Reinstalling the Boards

MPEG Board Upgrade Installation

3. It may be necessary remove the top slot cover screw that mounts any

adjacent circuit boards to allow more give so board removal is easier (refer
to Figure 4 on page 13 for the location of the top screw). Use the Torx tool
with the T15 tip to do so.

4. Use the Torx tool with the T15 tip to remove the screws from the top of the

slot cover inside the chassis (

in Figure 4) and the screw through bottom of

the slot cover through the rear panel outside the chassis (

in Figure 4).

CAUTION: To avoid damage to the circuit board when removing or
installing it:

- Do not rock the circuit board from side to side in the EISA bus

connector — pull straight up to remove.

- Do not grasp or push on the rear-panel connectors when removing or

installing circuit boards in the card slots.

5. Extract the circuit board:

- If the circuit board is tall, use the extraction lever on the front of the board

and the extraction ring at the back of the board to lift the circuit board free
of the connectors on the motherboard.

- For shorter circuit boards, carefully grasp the board and lift upward to free

the circuit board from the motherboard connectors. You might need to
remove an adjacent tall board to get enough room for a safe hold on the
shorter board.

6. You may also need to remove slot covers for empty slots to prepare for the

installation of new or moved boards. If this is necessary, refer to step 4.

7. Place removed boards in the supplied antistatic bags. Fold the bags over to

protect the boards from any ESD exposure.

Reinstalling the Boards

Now that you have removed the boards from the chassis, you are ready to reinstall
them, along with MPEG boards. See Table 3 on page 5 for placement of EDR,
Fibre Channel, and MPEG boards. For information on placing other boards, refer
to Table 7 on page 34.

CAUTION: Forcing a board into the slot may result in bent connectors on the
mother board. Carefully follow the instructions in step 1 to avoid damaging
hardware.
