Chapter 3 Maintaining the Server
Installing or Replacing Components
Replacing an LSI MegaRAID Battery Backup Unit
When you install an LSI MegaRAID card and the optional BBU in this server, do not install the BBU on
top of the card as described in the LSI instructions. To avoid overheating the card, you must install the
BBU on a special bracket that is located on the fan tray.
Note LSI recommends that you replace the LSI BBU once per year or after 1,000 recharge cycles, whichever
comes first. Verify whether BBU replacement is required by looking in the CIMC. Log in to CIMC for
the server, then click Server—Inventory—Storage—Battery Backup Unit. If the Battery Replacement
Required field says, “True,” then you must purchase a replacement BBU and replace it.
Warning
There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the
same or equivalent type recommended by the manufacturer. Dispose of used batteries according to
the manufacturer’s instructions.

Note The instructions for installing the BBU differ depending on which BBU version you are installing. The
newer LSIiBBU08 version requires that you replace the server’s mounting bracket. Procedures for both
LSIiBBU06 and LSIiBBU08 are included here.
This section includes the following procedures:
• Replacing an LSIiBBU06 BBU, page 3-40
• Replacing an LSIiBBU08 BBU, page 3-42
Replacing an LSIiBBU06 BBU
This BBU is supported by Cisco for use with the following RAID controller cards:
• LSI MegaRAID 9260-4i (Cisco product ID R200-PL004, LSI 6G MegaRAID 9260-4i
card w/512MB write cache)
• LSI MegaRAID 9280-4i4e (Cisco product ID UCSC-RAID-C-4i4e, LSI 9280-4i4e)
To install or replace an LSIiBBU06 version BBU, follow these steps:
Step 1 Remove a BBU:
a. Remove the three screws that secure the BBU to the BBU bracket on the fan tray (see Figure 3-24).
b. Disconnect the cable from the BBU. If you are only replacing a BBU and not the LSI card, you do
not have to disconnect the other end of the cable from the card.
Step 2 Install a BBU:
a. Install the cable that is connected to the LSI controller card to socket J2 on the underside of the BBU.
