Tab Battery Connector Figure 25. Installing a cache battery in the RAID controller b. Press down on the blue lift tab to secure the battery to the connector. c. Tighten the thumbscrew. 13. Install the RAID controller: a. Make sure that the lever on each side of the controller is down as far as it will go. b. Push the controller into the bay until it meets resistance (approximately 6 mm [0.25 in.] from the end of the chassis). c. While squeezing together the latch and lever, push both latches up as far as they will go. The controller will slide the rest of the way into the bay. 14. Reconnect the Ethernet cables that you removed in step 7 on page 43 to the RAID controller. 15. For a Fibre Channel RAID controller only: Install the SFP modules and the fiber-optic cables that you removed in step 8 on page 43. 16. For a storage subsystem with one controller installed: Turn on the power supply switches on the rear of the storage subsystem. 17. For a storage subsystem with two controllers installed: Move the I/O data back to the original controller: a. Open a Telnet session and connect to the alternate controller management port IP address. If the Telnet session is open from step 4a on page 43, go to step 17d. b. At the command prompt, enter admin. c. Enter the administrator password. d. Enter controller peer enable. e. Enter controller info. Information about the controller is displayed on the screen. If the information shows that the peer controller status is Not Ready, repeat this step until the status is Ready. f. Enter array failback. The I/O data is moved back to the original controller. 18. Wait approximately 10 minutes for the ServeRAID Manager program to come back online. Note: It might take from 15 minutes to a few hours for a new battery to become fully charged. The ServeRAID Manager program might show the battery as failed until it is fully charged. Controller caching is automatically disabled until the new battery becomes fully charged. Appendix A.

SFP
modules
and
the
fiber-optic
cables

Move
the
I/O
data
back
to
the
original
controller:
a.
