v Replacement Date – Copy the expiration date from the battery label on the
old controller.
Note: The preferred method of checking for the battery operating age is
through the storage server management software.
19. Position the battery inside the replacement RAID controller.
20. Reassemble the battery access panel to the RAID controller bottom panel by
aligning it with the three pins on the RAID controller bottom panel. Slide the
battery access panel toward the back until you can reinsert the screw that
holds the battery access panel to the RAID controller bottom panel. Do not
overtighten.
21. You must reconnect the battery harness to the two-pin connector on the
controller board.
Note: The connector is keyed so that there is only one way to attach the
harness to the connector. Do not force fit.
22. Flip the RAID controller bottom panel over and carefully place it on the
controller sides. Push the RAID controller bottom panel toward the front to
latch it to the side panels. If the controller bottom panel is placed correctly, you
should be able to access the mounting holes for the six screws that you
removed from step 7 on page 99. Reinsert the six screws. Do not overtighten.
23. Install the new RAID controller, as follows:
a. Slide the RAID controller all the way into the empty slot.
b. Close both levers until the latch locks into place. Power on the storage
server, if the storage server is not powered on already.
24. Insert the SFPs according to the instructions in "Installing SFP modules" on
page 46.
25. Connect the fibre-channel cables to their original locations, according to the
instructions in "Installing fiber-optic cables" on page 48. Connect any
secondary cables (such as Ethernet cables) in their original locations.
26. Wait approximately one minute, and then check the green Host Loop LED,
green Expansion Loop LED, and amber Fault LED on the new RAID controller.
v If the Host Loop LED or the Expansion Loop LED is off, the RAID controller
might not be inserted correctly. Remove the CRU and reinsert it.
v If the Fault LED is on, the Host Loop LED and the Expansion Loop LED
stay off, or any other Fault LED is on, see the DS4000 Storage Manager
client for problem determination.
27. Follow the appropriate procedure for the your DS4100 storage server model:
v For the DS4100 base storage server: When you replace the failed RAID
controller, the DS4000 Storage Manager client automatically updates the
firmware for the new controller to match the configuration database. After
you replace a controller, always use the DS4000 Storage Manager client to
verify the firmware levels and NVSRAM files.
Continue with step 28 on page 103.
v For the DS4100 single-controller storage server:
– If the firmware version of the replacement DS4100 RAID controller
matches the firmware version of the replaced DS4100 RAID
controller:
