Removing Circuit Boards
Installing the Monitor board may require that you remove or reposition one or
more currently installed boards to make room for the new board or to meet internal
cabling constraints. When unplugging boards you may also find it necessary to
remove the screw mounting an adjacent circuit board, and in the case of some short
circuit boards, it might be necessary to remove an adjacent tall circuit board to ease
removal of the shorter board.
Use the following procedure to unplug circuit boards from the motherboard.
1. Remove all interior and rear panel cables from the circuit boards that are to
be removed.
2. Use the Torx tool with the T15 tip to remove the screw from the bracket
inside the chassis (
Ê
in Figure 3) and the screw through the rear panel
outside the chassis (
Ë
in Figure 3).
CAUTION: To avoid damage to the circuit board when removing or
installing it:
• Do not rock the circuit board 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.
3. Extract the circuit board. If the circuit board is a tall circuit board, 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 short 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 board.
