Unadminister Fiber Links (Duplex Systems)
The fiber links routing to and from the EPN cabinet being removed must be
unadministered before removing
any
hardware from the cabinet.
!CAUTION:

Failure to unadminister fiber links before removing hardware causes

unnecessary alarm reports to INAD S and causes errors that are very

difficult to clear.

The fiber links are administered to matc h hardware and the Fiber Optic Ca ble
Running List. Fiber link administration creates translation data by identifying the
endpoint pairs for eac h link. To properly unadminister the fiber links, this
translation data must be removed .
1. Type list fiber and press Enter. All administered fib er connections are
displayed. Make note of the fi ber links to be removed.
2. Type change fiber link and press Enter. The Fiber Link Administration
screen appears. On screen 1:
a. Remove the Board Location: information for ENDPOINT-1 and
ENDPOINT-2. This is the cabinet, carrier, and slot that identifies the
physical location of an SNI or EI circu it pack that is the first
endpoint of the fiber link. Rep eat for the remaining endpoints.
b. The Board Type field is display only.
