CAUTION: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. See your Product

1

from the electrical outlet.

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

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

Remove fans 1 and 3 or 2 and 4 (depending on which fan interposer board
is being replaced). See "Removing a Cooling Fan" on page 67.

Remove the SAS backplane (systems with 3.5" hard drives) or peripheral
interposer board (systems with 2.5" hard drives). See "SAS Backplane
(Service-Only Procedure)" on page 122 or "Peripheral Interposer Board" on
page 126.
