3. If necessary, refer to FIBER-LK Maintenance object in Chapter 9 of
DEFINITY ECS Release 9 Maintenance for R9r
for more information.
Reconnect the Release 9r to the EPN
!
CAUTION:
Ensure that the links are repaired before proceeding with the next section.
See ‘‘Fault isolation procedures’’ for troubleshooting help.
To reconnect the SREPN to the Release 9r:
1. Set the switch on the TN2301 circuit pack to the RSTR position for at least
1 second and return the switch to the AUTO position.
OR
From a remote dial-in connection to the SRP, use the restore survivable-
remote-link command to reset the SRP. See the ‘‘Restore from remote
location’’ section later in this chapter.
2. Check for the following LED status:
■ Red (SURVIVE MODE ON) is off
■ Green (AUTO) is on steady, meaning that the SREPN is ready to
assume processor control for the EPN should another link failure
occur.
3. Wait at least 3 minutes while the EPN goes through its cold restart.
4. Check the status of the link connections (status health)
on both the
Release 9r and the SRP systems
to determine whether the link between
the Release 9r and the EPN is up (Figure 2-9 on page 2-17).
