Nt6D66 Call Processor Card - Nortel Meridian 1 Replacement Manual

NT6D66 Call Processor Card

Use this procedure to replace an NT6D66 Call Processor (CP) card.
Replacing the CP in a nonredundant system, such as 51C, will disrupt
system operation. If possible, schedule the replacement at the lowest
traffic time (after midnight).
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.
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.
At some point in this procedure the system may initialize, causing a
momentary interruption in call processing.
Note: The following procedure can be performed on a system equipped
with NT5D61 IODU/C, NT5D20 IOP/CMDU, or NT6D63 IOP and
NT6D64 CMDU cards.
