TCC Card to TCC+ Card Upgrade
Procedure: Upgrade the TCC Card to the TCC+ Card
Step 1 Physically replace the standby TCC card on the ONS 15454 with a TCC+ card.
a. Open the TCC card ejectors.
b. Slide the card out of the slot. This raises the IMPROPRMVL alarm which will clear when the upgrade
is complete.
c. Open the ejectors on the TCC+ card.
d. Slide the TCC+ card into the slot along the guide rails.
e. Close the ejectors.
Note The MEA (card mismatch) alarm appears because CTC recognizes a mismatch between TCC
card types. Disregard this alarm; it clears by the end of the procedure.
Note It takes approximately 20 or 30 minutes for the active TCC to transfer the system software
to the newly-installed TCC+. Software transfer occurs in instances where different software
versions exist on the two cards. During this operation, the LEDs on the TCC+ flash Fail and
then the active/standby LED flashes. When the transfer completes, the TCC+ reboots and
goes into standby mode after approximately three minutes.
Step 2 Right click the active TCC card to reveal a pull-down menu.
Step 3 Click Reset Card (Figure 3-11).
