• Install the upper compute tray or storage tray. See “Install a compute tray” on page 307 or “Install the
storage tray (fully removed)” on page 377.
• Install the front cover. See “Install the front cover” on page 322.
If you are instructed to return the backplane, follow all packaging instructions and use any packaging
materials that are provided.
Remove a hard disk drive backplane (lower tray)
Hard disk drive backplanes in the lower compute tray are accessed from the front of the server. There are
several types of hard disk drive backplane. Steps that are backplane specific are noted in each procedure.

CAUTION:
The power-control button on the device and the power switch on the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one power cord. To
remove all electrical current from the device, ensure that all power cords are disconnected from the
power source.

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 322.
2. After noting their locations, remove any hard disk drives that are installed in the lower compute tray. See
“Remove a hard disk drive” on page 323.
3. Remove the lower compute tray. See “Remove a compute tray” on page 305.
4. Remove the fan cage. See “Remove a fan cage (lower tray)” on page 316.
5. Move or remove the storage interposer to access the hard disk drive backplanes. See “Remove a
storage interposer (lower tray)” on page 371.
6. Move cables and harnesses to provide a clear path for accessing the hard disk drive backplanes and
their connectors.
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 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,
