roles), each workstation computer should be
connected to a different switch. Spreading the workstation computers across
switches ensures that a single switch failure will not disable an entire room
or an entire job function.

NCC Power
Wiring
The NCC rack has the option of a single AC box (404000) or a dual AC box
(405000) AC connection point. Each single AC box contains two L5-30R
connectors. The dual AC box contains four L5-30R connectors. The UPSs
plug directly into the outlets. The AC box also provides terminals for dual
site AC power connections. External power cables should be routed through
the rack (along the side with all the other power cables) and terminate in the
AC interface box.
Figure 4-4, Dual Single AC Power Boxes Diagram
Prior to performing any wiring activities, ensure the power is shut down,
including de-energization verification, and locked-out/tagged-out in
accordance with FAA Order 3900.19B, Chapter 13, and Hazardous Energy
Control.
______________________________________________________________
NCC Interfaces Network interfaces such as WARP and VOID connect to any available
Network Switch port. All other interfaces are serial-based and connect to the
Interface Splitter Panel (IFSP). When connecting the IRIG-B time server to
the rack, if it is being connected to more than one device, a 600 ohm
termination is recommended.
With the exception of the IRIG-B time server, all remaining network
interfaces are converted in the NCC to RS-232 or RS-485. If the NCC is not
physically configured for a particular interface, the appropriate kit will need
to be installed before external interfaces can be connected.

Time Server Lesson 4
Hardware Maintenance
Description The time server accepts an Inter-Range Instrumentation Group-B (IRIG-B)
serial time code over a RG-58 coax cable from the GPS time source. Then
the Time Server makes the time update available via Network Time Protocol
(NTP) to all network-connected devices over Transmission Control
Protocol/Internet Protocol (TCP/IP). The time server is a Line Replaceable
Unit (LRU) in the event of failure. No specialized skills are required for the
physical replacement of the equipment. Tech Ops must be trained on how to
configure the time server.
The GPS Time Source provides time data in an analog IRIG-B format to
NIDS. This interface is one directional and flows from the GPS time source
to the NIDS Time Server. The Time Server then makes the NTP based time
updates available to all NIDS Clients. The time is displayed on NIDS
software. The NIDS GPS interface Connectivity Point is the Interface
Splitter Panel (IFSP) at a NIDS Control Cabinet (NCC).
The GPS Time Source transmits an analog coded time message to the NIDS
time interface (time server) with standard IRIG-B fields, as specified in IRIG
Standard 200-98. The time server transmits the time data to the NIDS
network using NTP. The old GPS related information is not stored on NIDS.
NOTE: Time Server will be covered in detail in Lesson 6, Network Devices.

Automatic Transfer Switch (ATS) Lesson 4
Hardware Maintenance
Description The NCC houses a single Automatic Transfer Switch (ATS) for management
of the power in the NCC from the UPS units. The ATS houses transient
voltage suppression to protect against voltage spikes and power surges.
The ATS is rack mounted inside the NCC. Indicators on the front panel of
the ATS provide visual indication of the presence of primary and secondary
power sources and indicate which source is selected for use. Observation of
these indicators can show power distribution within the NCC. Since the ATS
is not an Ethernet compatible device there is no representation for the ATS
in NIDS Mon.
The ATS has no serviceable parts and is a LRU in the event of failure. No
specialized skills are required for the physical replacement of the equipment.

Rack Mount UPS Lesson 4
Cabinet Hardware
Introduction The next few sections will familiarize you with most NCC hardware
components and provide you with the knowledge about their maintenance
procedures.
______________________________________________________________
Description For NCC racks, NIDS features the ability to support dual redundant UPS
devices to improve system availability. The rack mount UPS is mounted
inside the NCC. The UPS status is indicated through the front panel
indicators and is also reported in NIDS Mon.
Figure 4-17, Rack Mount UPS
During Normal operation, the On/Off Button and the Mode Indicator
illuminate and the front panel displays the percentage of UPS load capacity
being used by the protected equipment. This is shown on the Load Level
Indicators. The UPS monitors and charges the batteries, providing power
protection to the equipment in the event of a power outage. The main
purpose of the UPS is to provide AC line filtering to protect the facility
critical power system from the harmonics and noise generated from the
cumulative effects of the COTS equipment in the Rack.
During a power outage, the UPS beeps every 5 seconds and the On/Off
Button, Mode Indicator, and Downgraded Operation Indicator are
illuminated. The Battery Charge Level Indicators show the remaining battery
power. When power returns, the UPS reverts to Normal Mode.
When the UPS is turned off and it remains connected to a power source it
goes into Standby Mode. The Battery Charge Level Indicators and Load
Level Indicators are on and all others are off.

LanSafe
LanSafe is power management software running on servers and workstations
providing automatic, unattended and graceful shutdown of computer systems
throughout the network during an extended power failure. It continuously
monitors the UPS status via serial, USB, and network connectivity options.
LanSafe software is running as a background process during normal
computer operation and consists of a suite of applications that contain
the Power Monitor software, Power Scope GUI and the Control Room
Console.
The Power Monitor is a background listener application that allows the
workstation computer to communicate with the UPS. The UPS Console is
the GUI used to view the UPS status, perform minor diagnostics, and view
historical logs.
______________________________________________________________
Power Loss
Should a UPS connected to a server or workstation experience a power loss,
the UPS beeps every 5 seconds, illuminating the battery LED. A counter is
started to monitor the duration of the power interruption.
In the event of a power loss, the UPS is programmed to provide short-term
protection from power interruptions, as well as gracefully shut down the
workstations after three minutes and the UPS itself in six minutes. When
power returns, the UPS reverts to Normal Mode.
After a pre-set time has elapsed without power being restored, the UPS
software initiates a graceful shutdown of the connected computer and
removes power from any connected equipment.
Software running on the UPS then waits a specified time to monitor for
power restoration. If sustained power is restored prior to that time period
elapsing, the UPS will reapply power to the computer and any other
connected equipment.

Considerations
NOTE: If power is removed from the UPS prior to removing power from
the rear outlets, the UPS will detect a facility power failure and operate from
its batteries.

Network Switch Lesson 4
Cabinet Hardware
Description Network switches are installed to connect workstations and devices to the
NIDS LAN. This is the same Network switch used at remote sites and other
locations where a NIDS Network switch is implemented.
The Network switch has no serviceable parts and is a LRU in the event of
failure. No specialized skills are required for the physical replacement of the
equipment. Tech Ops must be trained on how to configure the Network
switch.
The Network switch has four dual-personality ports, which can be used to
connect one switch to another over fiber-optic cable. A mini-GBIC single-
mode or multi-mode module is required and plugs into one of the dual-
personality ports on each of the two switches. Although considerably more
expensive than a CAT6 cable connection, a fiber-optic connection does
provide the ability to connect switches over longer distances at gigabit
speeds. The Multi-mode module supports distances up to 3,000 feet whereas
the Single-mode module can function up to 32,000 feet without degradation.

Power Strips Lesson 4
Cabinet Hardware
Description Two NIDS cabinet power strips receive power from the Automatic Transfer
Switch. All NCC equipment receives power from the two power strips.
The power strips fielded in the NIDS NCCs are the Tripp Lite PDU1215.
Figure 4-22, Cabinet Power Strip
Each power strip provides thirteen 120V outlets protected by a 15A circuit
breaker that is resettable by pressing the Reset button. The outlets are
accessible from the inside of the cabinet. There is a single convenience
outlet provided at the rear of the cabinet. Both power strips receive their
power from the ATS.
NOTE: Power strips and the KVM are the only devices plugged into the
ATS.
The redundant and primary power buses are only related to the UPS’s 1 and
2. The ATS combines this into a single power bus from the primary; if the
primary power dies the ATS switches to the redundant power source. If that
dies the ATS loses power completely. The only devices directly connected to
the primary and redundant power sources are the UPS’s.
Each power strip is grounded to the cabinet’s copper ground bar.

Interface Splitter Panel (IFSP) Lesson 4
Cabinet Hardware
Description The IFSP is only at locations where the interfaces connect to two Serial
Terminal Servers in an NCC. The IFSP will be used as the interface
demarcation point into NIDS. The IFSP provides for splitting the incoming
data signals into two data feeds as well as providing serial surge suppression.
The IFSP is always rack mounted in the back of the NCC.
This unit is mounted on the rear of the NCC Rack and is used to connect the
external weather systems (Interfaces) to the NIDS redundant servers. It
consists of a Power Distribution Unit (401020), which houses and supplies
power to the Interface cards: Serial Splitter (102010), RJ11 Splitter (410000)
and BNC Splitter (107010). The Interface cards support RS232/RS485
serial, RJ11analog and BNC analog (IRIG-B) signals, respectively. External
weather system interfaces connect to the splitter cards using DB9, BNC, and
Registered Jack 11 (RJ11) connectors as appropriate.
The Serial Splitter card has two RJ45 ports which are connected to the
primary and secondary Serial Terminal Servers using CAT6 cables. The
RJ11 Splitter card receives the DASI (DASI signal is split), Wind Measuring
Equipment (WME) or modem analog signal and outputs it to the respective
device mounted inside the NCC rack at which point it is converted to an
RS232 signal and carried via serial cables to the STSs. The BNC Splitter
card receives the IRIG-B signal from the GPS device and sends it to the
Time Server mounted inside the NCC rack and if necessary, splits the signal
and forwards it to another Time Server.
______________________________________________________________
IFSP – Power
Distribution Unit
Remove and
Replace
The Power Distribution Unit is base component of the IFSP. The Power
Distribution Unit is a rack mount card cage that can hold up to twelve cards.

Serial Terminal Server Lesson 4
Cabinet Hardware
Description In the NCC the STS units are installed in pairs in a NCC rack to facilitate the
Primary Host / Secondary Host automatic failover protection for weather
systems interfaces. The STS is also used at locations that do not have an
NCC as a method of providing a standardized approach for bringing external
data interfaces into NIDS. The STS is always used with either an IFP or
IFSP. External data is never directly connected to the STS without going
through a NIDS demarcation panel with surge suppression.
Serial Terminal Servers are mounted inside the hinged rear door of the NCC,
providing easy access to these components and connections. They are rack
mounted and accessible for interface connections. Serial Terminal Servers
are not limited to the NCC. They can also be used with workstations.
A Serial Terminal Server has no serviceable parts and is a LRU in the event
of failure. No specialized skills are required for the physical replacement of
the equipment.
Serial Terminal Servers will be covered in greater detail in Lesson 6,
Network Devices.

Cabinet Hardware
Preventive
Maintenance
Racks installed in locations that don’t supply chilled air through the floor
will have rack front doors with an air filter. The filter should be removed and
cleaned with a vacuum cleaner, compressed air, or with water. When using
compressed air, carefully direct the air flow so it is not blowing directly on
the component. If water is used, dry the filter completely before replacing it
in the rack.
Racks installed in locations with EMI reduction requirements will have a
rack top EMI filter. This filter blocks radio signals but allows air to pass
through. The EMI filter may collect dust. The dust may be removed with a
vacuum cleaner, compressed air, or by brushing (with a paintbrush or similar
soft brush). When using compressed air, carefully direct the air flow so it is
not blowing directly on the component. The filter may be removed by
sliding it up out of the slots that hold it in place. Pull the top of the filter
away from the door while lifting. Replace the filter by reversing the process.
