See "Installing an Expansion Card" on page 75 for general instructions about installing the controller card. See the controller card documentation for specific information on installing and configuring the card.

NOTICE: If your SAS controller has an external storage connector, you must install the optional PCI fan assembly in your system to maintain the proper cooling environment. Failure to install the fan assembly could result in the system overheating and shutting down unexpectedly. See "Installing the PCI Fan Assembly" on page 72 for instructions on installing the PCI fan assembly.
