If you have other devices to install or remove, do so now. Otherwise, go to Completing the installation.

Removing a SAS controller from the SAS riser card

A SAS controller is installed in a dedicated slot on the SAS riser card.
Important: If you have installed a 4-disk-drive optional expansion device in a 12-drive-capable server, the
SAS controller is installed in a PCI riser-card assembly and is installed and removed the same way as any
other PCI adapter. Do not use the instructions in this topic; use the instructions in "Installing a PCI adapter"
on page 158 and "Removing a PCI adapter" on page 156.
Depending on the server model, the server comes with a ServeRAID-BR10i SAS/SATA controller or a
™ServeRAID-MR10i SAS/SATA controller installed.
You can replace the SAS controller with another supported SAS controller. For a list of supported RAID
controllers, see http://www.lenovo.com/thinkserver
Note: For brevity, in this documentation the ServeRAID SAS controller is often referred to as SAS controller.
