Replacing the PCIe Card on the Riser Card

Replacing the PCIe Card on the Riser Card

On the riser card, P25E and P12E provide the half-height Peripheral Component Interconnect Express (PCIe) card.

Impact on the System

Before replacing a PCIe card, you must power off the storage node. This will adversely affect the services running on the node. Exercise caution when performing this operation.


  • The replacement PCIe card is ready.
  • The faulty PCIe card has been located.

    If the PCIe card to be replaced is a half-height card, remove the full-height barrier chip and install it to the PCIe card.


  • The storage node supports 2-port 10GE, 2-port GE, 2-port 25GE, 2-port 100Gb IB, and 4-port GE PCIe cards. Methods to replace these types of PCIe cards are the same.
  • Only professional technical support engineers are allowed to replace a PCIe card.
  • A storage node has two power modules. Ensure that both are disconnected.
  • If the PCIe card is an IB card or RoCE card, the system automatically checks the firmware version of the new PCIe card after the replacement. If the firmware version does not match the OFED version installed on the device, the system automatically upgrades the firmware of the PCIe card. After the upgrade is complete, the device will restart.

Tools and Materials

  • Phillips screwdrivers
  • Electrostatic discharge (ESD) gloves
  • ESD wrist straps
  • ESD bags
  • Labels


  1. Wear an ESD wrist strap or ESD gloves.
  2. Use the KVM to log in to the operating system of the node, enter user name root and its password (default: Root@storage), and run poweroff command to power off the node.

    Wait until the KVM has no output. The power-off is complete.

  3. Remove all power cables and external signal cables.
  4. Remove the storage node from the enclosure.
    1. Slide the storage node out of the cabinet, as shown in step 1 in Figure 2-177.
    2. Press the baffle plate and slide the storage node out of enclosure, as shown in step 2 in Figure 2-177.

  5. Remove the enclosure cover.
    1. Use a flat-head screwdriver to loosen the latch that secures the ejector lever of the enclosure cover, as shown in step 1 in Figure 2-178.
    2. Open the ejector lever to push the enclosure cover backwards, as shown in step 2 in Figure 2-178.

  6. Remove the riser card tray. For details, see 6 in Replacing a Riser Card.
  7. Remove the PCIe card on the riser card.
    1. Horizontally push the latch of the PCIe card outward to unlock it, as shown in step 1 in Figure 2-179.

    2. Rotate the PCIe card latch to open it, as shown in step 2 in Figure 2-179.
    3. Pull out the PCIe card, as shown in step 3 in Figure 2-179.
  8. Put the removed PCIe card into an ESD bag.
  9. Take the replacement PCIe card out of its ESD bag.
  10. Install the PCIe card.
    1. Insert the PCIe card into the PCIe slot, as shown in step 1 in Figure 2-180.

      Figure 2-180  Installing a PCIe card

    2. Install the PCIe card on the riser card, as shown in step 2 in Figure 2-180.
  11. Install the riser card tray. For details, see 7 in Replacing a Riser Card.
  12. Install the enclosure cover.
    1. Place the enclosure cover horizontally, align it with the fixing slots on both side panels of the enclosure, and close the ejector lever, as shown in steps 1 and 2 in Figure 2-181.
    2. Use a flat-head screwdriver to tighten the latch in order to secure the ejector lever of the enclosure cover, as shown in step 3 in Figure 2-181.

  13. Put the storage node into the cabinet.
    1. Align the securing holes in the inner rails with the positioning pins on the storage node, and secure the inner rails to the storage node, as shown in step 1 in Figure 2-182.
    2. Align the inner rails with the holding rails, and push the storage node into the holding rails, as shown in step 2 in Figure 2-182.
    3. Ensure that the storage node is horizontally installed and screwed.

  14. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Then power on the storage node.
  15. Log in to the storage node using the KVM.
  16. Clear NVDIMM data.
    1. Press Delete repeatedly when the screen shown in the following figure is displayed during server startup.

      Figure 2-183  BIOS startup screen

    2. Enter a BIOS password as prompted. The screen for setting the BIOS is displayed.


      The default BIOS password is Huawei12#$ for the French or American keyboard and is Huawei12£$ for the English keyboard.

      To ensure system security, you are advised to change the default BIOS password after the first login.

    3. Choose Security > Clear NvDimm Flash.

      Figure 2-184  Choosing Clear NvDimm Flash

    4. In the Clear NvDimm Flash? dialog box, select Yes and press Enter.

      Figure 2-185  Starting to clear NVDIMM data

    5. Wait 20 seconds. Check whether the displayed dialog box states "Clear NvDimm flash success. Please reboot system!"

      • If yes, go to 16.f.
      • If no, contact technical support.

    6. Press Enter and then F10. In the dialog box that is displayed, select Yes to save the configuration and restart the storage node.

      Figure 2-187  Saving the configuration and restarting the storage node

  17. Log in to the WebUI of the iBMC storage node, and choose Information > Component Information to query the information about corresponding components and check whether the replacement succeeds.

    • If the PCIe card is in the Normal state, the PCIe card is successfully installed.
    • If the PCIe card is in the Fault state, the replacement PCIe card may not be properly installed. Remove the replacement PCIe card and install it again.

Follow-up Procedure

After replacing the PCIe card, label the replaced PCIe card to facilitate subsequent operations.
