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. Issue the reset board PCSS command. If the circuit pack is in the active

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
2. Reset the circuit pack again.
3. If the reset fails with an Error Code other than 5002, refer to the
