Removing a ServeRAID SAS/SATA controller

Use this information to remove a ServeRAID SAS/SATA controller.

Before you remove the SAS/SATA adapter from the system board, complete the following steps:

1. Read Safety and Installation guidelines.
2. If the compute node is installed in a NeXtScale n1200 Enclosure, remove it (see Removing a compute node from a chassis for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.

You can replace the ServeRAID controller with another supported ServeRAID controller. For a list of supported ServeRAID controllers, see the Lenovo ServerProven website.

Note

For brevity, in this documentation the ServeRAID SAS/SATA controller is often referred to as the SAS/SATA adapter or the ServeRAID adapter.

To remove the SAS/SATA adapter from the system board, complete the following steps:

1. Remove the cover (see Removing the compute node cover).
2. Grasp the touch points on both sides of the riser cage. Then, lift up the riser cage out of the compute node.
