Replacing a Riser Card

Replacing a Riser Card

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

Impact on the System

Before replacing a riser 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 riser card is ready.
  • The faulty riser card has been located.

Precaution

  • Only professional technical support engineers are allowed to replace a riser card.
  • A storage node has two power modules. Ensure that both are disconnected.

Tools and Materials

  • Flat-head screwdrivers
  • 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 5-227.

    2. Pull out the storage node along the guide rails away from the cabinet, as shown in step 2 in Figure 5-227.
    3. Push the release button upward, and remove the storage node with the inner rails. See Figure 5-228. 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 5-229.
    2. Open the ejector lever to push the enclosure cover backwards, as shown in step 2 in Figure 5-229.

  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 5-231.

    2. Rotate the PCIe card latch to open it, as shown in step 2 in Figure 5-231.
    3. Pull out the PCIe card, as shown in step 3 in Figure 5-231.
  8. Place the removed riser card in the ESD bag.
  9. Take the spare riser 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 5-232.

    2. Close the latch, as shown in step 2 in Figure 5-232.
  11. Install the riser card tray and tighten the screw, as shown in Figure 5-233.

  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 5-234.

    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 5-234.
  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 5-235. Note that four people are required to lift 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 5-236.

    3. Tighten the captive screws on the mounting ears to secure the storage node, as shown in Figure 5-237.

  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 GUI 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 riser card is displayed on the iBMC page, the riser card is successfully installed.
    • If the riser card is not displayed on the iBMC page, the replacement riser card may not be properly installed. You need to reperform 2 to 15. If there is still no information about the riser card, contact Huawei technical support.

  16. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 V5 Routine Maintenance.

    • If all inspection items are successful: The inspection is successful.
    • If some inspection items fail the inspection: The inspection is failed. Rectify the faults by taking recommended actions in the inspection reports. You need to reperform inspection after rectifying. If the inspection is still failed, contact Huawei technical support.

Follow-up Procedure

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