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 83.
4. Locate the backplane. See "Components of server models with eight 3.5-inch hard disk drive bays"

drive bays. See "Installing or replacing a hot-swap hard disk drive" on page 148.
6. Note down the cable connections on the backplane and then disconnect all cables from the backplane.
7. Press each of the two latches on the chassis in the direction as shown until the latch snaps into the
open position and will not interfere with lifting up the backplane.
