SREPN Maintenance
Maintenance procedure
NOTE:
In an EPN the TN775C EPN Maintenance circuit pack monitors the sanity of
the Expansion Interface circuit pack. If the EI circuit pack should cycle
between sane and insane several times, the Maintenance circuit pack holds
the EI circuit pack reset.
Which EPN is survivable?
1. On the Release 9r system, type the list cabinet command and press
Determine which EPN is "watched" by Survivable Remote equipment by
looking for the lower-case "s" before the letters "EPN" in the Type field as
shown in

2. Once you have located the physical equipment, check to see whether the
Red SURVIVE MODE ON LED is on, indicating that the system is in
Survive Mode.
If a new Expansion Interface circuit pack is installed in the EPN and
the red LED stays on, remove the EPN Maintenance circuit pack
because it may be holding the new EI circuit pack reset.
This can happen when there is a link problem to the EPN, and the
EPN restarts several times.
Reinstall the maintenance circuit pack after the Expansion Interface
circuit pack is physically inserted and the EI circuit pack's red LED is
off.
