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 64.

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

3Open the system. See "Opening the System" on page 65.

4Remove the PEM. See "Removing the PEM or PEM Shell" on page 73.

5Remove the cooling shroud assembly. See "Removing the Cooling Shroud Assembly" on page 69.

NOTICE: To prevent damage to the drives and backplane, you must remove the SAS drives and 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.

6Remove all SAS hard drives. See "Removing a Hot-Plug Hard Drive" on page 108.

7To remove the optical drive carrier, pull the release latch forward, then slide the carrier out of the chassis. See Figure 3-24.

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.

8If you are removing a 3.5-inch drive backplane, disconnect the control-panel cable from the control-panel cable connector on the front of the backplane. See Figure 3-30.

9Disconnect the SAS data and power cables from the back of the SAS backplane.
