Replacing a front Service Disk Midplane

Replacing a front Service Disk Midplane

This section describes how to replace the front service disk midplane (referred to as the midplane) of the P36/C36.

Impact on the System

Before you replace the midplane, you need to power off the P36/C36. Therefore, the running services on the P36/C36 will be interrupted.

Prerequisites

The midplane to be replaced is ready.

Precaution

  • Only professional maintenance personnel are allowed to replace a midplane.
  • The P36/C36 has two power supplies. Ensure that both supplies are disconnected.
  • To prevent personal injury, arrange two persons to replace it.

Tools and Materials

  • Phillips screwdriver
  • ESD gloves
  • ESD wrist strap
  • ESD bag
  • Labels

Procedure

  1. Wear the ESD wrist strap or gloves. For details, see Wearing an ESD Wrist Strap in Replacing a Main Control Board Enclosure.
  2. Take out the disk enclosure.
    1. Use KVM to log in to the OS as user root (default password is Root@storage), then run poweroff to poweroff the node and wait for the shutdown to complete.

      Wait for the KVM screen to have no output, indicates that the shutdown has been completed.

    2. Label the cables on the P36/C36 and disconnect it from the power socket and other devices.
    3. Move the P36/C36 out of the cabinet to an ESD workbench. For details, see 4 in Replacing a Fan Module in the Main Control Board Enclosure.
    4. Take out the main control board enclosure. For details, see 4 in Replacing a Fan Module in the Main Control Board Enclosure.
    5. Take out the two power modules. For details, see 2 in Replacing a Power Module.
    6. Remove the disk modules. For details, see 2 to 5 in Replacing a Service Disk Module.
    7. As shown in step 1 in Figure 6-23, loosen the 14 screws on the disk enclosure counterclockwise and put the removed screws in an ESD bag.
    8. As shown in step 2 in Figure 6-23, pull out the disk enclosure and put it on the workbench.

  3. Remove the midplane.

    1. As shown in step 1 in Figure 6-24, disconnect the mounting ear cables from the midplane.
    2. As shown in step 2 in Figure 6-24, remove the 15 screws fixing the midplane.
    3. As shown in step 3 in Figure 6-24, hold the power connectors on two sides of the midplane and remove the midplane.
    4. Put the removed midplane into an ESD bag. The operation of removing the midplane is complete.

  4. Install the replacement midplane.

    1. Take the midplane to be installed out of the ESD bag.
    2. As shown in step 1 in Figure 6-25, put the midplane horizontally on the service disk enclosure along the two positioning pins
    3. As shown in step 2 in Figure 6-25, secure the 15 screws fixing the midplane.
    4. As shown in step 3 in Figure 6-25, carefully connect the mounting ear cables to the connector on the midplane, and secure the mounting ear using the plastic parts.

  5. Install the service disk enclosure.
    1. As shown in step 1 in Figure 6-26, gently push the disk enclosure into the P36/C36 enclosure until it snaps into place.
    2. s shown in step 2 in Figure 6-26, fasten the 14 screws on the disk enclosure clockwise.

  6. Install the main control board enclosure. For details, see 11 in Replacing a Fan Module in the Main Control Board Enclosure.
  7. Install the power supply. For details, see 4 in Replacing a Power Module.
  8. Install disks. For details, see 7 in Replacing a Service Disk Module.
  9. Install the P36/C36 into the cabinet. For details, see 15 in Replacing a Fan Module in the Main Control Board Enclosure.
  10. Connect the P36/C36 with the power supply and other devices. Ensure that the cables are connected properly, and then power on the device.
  11. Check whether the midplane has been replaced successfully.

    • If the disk is powered on correctly and the disk indicator is steady on, the midplane has been replaced successfully.
    • If the disk indicator is off, the midplane has failed to be replaced. Reinstall it or contact the technical support engineers of your vendor.

Follow-up Procedure

After the midplane is replaced, label the replaced midplane for the convenience of subsequent handling.
