2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the
Rack Installation Instructions
that comes with the server.
3. Remove the server cover. See “Removing the server cover” on page 89.
4. Locate the backplane. See “Components of server models with twelve 3.5-inch hard-disk-drive bays”
on page 36.
5. Remove all the installed 3.5-inch 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 172.
6. Record the cable connections on the backplane and then disconnect all cables from the backplane.
7. Carefully lift the backplane straight up slightly so that the small hooks
1
on the chassis are aligned
with the corresponding holes in the backplane. Then, slowly and carefully move the backplane to the
rear of the chassis until the hooks
1
pass through the holes in the backplane and then completely
remove the backplane out of the chassis.

8. 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.
Note:
Carefully handle the backplane by its edges.
9. Note the orientation of the new backplane and position it on the chassis so that the small hooks
1
on
the chassis pass through the corresponding holes in the new backplane. Then, carefully press the new
backplane straight down so that it is secured in place by the small retaining studs
2
on the chassis.
