Systems with nonduplicated SPEs

1 Power down the control carrier.
2 Remove the suspected circuit pack.
3 Determine whether the backplane pins in the removed circuit pack's slot are bent.
4 If the backplane pins are bent:
a Straighten or replace the pins.
b Insert the same circuit pack.
If not, replace the circuit pack (reinsert the old one if a replacement is not available).
5 Turn the power back and allow the system to reboot. This may take up to 12 minutes. Log in at the
terminal.
6 Determine whether the packet-bus fault is still present. If not, you are finished.
If the problem is still present,
a If the old circuit pack was reinserted in
b If the circuit pack was replaced in
If Procedure 3 fails to identify the cause of the problem, go to Procedure 4.
High- and critical-reliability systems
1 To remove a PN's IPSI circuit pack, use set ipserver-interface Uc if necessary to make the
suspected circuit pack the standby. (Before executing an interchange, always check the status of
the standby IPSI's Tone-Clock circuit with status port-network.)
To remove a PN's Tone-Clock circuit pack, use set tone-clock if necessary to make the suspected
circuit pack the standby. (Before executing an interchange, always check the status of the standby
Tone-Clock with status port-network.)
2 Determine whether the backplane pins in the removed circuit pack's slot are bent.
3 If the pins are bent:
a Power down the carrier if it is not already.
b Straighten or replace the pins.
c Insert the same circuit pack.
d Restore power to the carrier.
4 If the backplane pins are not bent, reinsert or replace the circuit pack.
5 Determine whether the packet-bus fault has been resolved. If so, you are finished.
If not, do the following:
a If the old circuit pack was reinserted in
Procedure 3 starting at
b If the circuit pack was replaced with a new one, proceed with
