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 P36E or C36E 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 P36E or C36E 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 cabinet.
    1. Loosen the captive screws on the panel using a Phillips screwdriver, as shown in step 1 in Figure 3-189.

    2. Slowly pull the storage node out along the guide rails, as shown in step 2 in Figure 3-189.
    3. Press the release buttons on both sides and pull the storage node out of the cabinet along the guide rails, as shown in step 3 in Figure 3-189.
  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 3-190.
    2. Open the ejector lever to push the enclosure cover backward, as shown in step 2 in Figure 3-190.

  7. Remove the riser card.
    1. Remove the PCIe card from the riser card tray.
    2. Unscrew the riser card, as shown in step 1 in Figure 3-192.

    3. Push the riser card in the arrow direction and then remove it, as shown in step 2 in Figure 3-192.
  8. Place the removed riser card in the ESD bag.
  9. Take the spare riser card out of its ESD bag.
  10. Install the riser card.
    1. Put the riser card into the tray. Push the riser card in the arrow direction until the riser card is secured, as shown in step 1 in Figure 3-193.

    2. Screw the riser card, as shown in step 2 in Figure 3-193.
  11. Install the PCIe card on the riser card tray.
  12. Put the PCIe card down on the riser card tray, as shown in Figure 3-194.

  13. 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 3-195.

    2. Tighten the latch to secure the ejector lever of the enclosure cover using flat-head screwdriver, as shown in step 3 in Figure 3-195.
  14. Put the storage node into the cabinet.
    1. Arrange at least four persons to lift the storage node on both sides, align the inner rails on the storage node with the holding rails, and push the storage node into the cabinet along the holding rails, as shown in Figure 3-196.

  15. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Then power on the storage node.
  16. Log in to the GUI of the iBMC storage node, and choose Information > System Info > Expansion Board 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 16. If there is still no information about the riser card, contact Huawei technical support.

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