Replacing an Internal Cable

Replacing an Internal Cable

Impact on the System

  • Before replacing an internal cable, 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 internal cable is ready.
  • The faulty internal cable has been located.
  • You have recorded the cable mapping of the device, securely stopped the services, executed a shut-down command in the operating system to power off the storage node, and disconnected the node from power sockets and peripheral devices.

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • 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 2-21.
    2. Press the baffle plate and slide the storage node out of enclosure, as shown in step 2 in Figure 2-21.

  9. Remove the cable to be removed.
  10. Place the removed cable in an ESD bag.
  11. Take a spare cable out of the ESD bag.
  12. Install the spare cable. For details about cable port positions, see Internal Cabling for P12E and Internal Cabling for P25E.
  13. Install fan module brackets in the chassis. See Figure 2-26.

  16. 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 2-29.
    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 2-29.

  17. 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 2-30.
    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 2-30.
    3. Ensure that the storage node is horizontally installed and screwed.

  18. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Then power on the storage node.
  19. 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 cable, label the replaced cable to facilitate subsequent operations.
