Installing SG 2000 Optical Modules

The design of the SG 2000 optical modules enable you to install them while the node is in service.
To install an optical module:
1
Determine the proper slot for the module by referring to the Forward Path RF Configuration or
the Return Path RF Configuration information in the beginning of this section. Position the
module in the appropriate slot and press gently on the casting until it is fully seated. Tighten the
two mounting bolts to secure the module in the SG 2000 lid.
2
Remove the dust covers from the service cable connector and the module's optical connector.
3
Carefully clean the optical connector using a suitable optical cleaning kit.
4
Connect the service cable to the module's optical connector.
5
If necessary, check the optical power levels. Check and align the RF levels in accordance with
system requirements and procedures.

Removing SG 2000 Optical Modules

The SG 2000 optical modules design enables you to remove them while the node is in service.
CA UT ION!
The module surfaces may be hot. Allocate sufficient time for the module to cool before
handling.
To remove an optical module:
1
Disconnect the service cable from the optical connector assembly on the module. Place dust
covers on the service cable connector and the modules optical-connector assembly.
2
Loosen the two mounting bolts that secure the optical module in the SG 2000 lid.
3
Pull the module from the SG 2000 lid using the wire handle on top of the module.
