8. Install the SAS riser-card and controller assembly (see "Installing the SAS riser-card and controller assembly" on page 118). If you have other devices to install or remove, do so now. Otherwise, go to "Completing the installation" on page 139. 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. 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 are given the opportunity to import the existing RAID configuration to the new ServeRAID SAS controller. Installing an optional ServeRAID adapter advanced feature key To install an optional ServeRAID adapter advanced feature key, complete the following steps: 1. Read the safety information that begins on page vii and "Installation guidelines" on page 37. 2. Turn off the server and peripheral devices and disconnect all power cords and external cables (see "Turning off the server" on page 22). 3. Remove the cover (see "Removing the cover" on page 44). 4. Align the upgrade key with the connector on the ServeRAID adapter and push it into the connector until it is firmly seated. 124 System x3650 M3 Types 4255, 7945, and 7949: Installation and User's Guide
