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.
