Remove a RAID adapter
Use this information to remove a RAID adapter.
Before you remove the RAID adapter, complete the following steps:
1. Read “Safety” on page iii and “Installation Guidelines” on page 21 to ensure that you work safely.
2. Power off the corresponding compute node that you are going to perform the task on.
3. Remove the compute node from the chassis (see “Remove the compute node from the chassis” on page
24).
4. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the
bezel pointing toward you.
5. Remove the compute node cover (see “Remove the compute node cover” on page 42).
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 the RAID adapter, complete the following steps:
Watch the procedure. A video of the installation process is available:

Step 1. Locate the RAID adapter installed in the compute node.
Step 2. Remove the RAID adapter.

a. Rotate the lever on the hard disk drive backplane to disengage the RAID adapter from the
backplane connector.
b. Lift the RAID adapter and remove it from the compute node.
