EXP-INTF (Expansion Interface Circuit Pack)
Issue 1 June 2005 1233
5001 FAIL Initialization failure: the EI circuit pack reset successfully and restarted
execution, but the EI circuit pack could not synchronize itself during
hardware initialization.
1. Enter reset board PCSS. If the circuit pack is in the active link, this
procedure can be very destructive. If a test board PCSS shows
every test passing, and there is no standby link to which you can
switch, perform this reset at a time when service is least disrupted by
losing use of the PN.
2. If the reset fails with the same error code, execute test tone-clock
PC where P is the network that contains this EI circuit pack and C is the
carrier that contains the active Tone-Clock on network P. Also look for
SYNC and TONE-BD errors. Resolve any SYNC and TONE-BD errors
by following the Maintenance documentation for these MOs. Then
execute reset board PCSS.
3. If the EI circuit pack still fails to reset with the same error code, replace
the EI circuit pack.
5002 FAIL Initialization failure: EI circuit pack reset successfully and restarted
execution. But the EI circuit pack has determined that a lightwave
transceiver was not attached to the backplane connector when the EI
circuit pack was last reset. If this system does not have duplicate EI links,
every user in the PN will be without service until this problem is resolved. If
this system does have duplicate links, the backup EI link is unavailable
until this problem is resolved.
1. Attach lightwave transceiver to 25-pair backplane connector in slot
belonging to EI circuit pack.
2. Reset the circuit pack again.
3. If the reset fails with an Error Code other than 5002, refer to the
appropriate maintenance section.
4. If the reset fails again with Error Code 5002, replace the lightwave
transceiver, reset the circuit pack, and execute test board PCSS
again.
5. If the reset fails again with Error Code 5002, the new lightwave
transceiver may be defective, or the EI circuit pack may need to be
replaced.
