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.

S002

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.

2. After noting their locations, remove any hard disk drives that are installed in the lower compute tray. See Remove a hard disk drive.

3. Remove the lower compute tray. See Remove a compute tray.

4. Remove the fan cage. See Remove a fan cage (lower tray).

5. Move or remove the storage interposer to access the hard disk drive backplanes. See Remove a storage interposer (lower tray).

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:

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, 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.
2. Remove the hard disk drive backplane.
