Repositioning Circuit Boards
Installing the Slave EDR board may require repositioning one or more currently
installed boards to either make room for the new board or meet internal cabling
constraints. When unplugging boards it may also be necessary to remove a screw that
mounts an adjacent circuit board or, in the case of some shorter 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 a circuit board from the motherboard:
1.
Remove all interior and rear panel cables, if any, from the circuit board.
2.
Using a Torx tool with a T15 tip, remove the two bracket mounting screws: one
that anchors the top of the bracket from inside the chassis (
Ê in Figure 3) and one
that anchors the bottom of the bracket from the outside rear panel of the chassis
(
Ë in Figure 3).
CAUTION: To avoid damage to a circuit board during removal or installation: 1) Do
not rock the circuit board in the EISA Bus connector — pull it straight up. 2) Do not
grasp or push on the rear-panel connectors when removing or installing circuit
boards in the card slots.
