Procedure 16
Removing the NT5D97
Step Action
1 Determine the cabinet and shelf location of the NT5D97 card to
be removed.
2 Disable Network Loop using LD 60. The command is DISL "loop
number."
The associated DCHI might need to be disabled first. The
faceplate switch ENB/DIS should not be disabled until both
PRI2/DTI2 loops are disabled first.
3 If the NT5D97 card is being completely removed, not replaced,
remove data from memory.
4 Remove cross connections at MDF to wall-mounted
cross-connect terminal.
5 Tag and disconnect cables from card.
6 Rearrange Clock Controller cables if required.
CAUTION
Clock Controller cables connecting the Clock
Controller and DDP2 card must NOT be routed
through the center of the cabinet past the power
harness. Instead, they should be routed around the
outside of the equipment shelves.
7 Remove the DDP2 card only if both loops are disabled. If the
other circuit of a DDP2 card is in use, DO NOT remove the card.
The faceplate switch ENB/DIS must be in the OFF (DIS) position
before the card is removed, otherwise the system initializes.
