Step 1. Remove the hard disk drive backplane.
Figure 90. Hard disk drive backplane (lower) removal
Grasp the backplane and pull it up and for easier access to the power and data cable connections.
Step 2. 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.
Step 3. Lift and remove the hard disk drive backplane from the compute tray.
If you are not installing another hard disk drive backplane, after you remove the hard disk drive backplane:
• Replace or reposition the storage interposer. See "Install a storage interposer (lower tray)" on page 252.
• Make sure that all cables are routed and connected.
• Install the fan cage. See "Install a fan cage (lower tray)" on page 203.
• Install the lower compute tray. See "Install a compute tray" on page 190.
• Install the front cover. See "Install the front cover" on page 205.
If you are instructed to return the backplane, follow all packaging instructions and use any packaging
materials that are provided.
