Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3
May 2002
Chapter 4 Maintenance
Database Backup and Restoration
Step 1 If you need to perform a card pull on an active TCC-I card, initiate a software reset on the active TCC-I
card first. (See the “Initiate a Software Reset” section on page 4-4).
Step 2 When the TCC-I is in standby mode, unlatch the top and bottom ejector levers on the TCC-I card.
Step 3 Pull the card outward from the slot until the lighted LEDs turn off.
Step 4 Wait 30 seconds. Reinsert the card and close the ejector levers.
Note The TCC-I card takes several minutes to reboot and display the amber standby LED after rebooting.
Note During bootup of the reinserted TCC-I card, the FMEC cards in the system will not be visible in the
CTC software. They will be visible in the software again after the TCC-I card has finished booting.
Note When a second TCC-I card is inserted into the shelf, it will synchronize its software, its backup
software, and its database with the active TCC-I. If its software version does not match the version
on the active TCC-I, the newly inserted TCC-I will copy from the active TCC-I. This copying will
take about 15 to 20 minutes. If its backup software version does not match the version on the active
TCC-I, the newly inserted TCC-I will copy the backup software from the active TCC-I. This copying,
again, will take about 15 to 20 minutes. Copying the database from the active TCC-I will take about
3 minutes. So, depending on the software existing in the new TCC-I, booting it up will take between
3 and about 40 minutes.
4.3 Database Backup and Restoration
When dual TCC-I cards are installed in the ONS 15454 SDH, each TCC-I card hosts a separate database.
If the working TCC-I card database fails, the protect card database is available. You can store a backup
version of the database on a CTC software workstation. This off-system storage should be part of regular
ONS 15454 SDH maintenance at approximately weekly intervals. It should also be performed to prepare
an ONS 15454 SDH for disasters.
Note E100-2 cards lose traffic for approximately 30 seconds when an ONS 15454 SDH database is
restored. The CARLOSS alarm appears and clears during this process. The traffic outage happens
during the spanning-tree reconvergence.
Note If you are restoring the database on multiple nodes, wait five minutes between each database
restoration.
