v For a battery that is installed in PCI assembly slot 1: Route the remote battery cable from the ServeRAID controller down through the slot on the left side of the DIMM air baffle, through the notch on the left side of the DIMM air baffle, across to the notch in the microprocessor air baffle, and up to the battery on the remote battery tray. v For a battery that is installed in PCI assembly slot 2: Route the remote battery cable from the ServeRAID controller through the hole in the right side of the power supply (see the illustration detail). 14. To install another ServeRAID controller remote battery in the server, repeat steps 7 on page 127 through 12 on page 129. 15. Install the server cover. 16. Connect the power cords and all external cables, and turn on the server and peripheral devices. Note: The battery must recharge for at least 6 hours under normal operating conditions. To protect your data, the ServeRAID controller firmware changes the write policy to write-through until the battery unit is sufficiently charged. When the battery unit is charged, the ServeRAID controller firmware changes the write policy to write-back. 130 System x3650 M3 Types 4255, 7945, and 7949: Installation and User's Guide
