12. 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 72 on page 90.
13. 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.
14. Carefully flip over the RAID controller bottom panel.
15. 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.
16. 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 FAStT storage
server.
17. Position the battery inside the replacement RAID controller.
18. 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.
19. 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.
20. 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 6 on page 89. Reinsert the six screws. Do not overtighten.
21. 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.
Attention:
When you replace the failed RAID controller, the
storage-management software automatically synchronizes the firmware
between the existing controller and the new controller. After you replace a
controller, always use the storage-management software to verify the firmware
levels and NVSRAM files.
22. Insert the SFPs according to the instructions in "Installing SFP modules" on
page 34.
23. Connect the fibre-channel cables to their original locations, according to the
instructions in "Installing fiber-optic cables" on page 36.
24. 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.
