Installing the External Bypass Module
Power up the SCE 2000 platform, as explained in
Step 5
Verify that the relevant GBE interfaces of the SCE 2000 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 2000 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 2000 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 2000 platform to the Control connector on the External Optical Bypass module.
The SCE 2000 platform immediately starts providing power to the External Optical Bypass module, so
the bypass module becomes inactive, and starts transferring the traffic to the SCE 2000 platform. The
"No Bypass " LED should therefore be lit.
