Replacing a Riser Card of a TaiShan 2280 12-Slot Node or TaiShan 5280 36-Slot Node

Replacing a Riser Card of a TaiShan 2280 12-Slot Node or TaiShan 5280 36-Slot Node

A riser card provides interfaces for a Peripheral Component Interconnect Express (PCIe) card.

Impact on the System

Before replacing a riser card on a storage node, you must power off the node. This will adversely affect the services running on the node.

Prerequisites

  • A spare riser card is ready.
  • The faulty riser card has been located.

Precautions

None

Tools and Materials

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

Replacement Process

Replace a riser card by following the process shown in Figure 19-9.

Figure 19-9 Riser card replacement process

Procedure

  1. Remove the storage node from its cabinet and remove the chassis cover. For details, see Basic Operations.
  2. Remove the PCIe card from the riser card.

    1. Lift the riser card tray, as shown in the following figures.

    3. Rotate the PCIe card latch to open it, as shown in step 2 in Figure 19-12.
    4. Pull out the PCIe card, as shown in step 3 in Figure 19-12.

  3. Remove the riser card.

    1. Loosen the screw on the riser card, as shown in step 1 in Figure 19-13.
      Figure 19-13 Removing a riser card
    2. Pull the riser card in the arrow direction to remove it, as shown in step 2 in Figure 19-13.

  4. Place the removed riser card in an ESD bag.
  5. Take the spare riser card out of its ESD bag.
  6. Install the riser card.

    1. Push the riser card in the arrow direction until it does not move, as shown in step 1 in Figure 19-14.
      Figure 19-14 Installing a riser card
    2. Tighten the screw on the riser card, as shown in step 2 in Figure 19-14.

  7. Install the PCIe card on the riser card.

    1. Insert the PCIe card into the PCIe slot, as shown in step 1 in Figure 19-15.
      Figure 19-15 Installing a PCIe card on the riser card
    2. Close the latch on the PCIe slot, as shown in step 2 in Figure 19-15.
    3. Install the riser card tray, as shown in the following figures.

      Figure 19-17 Installing the riser card tray of a TaiShan 5280 node

  8. Install the chassis cover and put the storage node into the cabinet. For details, see Basic Operations.
  9. 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.
  10. Check whether the riser card is successfully installed.

    Log in to the iBMC page on the storage node. Choose Information > System Info > Other Devices. Query the information about the corresponding part and check whether the installation is successful.
    • If information about the riser card is displayed on the iBMC page, the riser card is successfully installed.
    • If information about the riser card is not displayed on the iBMC page, the riser card fails to be installed. Reinstall it. If information about the riser card still cannot be obtained, contact Huawei technical support.

  11. 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.
