3 CMMmicro FEATURESThe Cluster Management Module micro (CMMmicro, Part 1070CK) provides power, GPStiming, and networking connections for an AP cluster. It is configurable through a webinterface.

The CMMmicro contains an 8-port managed switch that supports Power over Ethernet(PoE) on each port and connects any combination of APs, BHMs, BHSs, or Ethernetfeed. CMMmicro PoE differs fromIEEE Standard 803.3af PoE, and the two should not beintermixed. The CMMmicro can auto-negotiate speed to match inputs that are either100Base-TX or 10Base-T, and either full duplex or half duplex, where the connecteddevice is set to auto-negotiate. Alternatively, these parameters are settable.

A CMMmicro requires only one cable, terminating in an RJ-45 connector, for eachconnected module to distribute

Ethernet signaling.

power to as many as 8 collocated modulesAPs, BHMs, or BHSs. Through abrowser interface to the managed switch, ports can be powered or not.

sync to APs and BHMs. The CMMmicro receives 1-pulse per second timinginformation from Global Positioning System (GPS) satellites through an antenna(included) and passes the timing pulse embedded in the 24-V power to theconnected modules.

GPS status information is available at the CMMmicro in Release 3.0. See Setting theTime Tab of the APon Page 91.

CMMmicro supports the features that are listed in Table 4.

4 UNDERSTANDING SYNCHRONIZATIONThe system uses Time Division Duplexing (TDD) - one channel alternately transmits andreceives - rather than using one channel for transmitting and a second channel forreceiving. To accomplish TDD, the AP must provide sync to its SMs it must keep themin sync. Furthermore, collocated APs must be synced together - an unsynchronized AP

that transmits during the receive cycle of a collocated AP can prevent that second APfrom being able to decode the signals from its SMs. In addition, across a geographicalarea, APs that can hear each other benefit from using a common sync to further reduceself-interference within the network.

4.1 GPS SYNCHRONIZATION

The Navigation Satellite Timing and Ranging (NAVSTAR) Global Positioning System(GPS) uses 24 satellites to relay information for precise derivation of position and time.

The CMMmicro contains a Motorola Oncore GPS Receiver. The CMMmicro is a criticalelement in the operation of the system. At one AP cluster site or throughout an entirewireless system, the CMMmicro provides a GPS timing pulse to each module,

synchronizing the network transmission cycles.

The Oncore GPS Receiver tracks eight or more satellites. The CMMmicro uses the signalfrom at least four of these satellites to generate a one-second interval clock that has arise time of 100 nsec. This clock directly synchronizes APs and BHMs which, in turn,synchronize the SMs and BHSs in the network.

The Oncore GPS Receiver also provides

the latitude and longitude of the GPS antenna (collocated with the CMM)

the number of satellites that are being tracked

the number of satellites that are available

the date

the time in Universal Coordinated Time (UCT)

the altitude of the GPS antenna

other information that can be used to diagnose network problems.

4.2 ALTERNATIVE TO GPS SYNC

A link can operate without GPSsync, but cannot operate without sync. The alternative toGPS sync is to configure the AP or BHM in the link to generate a sync pulse to pass tothe SM or BHS, respectively. Depending on the RF environment in which the linkoperates, this latter alternative may or may not be plausible.

For example, in Figure 1, AP4

is not synchronized with any of the other APs.

is transmitting nearby the other APs while they are expecting to receive SMtransmissions from a maximum distance.


22/108


Release 3.0

22 Issue 1

Figure 1: One unsynchronized AP in cluster

The result is self-interference. In this scenario, the self-interference can be avoided onlyby synchronizing the TDD transmit cycles of all APs that operate in the same frequencyband.

An AP that is isolated by at least 5 miles (8 km) from any other Canopy equipment, or aBHM in an isolated standalone BH link can generate and pass sync pulse without GPStiming and not risk that interference will result from the generated sync. In any other typeof link, sync should be derived from GPS timing.

NOTE:The OFDM Series BHMs generate their own sync. For more information aboutthese modules, see the user guides that support them.

4.3 ADVANTAGE OF GPS SYNC

Although the embedded timing generation capability of the AP and BHM keeps a preciseclock, no trigger exists to start the clock at the same moment in each AP of a cluster. So,the individual AP can synchronize communications between itself and registered SMs,but cannot synchronize itself with other Motorola modules, except by GPS timing (shown

in Figure 2).

5.1.3 Cables

Motorola modules that are currently or recently sold can auto-sense whether the Ethernetcable is wired as straight-through or crossover. Some modules that were sold earliercannot. The MAC address, visible on the module, distinguishes whether the module can.CMMmicro auto-senses the cable scheme.

Where a non auto-sensing module is deployed

a straight-through cable must be used for connection to a network interface card(NIC).

a crossover cable must be used for connection to a hub, switch, or router.

Recommended Ethernet and sync cables can be ordered in lengths up to 328 ft(100 m) from Best-Tronics Manufacturing, Inc. athttp://www.best-tronics.com/motorola.htm. These cables are listed in Table 6andTable 7.

7 RECEIVING SHIPPED COMPONENTSThe best practice is to connect all componentsBHs, APs, GPS antenna, and CMMina test setting and initially configure and verify them before deploying them to aninstallation. In this way, any configuration issues are worked out before going on-site, ona tower, in the weather, where the discovery of configuration issues or marginal hardware

is more problematic and work-flow affecting.

When you receive Motorola products, carefully inspect all shipping boxes for signs ofdamage. If you find damage, immediately notify the transportation company.

As you unpack the equipment, verify that all the components that you ordered havearrived. Save all the packing materials to use later, as you transport the equipment to andfrom installation sites.

8 INSTALLING COMPONENTS

RECOMMENDATION:

Use shieldedcable for all infrastructure connections associated with BHs, APs,and CMMs. The environment that these modules operate in often has significantunknown or varying RF energy. Operator experience consistently indicates thatthe additional cost of shielded cables is more than compensated by predictableoperation and reduced costs for troubleshooting and support.

8.1 OBSERVING INSTALLATION PRECAUTIONS

Use simple precautions to protect staff and equipment. Hazards include exposure to RFwaves, lightning strikes, and power surges. This section specifically recommends actionsto abate these hazards.

8.1.1 Maintaining Exposure Separation Distances

To protect from overexposure to RF energy, install radios so as to provide and maintainthe minimum separation distances shown in Table 11away from all persons.

Table 11: Exposure separation distances

Module TypeMinimum Separation

Distance from Persons

FSK or OFDM radio 20 cm (approx 8 in)

Radio with Reflector Dish 1.5 m (approx 60 in or 5 ft)

Radio with LENS 0.5 m (approx 20 in)

Antenna of connectorized 5.7 GHz AP 30 cm (approx 12 in)

Antenna of connectorized or integrated 900 MHz module 60 cm (24 in)

Indoor 900-MHz SM 10 cm (4 in)

At these and greater separation distances, the power density from the RF field is belowgenerally accepted limits for the general population.

NOTE:These are conservative distances that include compliance margins. In the caseof the reflector, the distance is even more conservative because the equationmodels the reflector as a point source and ignores its physical dimensions.

Limits and guidelines for RF exposure are specified by

US FCC limits for the general population. See the FCC web site athttp://www.fcc.gov, and the policies, guidelines, and requirements in Part 1 of Title 47of the Code of Federal Regulations, as well as the guidelines and suggestions forevaluating compliance in FCC OET Bulletin 65.

8.1.2 Grounding the EquipmentEffective lightning protection diverts lightning current safely to ground, Protective Earth(PE) . It neither attracts nor prevents lightning strikes.

WARNING!Lightning damage is notcovered under the Canopy warranty. Therecommendations in Canopy guides give the installer the knowledge toprotect the installation from the harmful effects of ESD and lightning.These recommendation must be thoroughly and correctly performed.However, complete protection is neither implied or possible.

Grounding Infrastructure Equipment

To protect both your staff and your infrastructure equipment, implement lightningprotection as follows:

Observe all local and national codes that apply to grounding for lightningprotection.

Before you install your modules, perform the following steps:

Engage a grounding professional if you need to do so.

Install lightning arrestors to transport lightning strikes away from equipment.For example, install a lightning rod on a tower leg other than the leg to whichyou mount your module.

Connect your lightning rod to ground. Use a 600SS Surge Suppressor on the Ethernet cable where the cable

enters any structure. (Instructions for installing a Canopy 600SS SurgeSuppressor are provided in the Motorola Point-to-Multipoint (PMP) SolutionsUser Guide.)

Install your modules at least 2 feet (0.6 meters) below the tallest point on thetower, pole, or roof.

Use 10-AWG (6 mm2) Copper Grounding Wire

According to NEC 810-21 3(h), either a 16-AWG copper clad steel wire or a 10-AWGcopper wire may be used. This specification appears to be based on mechanical strengthconsiderations and noton lightning current handling capabilities.

For example, analysis shows that the two wire types are not equivalent when carrying

a lightning surge that has a 1-microsecond rise by 65-microsecond fall:

The 16-AWG copper clad steel wire has a peak fusing current of 35,000 ampsand can carry 21,000 amps peak, at a temperature just below the ignition pointfor paper (454 F or 234 C).

The 10-AWG copper wire has a peak fusing current of 220,000 amps and cancarry 133,000 amps peak, at the same temperature.

Based on the electrical/thermal analysis of these wires, Motorola recommends 10-AWGcopper wire forallgrounding conductors. Although roughly double the cost of 16-AWGcopper clad steel wire, 10-AWG copper wire handles six times the surge current fromlightning.

Shielding is not Grounding

In part, NEC 810-21 states:

A lightning arrester is not required if the lead-in conductors are enclosed in acontinuous metal shield, such as rigid or intermediate metal conduit, electricalmetallic tubing, or any metal raceway or metal-shielded cable that is effectivelygrounded. A lightning discharge will take the path of lower impedance and jumpfrom the lead-in conductors to the metal raceway or shield rather than take thepath through the antenna coil of the receiver.

However, Motorola does not recommend relying on shielded twisted pair cable forlightning protection for the following reasons:

Braid-shielded 10Base-T cable is uncommon, if existent, and may be unsuitableanyway.

At a cost of about two-thirds more than 10-AWG copper UTP, CAT 5100Base-TX foil-shielded twisted pair (FTP) cable provides a 24-AWG drain wire.If this wire melts open during a lightning surge, then the current may follow thetwisted pair into the building.

More than 80 percent of all direct lightning strikes have current that exceeds8,500 amps. A 24-AWG copper wire melts open at 8,500 amps from a surge thathas a 1-microsecond by 70-microsecond waveform. Hence, reliance on 24-AWGdrain wire to comply with the intent of NEC 810-21 is questionable.

Shielded twisted pair cable may be useful for mitigation of interference in somecircumstances, but installing surge suppressors and implementing the groundrecommendations constitute the most effective mitigation against lightning damage.

8.1.3 Protecting Cables and Connections

Cables that move in the wind can be damaged, impart vibrations to the connected device,or both. At installation time, prevent these problems by securing all cables with cable ties,cleats, or PVC tape.

including a drip loop where the cable approach to the CMMmicro is from above.

wrapping the cable with weather-resistant tape.

On a module with an external antenna, use accepted industry practices to wrap theconnector to prevent water ingress. Although the male and female N-type connectorsform a gas-tight seal with each other, the point where the cable enters each connectorcan allow water ingress and eventual corrosion. Wrapping and sealing is critical to long-term reliability of the connection.

Possible sources of material to seal that point include

the antenna manufacturer (material may have been provided in the package withthe antenna).

Universal Electronics (whose web site is http://www.coaxseal.com), who marketsa weather-tight wrap named Coax-Seal.

Perform the following steps to wrap the cable.

Procedure 1: Wrapping the cable

1. Start the wrap on the cable 0.5 to 2 inches (about 1.5 to 5 cm) from theconnection.

2. Wrap the cable to a point 0.5 to 2 inches (about 1.5 to 5 cm) above theconnection.

3. Squeeze the wrap to compress and remove any trapped air.

4. Wrap premium vinyl electrical tape over the first wrap where desired for abrasionresistance or appearance.

5. Tie the cable to minimize sway from wind.

end of procedure

8.2 PREPARING FOR THE INSTALLATIONS

8.2.1 Conforming to Regulations

For all electrical purposes, ensure that your network conforms to applicable country andlocal codes, such as the NEC (National Electrical Code) in the US. If you are uncertain ofcode requirements, engage the services of a licensed electrician.

8.2.2 Standards for Wiring

Motorola modules automatically sense whether the Ethernet cable in a connection iswired as straight-through or crossover. You may use either straight-through or crossovercable to connect a network interface card (NIC), hub, router, or switch to these modules.For a straight-through cable, use the EIA/TIA-568B wire color-code standard on bothends. For a crossover cable, use the EIA/TIA-568B wire color-code standard on one end,and the EIA/TIA-568A wire color-code standard on the other end.

8.2.3 Best Practices for Cabling

The following practices are essential to the reliability and longevity of cabled connections:

Use only shielded cables to resist interference.

For vertical runs, provide cable support and strain relief.

Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermalexpansion and contraction and to facilitate terminating the cable again whenneeded.

Include a drip loop to shed water so that most of the water does not reach theconnector at the device.

Properly crimp all connectors.

Use dielectric grease on all connectors to resist corrosion.

Use only shielded connectors to resist interference and corrosion.

8.2.4 Collocating Canopy Modules

A BH and an AP or AP cluster on the same tower require a CMM. The CMM properlysynchronizes the transmit starttimes of all Canopy modules to prevent interference anddesensing of the modules. At closer distances without sync from a CMM, the framestructures cause self interference.

8.4.5 Installing the Power Supply for the CMMmicro

Install the CMMmicro power converter in only a hut, wiring closet, or weatherized NEMA-approved enclosure. This is imperative to keep moisture away from the power converter,not to shield it from harsh temperatures.

WARNING!Although the output of the power converter is 24 V, the 100-W power ratingclassifies the converter as a Class 2 electric device. For this reason, wheneveryou work on power in the CMMmicro, you must firstdisconnect the DC converterfrom the AC power source.

Perform the following procedure to install the provided power supply.

Procedure 5: Installing the Power Supply for the CMMmicro

1. Connect the 6-ft (2-m) AC power cord to the power converter (but not yet to anAC receptacle).

2. Select the length of power cord as follows:

a. If either mounting the unit inside with the power converter or outside within 9ft (2.8 m) of the power converter, select the 10-ft (3-m) DC power cord (ratedfor outdoor use).

b. If mounting the unit outside and further than 9 ft (2.8 m) from the powerconverter, ensure that this additional length of cord is either UV-resistant orshielded from UV rays.

Use a terminal block, connector, or splice to add the additional length.

Protect the terminal block, connector, or splice (as inside a weatherizedenclosure, for example).

Procedure 6: Verifying CMMmicro connections

1. Access the web-based interface for each AP or BH by openinghttp://, where the is the address of the individualmodule.

2. In the Status page, verify that the time is expressed in GMT.

3. In the menu on the left-hand side of the web page, click on GPS Status.

4. Verify that the AP or BH is seeing and tracking satellites. (To generate the timingpulse, the module must track at least 4 satellites.)

end of procedure

8.5 PASSING SYNC FROM ONE CMM TO ANOTHERFor either of the following cases, you can use the instructions in this section to configurewiring such that one CMM passes its synchronization to another:

Case 1: To use a single GPS antenna (to avoid a second per-antenna sitesurcharge, for example).

Case 2: To set up the fail-over capability to switch to an inactive, redundant,already- synced CMM by remote management.

The CMMs that share sync can be any combination: two CMM4, two CMMmicro, or aCMM4 and a CMMmicro.

Syncing two CMMs requires connecting their RJ-11 auxiliary ports together with a 6-wire

cable and then appropriately configuring each of them. This connection cable is special,not a straight-through cable.

8.5.1 Shared Sync Case 1A single antenna

Connections

The GPS antenna connects to one CMM via coax cable.

The two CMMs connect to each other via a cable that links the auxiliary sync

RJ11 ports of each CMM. Alternatively and depending on network design and other equipment in the

network, the CMMs may connect to each other via an Ethernet cable.

Configurations

In the Configuration CMM tab of the CMM that directly receives sync from theGPS antenna, set the Sync Source parameter to Master (GPS Module).

In the Configuration CMM tab of the CMM that receives sync from the other,set the Sync Source parameter to Slave (RJ11 Port).

Results

Neither the slave CMM nor its connected APs and BHMs displays GPS location

information.

The Master is automatically the server for time-of-day to connected APs andBHMs that specify its IP address as their NTP server.

If a valid, reachable NTP server IP Address entry is present in theConfiguration Time tab of the Slave, then the slave CMM function as an NTP(Network Time Protocol) server. This entry instructs the Slave to

obtain time-of-day from the device at that address.

pass the time-of-day to any connected device that has the IP address of thisSlave configured as its NTP server.

NOTE: This Time tab is present only if the CMM is specified as Slave (as

described above).

8.5.2 Shared Sync Case 2Redundancy

Connections

Each CMM is connected to its own GPS antenna via coaxial cable in thestandard way.

The two CMMs are connected via a 6-wire cable between the RJ-11 auxiliaryports of each CMM.

Depending on network design and other equipment in the network, the twoCMMs may either

be connected to each other via an Ethernet cable.

have separate connections to a router, switch, or other network device.

Configurations

For normal operation, in the Configuration CMM tab of each, set theSync Source parameter to Master (GPS Module).

If one loses sync due to problems with its GPS antenna, coax cable, or GPSmodule, set the Sync Source parameter in the out-of-sync CMM toSlave (RJ11 Port).

Results

In normal (Master) operation

the user interface in each CMM and in connected APs and BHMs displayGPS location information.

each CMM is automatically the server for time-of-day to connected APs and

BHMs that specify its IP address as their NTP server. In fail-over (Slave) operation

neither the CMM nor its connected APs and BHMs displays GPS locationinformation.

if a valid, reachable NTP server IP Address entry is present in theConfiguration Time tab of the Slave, then the slave CMM function as anNTP (Network Time Protocol) server. This entry instructs the Slave to obtaintime-of-day from the device at that address and pass it to any connecteddevice that has the IP address of this Slave configured as its NTP server.

8.5.3 CMM Sync Cable

IMPORTANT!

The pinout of the cable that connects two CMMs for sync differs from thestraight-through sync cable that connects a remote APto an SM, or thatconnects an AP or BHM to a CMM2.

Pinouts for a CMM sync cable and the location of Pin 1, relative to the lock tab on theconnector, are shown inFigure 9.

9.1 MANAGING AND USING THE AUTHENTICATION SETUP

9.1.1 Adding a User

A CMMmicro that has never had a user account configured or one that has been reset tofactory defaults allows access to all of its web page tabs without first requiring a validusername and associated password. This initial access, although not secure, providesthe opportunity for the administrator to configure valid users.

CMMmicro supports four or fewer user accounts, regardless of account levels. The

available levels are

ADMINISTRATOR, who has full read and write permissions. This is the level ofthe root and admin users, as well as any other administrator accounts that one ofthem creates.

INSTALLER, who has permissions identical to those of ADMINISTRATORexcept that the installer cannot add or delete users or change the password ofany other user.

9.1.3 Overriding a Forgotten IP Address or Password

By using an override toggle switch on the CMMmicro circuit board, you can temporarilyoverride the lost or unknown IP address or password as follows:

Up is the override position in which a power cycle causes the CMMmicro to bootwith the default IP address (169.254.1.1) and no password required.

Down is the normal position in which a power cycle causes the CMMmicro toboot with your operator-set IP address and password(s).

you cannot gain browser access to the CMMmicro through anyconnected APs or BHs.

1. Gain physical access to the inside of the CMMmicro enclosure.

2. Establish direct Ethernet connectivity to the CMMmicro (not through an AP orBH).

3. Flip the toggle switch (Figure 12above) up, toward you.

4. Power cycle the CMMmicro.

RESULT: The CMMmicro reboots with the default IP address of 169.254.1.1,password fields blank, and all other configuration values as previously set.

5. Set passwords as desired, or enter a blank space to set no password.

6. Change configuration values if desired.

7. Click the Save Changes button.

8. Flip the toggle switch (see Figure 12 again) down, away from you.

9. Click the Reboot button.

end of procedure

9.1.4 Updating a User

From the factory default state, configure passwords for both the root and admin

account at the ADMINISTRATOR permission level, using the Change User Password tabof the Account web page. (If you configure only one of these, then the other will stillrequire no password for access into it and thus remain a security risk.) If you are intent onconfiguring only one of them, delete the admin account. The root account is the only

account that CNUT uses to update and Prizm uses to manage the CMMmicro.

9.2 CONFIGURING IP ACCESSIBILITY

9.2.1 Fitting IP Access to the Overall IP Scheme of the Network

Network elements are accessed through IP Version 4 (IPv4) addressing.A proper IP addressing method is critical to the operation and security of a network.

Each module requires an IP address on the network. This IP address is for onlymanagement purposes. For security, you should either

assign an unroutable IP address.

assign a routable IP address only if a firewall is present to protect the module.

You will assign IP addresses to computers and network components by eitherstaticordynamicIP addressing. You will also assign the appropriate subnet mask and networkgateway to each module.

Address Resolution Protocol

As previously stated, the MAC address identifies a module in

communications between modules.

the data that modules store about each other.

the data that BAM or Prizm applies to manage authentication and bandwidth.

The IP address is essential for data delivery through a router interface. AddressResolution Protocol (ARP) correlates MAC addresses to IP addresses.

For communications to outside the network segment, ARP reads the network gatewayaddress of the router and translates it into the MAC address of the router. Then thecommunication is sent to MAC address (physical network interface card) of the router.

For each router between the sending module and the destination, this sequence applies.The ARP correlation is stored until the ARP cache times out.

Allocating Subnets

The subnet mask is a 32-bit binary number that filters the IP address. Where a subnetmask contains a bit set to 1, the corresponding bit in the IP address is part of the networkaddress.

Example IP Address and Subnet Mask

In Figure 15, the first 16 bits of the 32-bit IP address identify the network:

Octet 1 Octet 2 Octet 3 Octet 4

IP address 169.254.1.1 10101001 11111110 00000001 00000001

Subnet mask 255.255.0.0 11111111 11111111 00000000 00000000
