Notes:1. When you restart the server for the first time after you install a ServeRAIDcontroller with a battery, the monitor screen remains blank while the controllerinitializes the battery. This might take a few minutes, after which the startupprocess continues. This is a one-time occurrence.Important: You must allow the initialization process to be completed. If you donot, 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 serverfor 4 to 6 hours to fully charge the controller battery. The LED just above thebattery on the controller remains lit until the battery is fully charged.Until the battery is fully charged, the controller firmware sets the controllercache to write-through mode; after the battery is fully charged, the controllerfirmware re-enables write-back mode.2. When you restart the server, you are given the opportunity to import the existingRAID configuration to the new ServeRAID controller.Removing a memory module (DIMM)To remove a DIMM, complete the following steps:1. Read the safety information that begins on page vii and “Installation guidelines”on page 133.2. Turn off the server and peripheral devices and disconnect all power cords andexternal cables.3. Remove the cover (see “Removing the cover” on page 145).4. If you have the optional hot-swap rear hard disk drive cage installed, rotate it up(see “Rotating the optional hot-swap rear hard disk drive cage up” on page147).5. Remove the air baffle (see “Removing the air baffle” on page 148).6. Open the retaining clip on each end of the DIMM connector and lift the DIMMfrom the connector.Attention: To avoid breaking the retaining clips or damaging the DIMMconnectors, open and close the clips gently.DIMMRetainingclip7.
