NT6D65 and NTRB34 Core to Network Interface Cards

553-3001-520 Standard 16.00 April 2000
Replacing equipment
Use this procedure to replace the Core to Network Interface (CNI) or Core to
Network Interface 3 (CNI-3) card. See the X11 Administration
(553-3001-311) for a description of all maintenance commands, and the X11
System Messages Guide (553-3001-411) for interpreting system messages.
Replacing the CNI card in a nonredundant system, such as 51C, will
disrupt system operation. If possible, schedule the replacement at the
lowest traffic time (after midnight).
Module covers are not hinged; do not let go of the cover. Lift the cover
away from the module and set it out of your work area.
Before replacing a CNI or CNI-3 card, you can test it in an unused CNI slot
(in case, for example, there is a bent pin on the backplane). If the card works
correctly in the new slot, you can leave it there. To switch slots:
• The Core associated with the CNI card must be inactive:
— If you need to switch Cores:
LD 135
SCPU
— Set the NORM/MAINT switch to MAINT on the active CP card.
• Software disable the CNI card:
DIS CNI c s
****
• Software configure the new slot:
LD 17
EXT x 3PE
CNI X s p
