Replacing a Flexible NIC


This chapter applies to TaiShan 2280 V2 12-slot nodes and TaiShan 5280 V2 12-slot nodes.

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • ESD gloves
  • ESD wrist straps
  • ESD bags
  • Labels

Replacement Process

Replace a flexible NIC by following the process shown in Figure 22-1.

    2. Tighten the screws using a Phillips screwdriver to secure the flexible NIC, as shown in step 2 in the preceding figures.

  6. Install the chassis cover and put the storage node into the cabinet. For details, see Basic Operations.
  7. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Ensure that all cables are correctly connected and then power on the storage node. If the storage node is not powered on, press the power button on the front panel.
  8. Check the system status.

    On SmartKit, choose Home > Storage > Routine Maintenance > More > Inspection and check the system status.
    • If all inspection items pass the inspection, the inspection is successful.
    • If some inspection items fail, the inspection fails. Rectify the faults by taking recommended actions in the inspection reports. Perform inspection again after fault rectification. If the inspection still fails, contact Huawei technical support.

    For details, see the FusionStorage OBS Administrator Guide.
