10.Remove the screw that holds the battery access panel. Carefully slide the access panel toward the front to unlatch it from the three pins mounted on the RAID controller bottom panel.

11.Remove the battery unit and place it on a dry, level surface. If this is a battery replacement, then replace the old battery with the new one and go to step 19 on page 101.

12.Unpack the new RAID controller.

Set the RAID controller on a dry, level surface away from magnetic fields. Save the packing material and documentation in case you need to return the RAID controller.

13.Place the replacement RAID controller CRU bottom up on a flat surface. Using a #2 Phillips head screwdriver, remove the six screws (three on each side of the RAID controller) that hold the RAID controller bottom panel to the sides of the RAID controller, as shown in Figure 75 on page 99.

14.Slide the RAID controller bottom panel away from the front side of the RAID controller (away from the SFP slots and black center latch) to unlatch it from the side panels.

15.Carefully flip over the RAID controller bottom panel.

16.Remove the screw that holds the battery access panel. Carefully slide the access panel toward the front to unlatch it from the three pins mounted on the RAID controller bottom panel.

17.If DHCP/BOOTP was used to automatically set the IP address of the controller, record the MAC address of the upgrade controller and modify the existing DHCP/BOOTP record of the RAID controller to be upgraded with the new MAC address. Failure to modify the DHCP/BOOTP record will result in problems trying to manage the storage server using the existing IP address. This step must be performed before you insert the upgrade controller into the DS4000 storage server.

18.Write the battery replacement information on the label on the battery pack. v Installed date – Write today’s date
