5001 FAIL Initialization failure: Expansion Interface circuit pack reset successfully
and restarted execution. But the Expansion Interface circuit pack could not
synchronize itself during the self-test phase of the hardware initialization.
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: Expansion Interface circuit pack reset successfully
and restarted execution. But the Expansion Interface circuit pack has
determined that a lightwave transceiver was not attached to the backplane
connector when the Expansion Interface circuit pack was last reset. If this
system does not have duplicate Expansion Interface Links, all users in the
EPN will be without service until this problem is resolved. If this system
does have duplicate links, the backup Expansion Interface Link will be
unavailable until this problem is resolved.
1. Attach lightwave transceiver to 25-pair backplane 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 documentation.
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 Expansion Interface circuit pack
may need to be replaced.
