Removing the 3.5" Hard-Drive Backplane
CAUTION: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came with
the product.
1 Turn off the system, including any attached peripherals, and
disconnect the system from its electrical outlet.
2 Remove all the hard drives. See “Removing a Hard-Drive Carrier” on
page 81.
3 Open the system. See "Opening the System" on page 117.
CAUTION: To prevent damage to the drives and backplane, you must remove the
hard drives from the system before removing the backplane.
CAUTION: 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.
