operating normally, unpredictable provisioning of the replaced/installed
circuit pack can result.

CAUTION:
Ensure that protection switching is available (protection circuit pack

available, use a CIT and a protection
switch-line:
command to do a
protection switch.

CAUTION:
When removing circuit packs, always remove the one without the lighted
ACTIVE
LED first.
NOTE:
When a replacement circuit pack (except the SYSCTL) is configured the
same as the original circuit pack, it may be inserted with no further action.
When a replacement circuit pack is different (different code or different
switch options) from the original, the SYSCTL UPD/INIT button must be
momentarily depressed to update the inventory.
