Replacing the ServeRAID battery backup unit for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6

This topic describes the procedure for replacing a battery backup unit (BBU) on a ServeRAID adapter in 3958 DD4, DD5, and AP1 (DD4-based) servers.

Perform the following steps to replace a BBU on a ServeRAID adapter:

1. Prepare the system for FRU replacement (see Preparing the system for FRU replacement for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6).
2. Verify that the server is powered off by checking that the power LED is flashing on the operator information panel. Then, disconnect the power cords and all external cables as necessary to replace the device.
3. Remove the top cover (see Removing the top cover for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6).
4. Remove the top cover bracket (see Removing the top cover bracket for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6).
5. Pull the blue handle  1  on the RAID adapter carrier  2  up to extract it from the server (Figure 1).

6. Disconnect the SAS cables from the RAID adapter.
   Note: Mark the cables before removing them so they can be returned to their original positions.
7. Press the release latch  1  and remove the RAID adapter from the carrier (Figure 2).

8. Remove the battery carrier card and the battery  2  from the RAID adapter  1 . You must remove the three screws  3  to separate them (Figure 3).
   Note: The location of the screws will be different depending on the model of RAID adapter. The most current RAID adapter contains the three screws on the top of the BBU.

9. Install the replacement BBU onto the adapter using the three screws.
10. Install the RAID adapter onto the RAID adapter carrier.
11. Connect the SAS cables to the RAID adapter.
    Note: Attach the SAS cable from port 0 to the lower backplane and the SAS cable from port 1 to the upper backplane (if one is installed). See Figure 4 for port locations.

12. Slide the RAID adapter carrier and RAID adapter assembly  3  into the slot  1  on the side of the server (Figure 5). Make sure the carrier is flat against the side wall of the server so that the adapter is installed in the connector correctly.

13. Install the top cover bracket (see Replacing the top cover bracket for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6).
14. Install the top cover (see Replacing the top cover for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6).
15. Connect the cables and power cords.
16. Slide the server into the rack.
17. Turn on all attached devices and the server.
18. Upgrade the firmware level as described in Updating the firmware of an MR10k MegaRAID or ServeRAID M5015 card for the TS7650 Appliance or TS7650G (Gateway), ProtecTIER V3.3.6.
