How to Cable the External Optical Bypass Module
Figure A-5
Connect an optical cable (user supplied) between the GBE port on the Subscriber side network element
Step 1
and the SUB port on the External Optical Bypass module.
Connect an optical cable (user supplied) between the GBE port on the Network side network element
Step 2
and the NET port on the External Optical Bypass module.
Verify that the links between the two network elements are active.
Connect the SUB cable of the fiber of the External Optical Bypass module to the SUB GBE port of the
Step 3
SCE 1000 platform.
Rx<->Tx
Connect the NET cable of the fiber of the External Optical Bypass module to the NET GBE port of the
Step 4
SCE 1000 platform.
Rx<->Tx
Power up the SCE 1000 platform, as explained in Starting the SCE 1000 Platform.
Step 5
Verify that the relevant GBE interfaces of the SCE 1000 platform are now in sync, as the External Optical
Bypass module is now active (in bypass), and is performing a loopback on these interfaces.
Auto-Negotiation should be configured identically for the two SCE 1000 platform GBE interfaces and
the GBE interfaces of the switch/router on either side of the External Optical Bypass module. It is
recommended that the two GBE interfaces of the SCE 1000 platform, as well as the GBE interfaces of
the switch/router on either side of the External Optical Bypass module, be configured to
Auto-Negotiation = OFF.
Connect the control cable (supplied in the kit) from the Bypass 9-pin D-Type connector on the rear panel
Step 6
of the SCE 1000 platform to the Control connector on the External Optical Bypass module.
