Installing the Chassis Intrusion Switch

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Connect the intrusion-switch cable to its system board connector. See Figure 3-25.

2Align the two grooved sides of the top of the intrusion switch with the inside of the intrusion-switch clip and then gently, but firmly, press in the switch until it is fully seated. See Figure 3-25.

3If applicable, reinstall the heat sink onto processor 4. See "Processors" on page 62.

4Replace the top cooling shroud. See "Replacing the Cooling Shrouds" on page 50.

5Close the system. See "Closing the System" on page 47.

6Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.

SAS Backplane (Service-Only Procedure)

Removing the SAS Backplane

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1If applicable, remove the bezel. See "Removing and Replacing the Optional Front Bezel" on page 45.

2Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.

3Open the system. See "Opening the System" on page 46.

NOTICE: To prevent damage to the drives and backplane, you must remove the SAS drives and diskette/optical drive carrier from the system before removing the backplane.

NOTICE: You must note the number of each hard drive and temporarily label them before removal so that you can replace them in the same locations.

4Remove all SAS hard drives. See "Removing a Hot-Plug Hard Drive" on page 73.

5To remove the optical/diskette drive carrier, pull the release latch forward, then slide the carrier out of the chassis. See Figure 3-18.

6Remove the cooling shrouds. See "Removing the Cooling Shrouds" on page 49.

NOTICE: When disconnecting the control-panel cable, hold the white pull-tab next to the control-panel cable connector to prevent damage to the SAS backplane or the cable itself.

7Disconnect the control-panel cable from the control-panel cable connector on the front of the SAS backplane. See Figure 6-3.

8Disconnect the SAS, interface, and power cables from the back of the SAS backplane.
