CAUTION:
Make sure that all server power cords are disconnected from their power sources before performing
this procedure.
Before you remove the hard disk drive backplane:
1. Remove the front cover. See “Remove the front cover” on page 139.
2. After noting their locations, remove any hard disk drives that are installed in the upper tray. See
“Remove a hard disk drive” on page 140.
3. Remove the upper compute tray or storage tray. See “Remove a compute tray” on page 123 or
“Remove a storage tray” on page 187.
4. Turn the tray upside down.
5. Remove the fan cage. See “Remove a fan cage (upper tray)” on page 131.
Complete the following steps to remove the hard disk drive backplane:

Step 1. Disconnect all power and data cables on the hard disk drive backplane that go to the storage
interposer or to connectors on the compute system board or optional storage tray. You might find it
easier to disconnect cables from the backplane if you disconnect them from the storage interposer
first, reconnecting them to the storage interposer after removing the backplane or installing a new
one. Other cables might also need to be removed from their retaining clips or moved to the side to
remove the backplane.
Step 2. Turn the tray right-side up.
Step 3. Remove the hard disk drive backplane.
