Special Installation Instructions For the 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.
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.
Statement 1015
To install or replace an LSI BBU, follow these steps:
Step 1 Remove an LSI BBU:
a. Remove the three screws that secure the BBU to the BBU bracket on the fan tray (see Figure 3-18).
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. Place the new BBU over the BBU bracket on the fan tray and align the three screw-holes in the BBU
with the three standoffs on the bracket.
b. Replace the three securing screws that hold the BBU to the BBU bracket.
c. Replace the cable connector to socket J2 on the underside of the BBU.
