Clearing Core Call Server faults 77
Action
Positively identify the eight digits engraved on
the face of the Security Device beneath the
Nortel logo (NT SDID) with the NT SDID on the
keycode floppy disk label, and verify the NT
SDIDs match.
Verify that you are using the correct Install
Program disk for your system.
Issue the ENLT command at the TTY.
Unseat the CP card and reinstall it. Make sure
all cables are securely connected. If the fault
remains, continue with this step.
Replace the cable to the Com 1 port. If the fault
remains, replace the CP PIV card.
If the CP card is replaced and the symptoms
persist, replace the Call Server.
Ensure the Enable/Disable switch is in the
enabled position. If the LED remains red, test
the card by entering
LD 135
TEST SUTL C 15
C represents the affected Call Server, either 0
or 1.
If the fault remains, replace the System Utility
card.
Stat RMD in LD 135 to obtain partition status.
Repartition if partition is corrupt or unreadable,
or replace the CF card.
Reinstall software or replace FMD.
Test cable, replace cable if necessary, and
make sure all equipment power is on.
Check configuration of LAN equipment (must be
set to autonegotiate).
