5001 FAIL Initialization failure: the Expansion Interface circu it pack reset suc cessfully and
restarted execution, but the Expansion Interface circuit pack c ould not
synchronize itself dur i ng hardware initializati on.
1. Issue the reset board PCSS command. If the circuit pack is on the Active
link, this procedure can be very destructive. If a test board PCSS shows
all the tests 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 EPN.
2. If the reset fails with the same error code, execute the test tone-clock PC
command where P is the network that contains this Expansion Interface
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 reissue the reset board PCSS command.
3. If the Expansion Interface circuit pack still fails to reset with the same error
code, replace the Expansion Interface 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, all users in the EPN 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 bac kplane connector in slot
belonging to Expansion Interface 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 the reset board PCSS
command 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 replac ed.
