Since the EPN Maintenance circuit pack supports environmental maintenance in
the EPN, trouble with the EPN Maintenance circuit pack can cause environmental
maintenance to falsely detect problems. These environmental MOs include
DC-POWER, EMG-XFER, EXT-DEV, and CUST-ALM.
Since communication to the EPN Maintenance circuit pack flows through the
SW-CTL (Switch Control) and the EXP-INTF (Expansion Interface) circuit packs,
any problems with these MOs can prevent communication with the EPN
Maintenance circuit pack.
If a repair procedure calls for the EPN Maintenance circuit pack to be replaced,
and the EPN has redundant Expansion Links, use the following procedure to
prevent an Expansion Links switch when the new EPN Maintenance circuit pack
is plugged in.
1. Determine the Standby Expansion Links by using the status system
command.
2. Busyout the Standby Expansion Links by issuing the busyout board
PCSS command where PCSS is the 4-character circuit pack address of the
Expansion Interface circuit pack in the EPN on the Standby link.
3. Replace the EPN Maintenance circuit pack.
4. Release the Standby Expansion Links by issuing the release board PCSS
command, where PCSS is the 4-character circuit pack address of the
Expansion Interface circuit pack in the EPN on the Standby link.
