Chapter 12 Maintenance
Database Backup and Restore
Caution
Always use the supplied electrostatic discharge band when working with a powered ONS 15327. Plug
the wristband cable into the ESD jack located on the front of the ONS 15327.
Step 1
If you need to perform a hard reset on an active XTC card, first perform a soft reset on the active XTC
as described in the
“Perform a Software Reset” procedure on page 12-5
Step 2
When the XTC is in standby mode, unlatch both ejector levers on the XTC card.
Step 3
Physically pull the card at least partly out of the slot until the lighted LEDs turn off.
Step 4
Wait 30 seconds. Reinsert the card and close the ejector levers.
Step 5
The XTC will take several minutes to reboot. The Act/Stby LED glows amber during the reboot process.
The AUTORESET alarm clears at the end of the boot process.
12.4 Database Backup and Restore
Each XTC card installed in the ONS 15327 contains two copies of the database. A save to the flash
memory is written to the standby database, and the standby database then becomes the active database.
The previously active database then becomes available for writing the next time. With dual XTCS, the
standby XTC keeps both copies of the database synchronized with the active XTC as changes are made
so that it is ready to take over control as needed.
You can also store a back-up version of the database on
the workstation running CTC. Backing up the database should be part of a regular ONS 15327
maintenance program at approximately weekly intervals and should also be completed when preparing
an ONS 15327 for a pending natural disaster, such as a flood or fire.
Caution
If you are restoring the database on multiple nodes, wait five minutes between each database restore.
Caution
E10/100-4 cards lose traffic for approximately 90 seconds when an ONS 15327 database is restored.
Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm will appear
and clear during this period.
Note
The following parameters are not backed up and restored: node name, IP address, mask and gateway,
and IIOP port. If you change the node name and then restore a backed up database with different node
names, the circuits will map to the new node name. Cisco recommends keeping a record of the old
and new node names.
Note
You must back up and restore the database for each node on a circuit path in order to maintain a
complete circuit
