Set the new battery on a dry, level surface. Save all packing materials in case
you need to return the battery.
Note: The battery comes with a new battery label. You will need this label
later in the procedure.
3. Review all documentation that comes with the new battery for updated
replacement procedures and other information.
4. Use the Storage Manager client to locate the RAID controller that contains the
failed battery (the RAID controller Fault LED might be on).
5. Label each cable that connects to the RAID controller that contains the battery
that has failed. This ensures that all cables will be properly reconnected to the
RAID controller after you replace the battery.
6. Use the Storage Manager client to take offline the RAID controller that
contains the battery that has failed.
Attention: On DS4300 single-controller storage server Model 6LU/6LX, you
can not place the controller offline. Instead, you must power down the DS4300
storage server. For more information on preparation tasks, see the Important
note in the beginning of this section.
7. Remove the fibre-channel cables and the SFPs from the RAID controller that
contains the battery that has failed or is nearing its expiration date. For more
information, see “Working with SFPs and fiber-optic cables” on page 33.
8. Remove the RAID controller, as follows:
a. Push down on the latch, which is centered above the RAID controller. Pull
both levers at the same time out of the locked position.
b. Grasp the pull-rings; then pull on the levers and remove the RAID
controller.
9. Place the 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 72 on page 92.
10. 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.
11. Carefully flip over the RAID controller bottom panel. Disconnect the battery
harness on the battery from the two-pin connector on the controller board as
shown in Figure 73 on page 92.
12. 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.
13. Remove the battery unit and place it on a dry, level surface. If this battery is a
replacement battery, then replace the old battery with the new one.
14. Write the battery replacement information on the label on the battery pack.
v Installed date – Write today’s date
v Replacement Date – Write the date three years from today’s date
Note: The preferred method of checking for the battery operating age is
through the Storage Manager client.
