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.
