Removing and Replacing a Timing, Communication, and Control Plus Card

Removing and Replacing a Timing, Communication, and Control Plus Card

Use the following procedure to install a new Timing, Communication, and Control Plus (TCC+) card or to replace an existing TCC+ card. If two TCC+ cards are installed for redundant operation, one of the cards can be removed and replaced without interrupting system operations.

Note The product order number for the TCC+ card is UBR10-TCC+=

Step 1 Attach an antistatic wrist strap to your wrist and to a bare metal, unpainted surface on the chassis or frame.

Step 2 Face the back of the Cisco uBR10012 chassis. If necessary, clear aside enough interface and power cables to allow sufficient space to work.

Step 3 If installing a new TCC+ card, remove the blank slot cover and discard, and then proceed to step 8. Otherwise, disconnect the clock cables from the TCC+ card being replaced.

Step 4 Loosen the top and bottom captive screws on the TCC+ card (see Figure 5-33).
