Notes:
• This topic applies only to server models that support 3.5-inch hot-swap hard disk drives.
• To clearly show the backplane, the system fans are omitted from the illustrations in this topic.
To replace the backplane for 3.5-inch hard disk drives, do the following:
1. Remove all 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. 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 73.
4. Locate the backplane. See "Server components" on page 29.
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 128.
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.
