Replacing a Data Switch

Replacing a Data Switch

This section describes how to replace a data switch.

Impact on the System

During the replacement of a switch, the switch is powered off and all I/O forwarding workload is transferred to another switch, degrading the system reliability.

Prerequisites

  • The spare part of the data switch is ready.
  • The data switch to be replaced has been located.
  • The cable connection position on the data switch to be replaced has been clearly marked.
  • The data switch to be replaced has been powered off.

Precautions

Remove or insert a data switch module with even force. Excessive force may damage the appearance or connectors of the data switch.

Tools and Materials

  • Phillips screwdriver (M3 to M6)
  • ESD wrist strap
  • ESD bag
  • ESD table
  • Labels

Procedure

  1. Check status before replacement.

    1. Check system status.

      Start SmartKit and choose Home > Storage > Routine Maintenance > Health Check. On the Health Check page, perform inspection as instructed. For details, see Checking System Status.

      NOTE:

      If some items fail in the inspection, rectify the faults by performing the recommended actions in the inspection reports. Ensure that all other parts except the parts to be replaced are working properly.

    2. Check the status of the parts to be replaced.

      Start SmartKit and choose Home > Storage > Parts Replacement > Parts Replacement. On the Parts Replacement page, click FRU Replacement. Then complete the check before the replacement as prompted. For details, see Replacing an FRU.

    You can proceed to next steps only when all items pass the pre-replacement check and the replacement page is displayed. If any item fails, rectify the fault as prompted.

  2. Wear an ESD wrist strap.
  3. Remove cables connected to the data switch that you want to replace.

    NOTE:

    For the ground cable of the data switch, you only need to remove the end that connects to the cabinet in this step. (The other end of the cable is secured to a side of the data switch and will be removed after the data switch is removed from the cabinet.)

  4. Remove the data switch from its cabinet, as shown in Figure 6-207.

    1. Use a Phillips screwdriver to remove the M6 screws from the data switch's mounting ears.
    2. Pull the data switch out of the cabinet along guide rails and place it on the ESD table.
    Figure 6-207 Removing a data switch

  5. Remove the ground cable and mounting ears from the data switch, as shown in Figure 6-208.

    1. Use a Phillips screwdriver to remove the ground cable from the data switch.
    2. Use a Phillips screwdriver to remove the mounting ears from both sides of the data switch.
    Figure 6-208 Removing the ground cable and mounting ears

  6. Take the spare data switch out of the ESD bag and place it on the ESD table.
  7. Install the ground cable and mounting ears on the spare data switch, as shown in Figure 6-209.

    1. Use a Phillips screwdriver to install the ground cable on a side of the data switch.
    2. Use a Phillips screwdriver to install the mounting ears on both sides of the data switch.
    Figure 6-209 Installing the ground cable and mounting ears

  8. Place the data switch to be installed in the cabinet, as shown in Figure 6-210.

    1. Slide the data switch into the cabinet along the guide rails.
    2. Use M6 screws to secure the data switch in the cabinet.
    3. Verify that the data switch is horizontally installed and firmly secured.
    Figure 6-210 Installing a data switch

  9. Connect cables to the data switch and power it on.
  10. After the Power indicator is steady on, check whether each component is working properly.

    • If working properly, it indicates that the data switch is successfully installed.
    • If not working properly, it indicates that cable connections are incorrect, components are incorrectly installed, or the data switch is faulty.

  11. Confirm the replacement.

    1. Perform a post-replacement inspection.

      After the parts replacement, return to the SmartKit page and click Replaced. Then complete the parts check after the replacement as prompted.

    2. Check system status.

      On the Parts Replacement page, click Inspection to check the system status again. If any inspection item fails, rectify the fault based on the suggestions.

    3. After the preceding procedure is complete, check services on the host for any storage-related error.

Follow-up Procedure

  • After the replacement is complete, label the replaced data switch to facilitate subsequent operations.
  • For details about how to configure the IP address, see Installation Guide of the appropriate version.
