Chapter 12 Upgrade Cards and Spans
NTP- D94 Upgrade STM-N Cards and Spans Automatically
Caution If your active TCC2 card resets during the upgrade before the new TCC2P card has come to a full standby
mode, remove the new TCC2P card immediately.
Step 7 When the newly installed TCC2P card is in standby, go to the active TCC2 and right-click the card.
Step 8 From the shortcut menu, click Reset Card.
Wait for the TCC2 card to reboot. The ONS 15454 switches the standby TCC2P card to active mode.
The TCC2 card verifies that it has the same database as the TCC2P card and then switches to standby.
Step 9 Verify that the remaining TCC2 card is now in standby mode (the ACT/STBY LED changes to amber).
Step 10 Perform Step 6 to physically replace the remaining TCC2 card with the second TCC2P card.
The ONS 15454 boots up the second TCC2P card. The second TCC2P card must also copy the database,
which can take approximately 10 minutes. Do not remove the card from the shelf during a database
transfer.
Step 11 If power-related alarms occur after the second TCC2P card is installed, complete the “DLP-D33
Measure Voltage” task on page 17-26. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for
information about clearing alarms.
Stop. You have completed this procedure.
