page 180 and “Removing a PCI adapter” on page 179.
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.
1 SAS riser card
2 RAID adapter
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 206; 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 “Removing the SAS riser
card and controller assembly” on page 200).
If you have other optional devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 227.
Notes:
1. When you restart the server for the first time after you install a SAS controller
with a battery, the monitor screen remains blank while the controller initializes
the battery. This might take a few minutes, after which the startup process
continues. This is a one-time occurrence.
Important: You must allow the initialization process to be completed. If you do
not, the battery pack will not work, and the server might not start.
