9.Turn the new ServeRAID-8k SAS controller so that the keys on the bottom edge align correctly with the connector.

10.Firmly press the ServeRAID-8k SAS controller straight down into the connector by applying pressure on both ends of the controller simultaneously. The retaining clips snap into the locked position when the controller is firmly seated in the connector.

Note: If there is a gap between the controller and the retaining clips, the controller has not been correctly installed. In this case, open the retaining clips and remove the controller; then, reinsert the controller.

11.Remove the battery from the ServeRAID-8k SAS Controller package.

12.Slide the battery mounting tabs into the battery mounting clips on the server wall that is next to the ServeRAID SAS controller connector.

13.Connect the battery to the ServeRAID-8k SAS Controller.

14.Replace the air baffle over the DIMMs. See the User Guide for more information.

15.Replace the riser-card assembly.

If you have other optional devices to install or remove, do so now. Otherwise, go to “Completingthe installation.”

Notes:

1.When you restart the server for the first time after you install a ServeRAID-8k SAS controller, 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.

The battery comes partially charged, at 30% or less of capacity. Run the server for 4 to 6 hours to fully charge the controller battery. The LED just above the battery on the controller remains lit until the battery is fully charged.

Until the battery is fully charged, the controller firmware sets the controller cache to write-through mode; after the battery is fully charged, the controller firmware re-enables write-back mode.

2.When you restart the server, you will be given the opportunity to import the existing RAID configuration to the new ServeRAID SAS controller.

Completing the installation

To complete the installation, complete the following steps:

1.Install the cover. See “Installingthe cover” on page 31 for more information.

2.Install the server in the rack cabinet. See the Rack Installation Instructions that come with the server for detailed information about how to install the server in a rack cabinet.
