Removing the ServeRAID SAS controller from the SAS riser-card
The following procedure is for a Tier 1 customer replaceable unit (CRU).
Replacement of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at
your request, you will be charged for the installation. Service agreements can be
purchased so that you can ask IBM to replace these units.
Note: Before running a procedure, refer to “Removing a file module to perform a
maintenance action” on page 51.
A ServeRAID SAS controller is installed in a dedicated slot on the SAS riser card.
Note: For brevity, in this documentation the ServeRAID SAS controller is often
referred to simply as SAS controller.
Important: If an 8-disk-drive optional expansion device in a 16-disk drive is
installed in a 12–drive-capable server, the SAS controller is installed in a PCI
riser-card assembly. Install and remove the SAS controller the same way as any
other PCI adapter. Do not use the instructions in this topic. Use the instructions in
“Installing a PCI adapter in a PCI riser-card assembly” on page 103.
