Removing the Supercapacitor

Procedure

1. Power off the server.

   For details, see Power-Off Procedure.

2. Remove the power cables from the PSUs.

   For details, see Removing PSU Cables.

3. Remove the server.

   For details, see Removing the Server.

4. Place the server on the ESD workstation.
5. Remove the chassis cover.

   For details, see Removing the Chassis Cover.

6. Determine the position of the supercapacitor.
7. Check whether a full-height full-length PCIe riser module is installed.
   • If yes, go to Step 8.
   • If no, go to Step 9.

8. Remove the full-height full-length PCIe riser module.

   For details, see Removing a PCIe Riser Module.

9. Check whether the supercapacitor is configured with a TFM.
   • If yes, go to Step 10.
   • If no, go to Step 11.

10. Remove the TFM.
    1. Remove the screw-in RAID controller card.

       For details, see Removing the Screw-in RAID Controller Card.

    2. Unscrew the TFM on the screw-in RAID controller card. See (1) in Figure 6-79.
    3. Remove the TFM from the RAID controller card. See (2) in Figure 6-79.

    4. Go to Step 12.

11. Remove the cable between the supercapacitor and the RAID controller card.
12. Press the latch and remove the supercapacitor holder from the air duct.

13. Remove the supercapacitor from the supercapacitor holder.
    1. Open the plastic buckles that secure the supercapacitor. See (1) in Figure 6-81.
    2. Exert even force to lift the supercapacitor out of the holder. See (2) in Figure 6-81.
