Replacing the hot-swap hard-disk-drive backplane
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 59.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• The hot-swap hard-disk-drive backplane is sensitive to ESD. Ensure that you read and understand
“Handling static-sensitive devices” on page 60 first and carefully perform the operation.
• Depending on the model, your server might look slightly different from the illustrations in this topic.
• The illustrations in the following procedure show the backplane for 3.5-inch hard disk drives. For the
backplane for 2.5-inch hard disk drives, the replacement procedure is similar.
To replace the hot-swap hard-disk-drive backplane, do the following:
1. Remove all external media from the drives and turn off all attached devices and the server. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
2. Prepare your server. See “Removing or extending the server from the rack cabinet” on page 61.
3. Remove the server cover. See “Removing the server cover” on page 61.
4. Remove the cooling shroud. See “Removing and reinstalling the cooling shroud” on page 64.
5. Locate the hot-swap hard-disk-drive backplane. See “Server components” on page 25.
6. Remove all the installed hot-swap hard disk drives and dummy trays (if any) from the hard-disk-drive
bays. See “Installing or replacing a hot-swap hard disk drive” on page 123.
7. Record the cable connections on the backplane and then disconnect all the cables from the backplane.
8. Press the two latches 1 in the direction as shown until the latches are disengaged from the chassis.
Carefully lift the backplane straight up a little bit so that the small hooks on the chassis are aligned with
the corresponding holes in the backplane. Then, move the backplane to the rear of the chassis to
release the backplane from the hooks.

9. Touch the static-protective package that contains the new hot-swap hard-disk-drive backplane to any
unpainted surface on the outside of the server. Then, remove the new backplane from the package.
