Unadminister Fiber Links (Simplex 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 INADS and causes errors that are very
difficult to clear.
The fiber links are administered to match hardware and the Fiber Optic Cable
Running List. Fiber link administration creates translation data by identifying the
endpoint pairs for each link. To properly unadminister the fiber links, this
translation data must be removed.

DS1 Converter circuit packs. Type

Enter.
Scroll through the screens until the carrier containing the circuit packs is

from the slot locations on the screen. Press
Enter when finished.
