Xserve Logic Board - 12
Installing the Replacement Logic Board
1. If the heatsink thermal pad on the underside of the replacement logic board has
protective film on it, remove the film. (Figure 14)
Note: The protective film is a very thin layer on top of the thermal pad. Be careful to
remove only the film, not the pad.
Figure 14
2. Install the replacement logic board in the bottom housing, making sure the board fits
over the four mounting pegs on the chassis floor.
Important: Make sure the board’s connectors fit through the appropriate openings in
the server’s back panel. Take special care to fit the clear plastic system identifier
button through its opening. (The system identifier button is located low on the back
panel, to the left of center.) (Figure 15)

3. Tighten the thumb screw that secures the logic board to the chassis.
