Redeploying Modules Growing Your Network
CAP 130 P9 APs provide higher throughput and lower latency than earlier series APs and support
configuring the high-priority channel per SM. CAP 120 APs do not provide the higher throughput
and lower latency, but they do support configuring the high-priority channel per SM.
MIB File Set Compatibility
Although MIB files are text files (not software), they define objects associated with configurable
parameters and indicators for the module and its links. In each release, some of these parameters
and indicators are not carried forward from the previous release, and some parameters and
indicators are introduced or changed.
For this reason, use the MIB files from your download to replace previous MIB files in
conjunction with your software upgrades, even if the file names are identical to those of your
previous files. Date stamps on the MIB files distinguish the later set.
Redeploying Modules
Successfully redeploying a module may involve
• maintaining full and accurate records of modules being redeployed from warehouse stock.
• exercising caution about
o software compatibility. For example, whether desired features can be enabled with the
redeployed module in the network.
o procedural handling of the module. For example
◦ whether to align the SM or BHS by power level and jitter or by only jitter.
◦ whether the module auto-senses the Ethernet cable connector scheme.
o hardware compatibility; for example, where a CMMmicro is deployed.
o the value of each configurable parameter. Whether all are compatible in the new
destination.
• remembering to use auto discovery to add the redeployed SM to the network in Prizm.
Wiring to Extend Network Sync
The following procedure can be used to extend network sync by one additional hop, as described
under Passing Sync in an Additional Hop on Page 96. Where a co-located module receives sync
over the air, the co-located modules can be wired to pass the sync as follows:
Procedure 33: Extending network sync
1. Connect the GPS Utility ports of the co-located modules using a sync cable with
RJ-11 connectors.
2. Set the Sync Input parameter on the Configuration page of the co-located AP or
BH timing master to Sync to Received Signal (Timing Port).
