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 180 and “Removing a PCI adapter” on page 179.
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.
