2. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the
bezel pointing toward you.
3. Remove the compute node cover (see “Remove the compute node cover” on page 29 for instructions).
The RAID adapter uses a specific drive backplane.
• If you need to remove the RAID adapter to access components on the system board (for example DIMM
sockets 13-24), there is no need to remove the backplane.
• If you are removing only the RAID adapter to replace it, there is no need to remove the backplane.
To remove a RAID adapter, complete the following steps:

Step 1. Locate the RAID adapter and interposer card in the compute node. If interposer card is installed in
the compute node, remove the cable from the cable clip. This provides more space for pulling out
RAID adapter later.
Step 2. Rotate the lever on the drive backplane to disengage the RAID adapter from the backplane
connector.
Step 3. Slightly rotate the rear edge of the RAID adapter upward; then, remove it at angle as shown. Be
cautious of the flash power module as it sits under the overhang of the compute node front panel.

Step 4. With cable connected to the RAID adapter, carefully turn the RAID adapter over in your hand to
access the underside.
Step 5. Disconnect the cable by pressing the latch and pull the cable out of the RAID adapter.
