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 a 2488H V5.

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.
   • If the server is configured with two processors, the supercapacitor can be installed on the air duct or mainboard.
   • If the server is configured with four processors, install the supercapacitor on the mainboard or the side wall of the PSU.

     Figure 8-65 Positions of the supercapacitors (four processors)
     

7. Check whether the supercapacitor is configured with a TFM.
   • If yes, go to 8.
   • If no, go to 9.

8. Remove the TFM.
   1. Remove the PCIe RAID controller card.

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

   2. Unscrew the TFM on the PCIe RAID controller card. See (1) in Figure 8-66.
   3. Remove the TFM from the RAID controller card. See (2) in Figure 8-66.

   4. Go to 10.

9. Remove the cable between the supercapacitor and the RAID controller card.

10. Remove the supercapacitor and its holder.
    • If the supercapacitor is installed on the air duct
      1. Press the latch and remove the supercapacitor and its holder from the air duct.

      2. Open the plastic buckles that secure the supercapacitor. See (1) in Figure 8-69.
      3. Exert even force to lift the supercapacitor out of the holder. See (2) in Figure 8-69.
         Figure 8-69 Removing a supercapacitor
         
    • If the supercapacitor is installed on the side wall of the PSU
      1. Lift the supercapacitor holder as far as it will go, and pull out the supercapacitor holder.

      2. Open the plastic buckles that secure the supercapacitor. See (1) in Figure 8-71.
      3. Exert even force to lift the supercapacitor out of the holder. See (2) in Figure 8-71.

    • If the supercapacitor is installed on the mainboard
      1. Open the plastic buckles that secure the supercapacitor. See (1) in Figure 8-72.
      2. Exert even force to lift the supercapacitor out of the holder. See (2) in Figure 8-72.

      3. Loosen the screws that secure the supercapacitor holder. See (1) in Figure 8-73.
      4. Lift the supercapacitor holder. See (2) in Figure 8-73.

11. Place the removed component in an ESD bag.

    Place only one component in an ESD bag.
