System Reset

Procedure: Replace the Alarm Interface Panel

Step 1 Remove the clear plastic cover from the AIP.

Step 2 Unscrew the two screws that hold the AIP in place.

Step 3 Grip the panel on each side.

Step 4 Gently remove the panel from the backplane.

Step 5 Remove the fan-tray assembly power cable.

Step 6 Attach the fan-tray assembly power cable to the new AIP.

Step 7 Place the new AIP on the backplane by plugging the panel into the backplane using the DIN connector.

Step 8 Replace the screws that secure the pane to the backplane.

Step 9 Reset both TCC+s, one at a time.

3.4 System Reset

You can reset the ONS 15454 TCC+ cards by using the Cisco Transport Controller (CTC) software, or

by physically reseating a TCC+ card (card pull). A software-initiated reset reboots the TCC+ and reloads

the operating system and the application software. Additionally, a card pull reset temporarily removes

power from the TCC+ and clears all buffer memory.

You can apply a software-initiated reset to either an active or standby TCC+ without affecting traffic,

but you should only perform a card pull on a standby TCC+. If you need to perform a card pull on an

active TCC+, put the TCC+ into standby mode first by performing a software-initiated reset on the card.

Note When a software-initiated reset is performed on an active TCC card or TCC+, the AIC card goes

through an initialization process and also resets. The AIC card reset is normal and will happen each

time an active TCC card goes through a software-initiated reset.

Warning

Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed

circuitry could constitute an energy hazard.

Procedure: Perform a Software-Initiated Reset

Step 1 Log into CTC.

Step 2 Right click on the TCC+ card to reveal a pull-down menu.

Step 3 Click Reset Card (see Figure 3-5).

Step 4 Click Yes when the “Are You Sure?” dialog box appears.

Step 5 Click OK when the “Lost connection to node, changing to Network View” dialog box appears.

Step 6 Confirm that the TCC+ is in standby mode after the reset.
