Replacing an AC Power Module

Replacing an AC Power Module

This section describes how to replace an AC power module.

Impact on the System

In the process of replacing a power module on an SVP, if the redundant power supply on the SVP fails unexpectedly, the SVP will be powered off. As a result, all services running on the SVP will be interrupted.


  • The spare part of the power module is ready.
  • If the SVP has two power modules configured, you can remove one power module without powering off the SVP. Before removing the power module, make sure that the other power module is working properly and its power rating is greater than or equal to the rated power of the whole SVP.
  • You have determined the position on the SVP for removing a power module.
  • You have obtained the rack number and chassis number of the SVP.
  • You have located the SVP based on the preceding information, and labeled its panel to prevent misoperations.


  • Do not touch the connectors of a power module and a power cable.
  • Remove and insert a power module with even force. Excessive force may damage the appearance or connectors of the power module.
  • Remove only one power module at a time.
  • Shorten the duration of replacing a power module as much as possible.

Tools and Materials

  • ESD gloves or ESD wrist strap
  • Packaging materials, for example, an ESD bag
  • Labels


  1. Wear an ESD wrist strap.
  2. (Optional) If only one power module is configured, power off the SVP.
  3. Open the cable tie for the power cable. See Figure 6-220.

    Figure 6-220 Opening a cable tie

  4. Remove the power cable from the power module to be replaced. See Figure 6-221.

    Figure 6-221 Removing a power cable

  5. Press the spring on the power module in the arrow direction. Hold the handle and pull the power module out of the slot. See steps (1) and (2) in Figure 6-222.

    Figure 6-222 Removing a power module

  6. Place the removed power module in an ESD bag.
  7. Take the spare AC power module out of the ESD bag.
  8. Push the spare AC power module along the guide rails into a slot until you hear a click.

    The power module spring snaps into the latch so that the power module is secured. See Figure 6-223.

  9. Connect the power cable to the power module. See Figure 6-224.

    Figure 6-224 Connecting a power cable to an AC power module

  10. Secure the power cable using a cable tie. See Figure 6-225.

    Figure 6-225 Securing a power cable

  11. Wait about two minutes and check the status of the Running indicator on the power module to determine whether the power module is successfully installed. Figure 6-226 shows the location of the Running indicator.

    • If the indicator is steady green, the power module is successfully installed.
    • If the indicator is steady off, the newly installed power module is faulty, the power module slot is faulty, or the power module is incorrectly installed.

Follow-up Procedure

Label the replaced power module to facilitate subsequent operations.
