Replacing the PCIe Card on the Riser Card

Replacing the PCIe Card on the Riser Card

On the riser card, the storage node provides 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.

Prerequisites

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

    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.

Precaution

  • The storage node supports 2-port GE, 4-port GE, 2-port 10GE, 2-port 25GE RoCE, 2-port 40GE RoCE, and 2-port 100Gb IB PCIe cards. C36X nodes also support 10GE PCIe cards with two RJ-45 electrical ports. 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

Procedure

  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. Loosen the captive screws on the storage node panel using a screwdriver, as shown in step 1 in Figure 5-238.

      Figure 5-238  Pulling out a storage node

    2. Pull out the storage node along the guide rails away from the cabinet, as shown in step 2 in Figure 5-238.
    3. Push the release button upward, and remove the storage node with the inner rails. See Figure 5-239. Note that four people are required to lift the storage node.

  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 5-240.
    2. Open the ejector lever to push the enclosure cover backwards, as shown in step 2 in Figure 5-240.

  6. Loosen the screw on the riser card tray and lift the riser card tray, as shown in Figure 5-241.

  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 5-242.

    2. Rotate the PCIe card latch to open it, as shown in step 2 in Figure 5-242.
    3. Pull out the PCIe card, as shown in step 3 in Figure 5-242.
  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 5-243.

      Figure 5-243  Installing a PCIe card on a riser card

    2. Close the latch, as shown in step 2 in Figure 5-243.
  11. Install the riser card tray and tighten the screw, as shown in Figure 5-244.

    Figure 5-244  Installing a riser card tray

  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 5-245.

      Figure 5-245  Installing an enclosure cover

    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 5-245.
  13. Put the storage node into the cabinet.
    1. Lift the storage node, align the inner rails with the holding rails, and push the storage node into the rack. See Figure 5-246. Note that four people are required to lift the storage node.

      Figure 5-246  Installing the storage node

    2. Press the release buttons on both sides, and push the storage node into the cabinet until the storage node cannot move forward, as shown in Figure 5-247.

    3. Tighten the captive screws on the mounting ears to secure the storage node, as shown in Figure 5-248.

      Figure 5-248  Securing a storage node

  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. When the screen shown in Figure 5-249 is displayed during the system startup, press Delete.

      NOTE:
      If a dialog box that informs you of entering the password is displayed, enter the BIOS password (default: Admin@9000).

    2. Choose Security > Clear NvDimm Flash and press Enter, as shown in Figure 5-250.

      Figure 5-250  Choosing Clear NvDimm Flash

    3. In the Clear NvDimm Flash dialog box, select Yes and press Enter, as shown in Figure 5-251.

      Figure 5-251  Starting to clear NVDIMM data

    4. If the Clear NvDimm flash success! message is displayed, data in the NVDIMM is cleared, as shown in Figure 5-252.

      Figure 5-252  NVDIMM data cleared

    5. Press Enter and then F10. In the dialog box that is displayed, select Yes and press Enter to save the configuration and restart the storage node, as shown in Figure 5-253.

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

    • If the PCIe card is displayed on the iBMC page, the PCIe card is successfully installed.
    • If the PCIe card is not displayed on the iBMC page, the replacement PCIe card may not be properly installed. You need to reperform 2 to 17. If there is still no information about the PCIe card, contact Huawei technical support.

Follow-up Procedure

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