Installing the BS-GU module
Inserting the BS-GU Module and Connecting
It to the Antenna
1.
Carefully insert the BS-GU module into any of the free suitable slots in the
BS-SH chassis and push firmly until it is securely locked. Close the captive
screws attached to the module.
2.
Connect the 9-pin micro D-Type connector of the GPS cable to the
SYNC IN connector (the top-left connector) of the BS-GU module.
Daisy-chaining Two or More BS-GU
Modules
If two or more BS-GU modules are installed in different collocated
BS-SH chassis, use a synchronization cable (supplied separately) to
connect the
SYNC OUT connector of the first (Master) module to the
SYNC IN connector of the second module. The SYNC OUT of this second
module may be connected to the SYNC IN of a third module, and so on.
NOTE:
Outdoor units and antennas should be installed ONLY by experienced installation
professionals who are familiar with local building and safety codes and, wherever
applicable, are licensed by the appropriate government regulatory authorities.
Failure to do so may void the BreezeACCESS product warranty and may expose the
end user or the service provider to legal and financial liabilities. Alvarion and its resellers
or distributors are not liable for injury, damage or violation of regulations associated with
the installation of outdoor units or antennas.
NOTE:
When adding the BS-GU to an active base station, it is recommended to start by
reconfiguring the AU previously defined as Master to Slave, then immediately inserting
and configuring the
Number of Hopping Frequencies parameter in the BS-GU
module. Otherwise both the Master AU and the BS-GU will send conflicting
synchronization signals to the Slave AUs. During this process, connectivity with the
Subscriber Units will be interrupted. It is recommended to perform the upgrade during a
planned downtime or at a time of minimal traffic. Properly configuring the value of the
Number of Hopping Frequencies parameter in the BS-GU is mandatory for proper
operation of the base station. All other parameters of the BS-GU module may be
configured later as they do not impact the operation of the system.
WARNING:
Deactivate the power to the BS-GU unit before connecting it to a GPS antenna. Switch
on the BS-GU only after the GPS antenna has been connected.
