Removing the system board

To remove the system board, complete the following steps.

1. Read the safety information that begins on page vii and “Installation guidelines”

on page 73.

2. Turn off the server and all attached devices; then, disconnect all power cords

and external cables.

3. Turn the server on its side so that it is lying flat, with the cover facing up.

4. Unlock and remove the side cover (see “Removing the side cover” on page

78).

5. Rotate the power-supply cage assembly out of the chassis:

v Hot-swap models:

a. Remove the hot-swap power-supply. Press down on the orange release

lever and pull the power supply out of the bay, using the handle.

b. Lift up the power-supply cage handle and pull the power-supply cage

assembly all the way up until the retainer latch locks the cage in place

on the chassis.

v Non-hot-swap models, lift up the power-supply cage handle and pull the

power-supply cage assembly all the way up until the retainer latch locks the

cage in place on the chassis.

6. Remove the front fan-cage assembly (see “Removing the front system fan

cage assembly” on page 108.

7. Note where each cable is connected; then, disconnect all cables from the

system board.

8. Remove any of the following components that are installed on the system

board and put them in a safe, static-protective place:

v Adapters (see “Removing an adapter” on page 81).

v Microprocessor and heat sink (see “Removing the microprocessor and heat

sink” on page 137).

v DIMMs (see “Removing a memory module” on page 97).

Note: If you replace the system board and need to remove the DIMM

thermal baffles from the non-functional DIMM connectors 3, 6, 9, and 12,

use a pointing object and align it through the holes on the end of the DIMM

thermal baffles and press down on the release clip to release the thermal

baffles.

v Battery (see “Removing the battery” on page 114).

9. Rotate the rear system fan air baffle up out of the way by grasping the tab and

pulling the baffle all the way up; then, slide it outward over the rear of the

server until it locks in place.

10. Rotate the system board retention latch toward the rear of the chassis.
