Replacing a Power Module

Replacing a Power Module

Context

  • Before replacing a power module, turn off the power switch on the power module, and then turn off the corresponding circuit breaker in the power distribution cabinet to power off the power module.

  • Be careful of the heat on a power module when replacing it.

  • When removing a power module, do not touch the operating power modules with your body or any tools to avoid electric shocks or short circuits.

To replace the power modules in a running switch, take the following measures to avoid impact of the replacement on the running services:

  • If there are empty power slots in the switch, install a new power module in an empty slot first. Remove the power module to be replaced after the new power module starts to work normally. Then replace other power modules one by one.
  • If all the power slots in the switch are occupied, determine whether replacing a power module will affect the running services. It is recommended that you replace the power modules one by one, and replace the next one when the new power module works normally.
NOTE:

The following procedure replaces a vertically installed power module. The procedure for replacing a horizontally installed power module is similar.

Tools

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

Procedure

  1. Find the power module that needs to be replaced.

    Before replacing a power module, determine in which cabinet and chassis the power module is installed, find the power module in the chassis, and attach a label on the panel of the power module to avoid misoperation.

  2. Turn the power switch on the power module to the OFF position, and then turn off the corresponding circuit breaker in the power distribution cabinet to power off the power module.
  3. Wear an ESD wrist strap or a pair of ESD gloves. When wearing an ESD wrist strap, insert the other end to the ESD jack of a device and ensure that the device is reliably grounded.
  4. Remove the power cable from the power module to be replaced.

    Perform the following steps to remove the AC power cable from an AC power module.

    Release the locking strap or locking latch on the AC power module, and then remove the AC power cable. See Figure 13-1.

    Figure 13-1  Removing an AC power cable

    Perform the following steps to remove the DC power cables from a DC power module.

    1. Use a Phillips screwdriver to loosen the screw on the power terminal cover, and then remove the cover. See callout 1 in Figure 13-2.
    2. Loosen the screws on the DC power terminals, take out the DC power cables and screws, and save them for later use. See callout 2 in Figure 13-2.

      NOTE:

      The methods for removing an OT terminal and a JG terminal from a DC power module are the same. An OT terminal is used as an example here.

  5. Remove the power module.

    The S9300&S9300E&S9300X series switches support two types of power modules. One type has a captive screw on the ejector lever, and the other type has a release button on the ejector lever. They are removed in different ways.

    • Method 1
    1. Rotate the Phillips screwdriver counterclockwise to loosen the captive screw on the ejector lever of the power module. See callout 1 in Figure 13-3.
    2. Raise the ejector lever to release the power module from the backplane. See callout 2 in Figure 13-3.
    3. Slowly pull out the power module with one hand and hold the power module with the other hand. See callout 3 in Figure 13-3.

      Figure 13-3  Removing a power module

    • Method 2
  6. Insert the new power module into the power module slot.

    The two types of power modules are installed in different ways, as shown in a and b of Figure 13-4.

    1. Hold the new power module with one hand on the front panel and the other hand under the bottom. Slowly push the power module along the guide rails in the slot, until the power module is completely attached to the backplane. See callout 1 in Figure 13-4.
    2. Lower the ejector lever until it is securely attached to the power module. See callout 2 in Figure 13-4.
    3. (Only for a power module secured with a captive screw) Rotate the Phillips screwdriver clockwise to tighten the captive screw on the ejector lever. See callout 3 in Figure 13-4.

  7. Connect power cables according to Connecting DC Power Cables or Connecting AC Power Cables.
  8. Turn on the corresponding circuit breaker in the power distribution cabinet to power on the new power module.
  9. Verify the functions of the new power module.

    Turn on the new power module and check whether the power module functions normally.

    • Observe the RUN or INPUT status indicator on the power module. If the indicator is steady green, the power module is working normally. If the indicator turns red, the power module does not work normally.

    • Run the display device command to check the running status of the power module.

    If the new power module does not work normally, contact the equipment supplier for technical support.

Follow-up Procedure

After replacing the power module, collect all tools. If the old power module is faulty, fill in the Repair Transmission Sheet and send the faulty module with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
