Installing 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. Check whether a full-height full-length PCIe riser module is installed.
   • If yes, go to Step 7.
   • If no, go to Step 8.

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

   For details, see Removing a PCIe Riser Module.

8. Take the spare part out of its ESD bag.
9. Determine the position of the supercapacitor.
10. Insert the supercapacitor into the holder until the supercapacitor is locked.

12. Check whether the supercapacitor is configured with a TFM.
    • If yes, go to Step 13.
    • If no, go to Step 14.

13. Install the TFM.
    1. Remove the screw-in RAID controller card.
       1. Remove the cable from the RAID controller card.

          For details, see Internal Cabling.

       2. Loosen the screws that secure the RAID controller card. See (1) in Figure 8-82.
       3. Remove the RAID controller card from the connector on the mainboard. See (2) in Figure 8-82.
       Figure 8-82 Removing a screw-in RAID controller card
       
    2. Install studs on the TFM. See (1) in Figure 8-83.
    3. Insert the TFM into the screw-in RAID controller card. See (2) in Figure 8-83.
    4. Tighten the screws to secure the TFM. See (3) in Figure 8-83.

    5. Install the screw-in RAID controller card.

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

    6. Go to Step 15.

14. Connect the cable between the supercapacitor and the screw-in RAID controller card.
15. Check whether a full-height full-length PCIe riser module is installed.
    • If yes, go to Step 16.
    • If no, go to Step 17.

16. Install the full-height full-length PCIe riser module.

    For details, see Installing a PCIe Riser Module.

17. Install the chassis cover.

    For details, see Installing the Chassis Cover.

18. Install the server.

    For details, see Installing a Server.

19. Connect the power cables to the PSUs.

    For details, see Connecting PSU Cables.

20. Power on the server.

    For details, see Power-On Procedure.

21. Log in to the iBMC WebUI, and check whether the new component is normal.

    For details, see Atlas 800 Inference Server iBMC User Guide (Model 3010).
