Installing a Clock+ Board

If you are replacing the clock+ board, then the TOD NVRAM from the old board must be removed and placed on the new board. Note also that if a system is replaced, then the TOD NVRAM on the clock+ board must also be changed.

1. Carefully insert the board in the proper slot in the card cage, ensuring that the board does not slip out of the left and right card guides.

   The component side of the board must face up.

2. Ensure that both extraction levers are in the outward position as you slide the board toward the backplane connectors (Figure 6-2).

   The board will not seat fully unless the levers are in this starting position.

   Caution -

   DO NOT FORCE any board into a slot; this can cause damage to the board and system. The board should insert and seat smoothly. If it binds, remove the board and inspect the card cage slot for any obvious obstructions. Also inspect both the board and the backplane for bent pins or other damage.

3. Use the extraction levers to seat the board.

   Simultaneously swing both levers into the locked position. Do not press on board front panel to seat it--doing so will damage the connector pins.

4. Secure the board to the chassis using the two captive screws, one on each side.

5. Connect any applicable interface cables to the front panel of the board.

6. Turn on system power. See Chapter 11, Powering Off and On for this procedure.

7. Boot the system.
