The following figure illustrates the connectivity of the External Optical Bypass module.
To cable the External Optical Bypass module:
Step 1
Connect an optical cable (user supplied) between the GBE port on the Subscriber side network
element and the
SUB
port on the External Optical Bypass module.
Step 2
Connect an optical cable (user supplied) between the GBE port on the Network side network
element and the
NET
port on the External Optical Bypass module.
Verify that the links between the two network elements are active.
Step 3
Connect the
SUB
cable of the fiber of the External Optical Bypass module to the
SUB
GBE port
of the
SCE 1000
platform.
Rx <-> Tx
Step 4
Connect the
NET
cable of the fiber of the External Optical Bypass module to the
NET
GBE port
of the
SCE 1000
platform.
Rx <-> Tx
Step 5
Power up the
SCE 1000
platform, as explained in
Starting the System and Observing Initial
Conditions
(on page
7-2
).
Warning
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, should be configured to
Auto-Negotiation = OFF
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 loop back on these
interfaces.
Step 6
Connect the control cable (supplied in the kit) from the
Bypass
9-pin D-Type connector on the
rear panel of the
SCE 1000
platform to the
Control
connector on the External Optical Bypass
module.
The
SCE 1000
platform immediately starts providing power to the External Optical Bypass
