Installing a SAS controller 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 56 and “Removing a PCI adapter” on page 54.
To install a SAS controller on the SAS riser card, complete the following steps:
1. Make sure that the server is turned off, all external cables and power cords are
disconnected, and the cover has been removed.
2. If you are installing a new or replacement SAS controller, touch the
static-protective package that contains the new SAS controller to any unpainted
metal surface on the server. Then, remove the SAS controller from the package.

3. If you are installing a new or replacement SAS controller that uses a battery,
complete the following steps:
a. Remove the battery from the SAS controller package or the battery
package.
b. Install the battery and connect the battery to the SAS controller as instructed
in the documentation that comes with the SAS controller or the battery.
4. If the new SAS controller is a different physical size than the SAS controller you
removed, you might have to move the controller retention bracket (tape-enabled
model servers only) to the correct location for the new SAS controller. See
“Moving the SAS-controller retention bracket” on page 82; then, continue with
the next step in this procedure.
5. Turn the SAS controller so that the keys on the bottom edge align correctly with
the connector on the SAS riser card in the SAS controller assembly.
6. Firmly press the SAS controller horizontally into the connector on the SAS riser
card.
7. (Tape-enabled model server only) Gently press the opposite edge of the SAS
controller into the controller retention bracket.
8. Install the SAS riser card and controller assembly (see “Installing the SAS riser
card and controller assembly” on page 78).
If you have other optional devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 100.
