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.
4 Remove all SAS hard drives. See "Removing a Hot-Plug Hard Drive" on page 73.
5 To remove the optical/diskette drive carrier, pull the release latch forward, then slide the carrier out of
the chassis. See Figure 3-18.
6 Remove 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.
7 Disconnect the control-panel cable from the control-panel cable connector on the front of the SAS
backplane. See Figure 6-3.
8 Disconnect the SAS, interface, and power cables from the back of the SAS backplane.
