Replacing Power Modules and Fan Modules

Replacing Power Modules and Fan Modules

Context

  • Power modules and fan modules are hot swappable.
  • Replacing a power module will interrupt services unless the switch is powered by another power module.
  • The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE6857-48S6CQ-EI, CE6863-48S6CQ, CE6820-48S6CQ, and CE6881-48S6CQ) must have two fan modules running to ensure normal operation. If a fan module needs to be replaced, complete the replacement procedure within 3 minutes. Do not remove the two fan modules from the switch simultaneously. The CE6857-48S6CQ-EI, CE6863-48S6CQ, CE6820-48S6CQ, and CE6881-48S6CQ have four fan modules and support 3+1 backup. You are advised to install four fan modules on the switch to ensure normal operation. If a fan module needs to be replaced, complete the replacement procedure within 3 minutes. Do not remove the two fan modules from the switch simultaneously.
  • After a 600 W/1200 W AC&240 V DC power module or a 600 W/1200 W high-voltage DC power module is powered off, it cannot be powered on again until the STATUS indicator on the power module is off.

The procedures for replacing a fan module and a power module are similar. A power module is used as an example to describe the replacement procedure.

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Phillips screwdriver

Procedure

  1. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in close contact with your wrist.
  2. Turn off the power module. (Skip this step if the power module does not have a power switch.)
  3. Remove the power cable from the power module.
    • For a 150 W/350 W/600 W AC power module, perform the following steps to remove the AC power cable:
      1. Release the locking clip on the AC cable locking strap.
      2. Remove the locking strap from the AC power cable.
      3. Remove the AC power cable plug from the power socket on the AC power module.

    • For a 350 W/600 W/1000 W DC power module, perform the following steps to remove the DC power cables:
      1. Press the release buttons at the top and bottom of the DC power cable plug.
      2. Remove the DC power cable plug from the power socket on the DC power module.

    • For a 600 W/1200 W AC&240 V DC power module or 600 W/1200 W high-voltage DC power module, perform the following steps to remove the power cable:
      1. Unbind the velcro strap on the power cable.
      2. Remove the power cable plug from the power socket on the power module.

    • For a 1200 W DC power module, perform the following steps to remove the power cable:
      1. Unbind the velcro strap on the power cable.
      2. Remove the power cable plug from the power socket on the power module.

  4. Remove the power module from the switch.
    • To remove the power module secured by a captive screw, perform the following steps:
      1. Use a Phillips screwdriver to loosen the captive screw on the power module counterclockwise.
      2. Slowly pull the power module out by the handle.

    • To remove the power module secured by a lock, perform the following steps:
      1. Press and hold the lock on the power module rightward with your thumb.
      2. Slowly pull the power module out by the handle.

  5. Install the spare power module in the switch. For details, see Installing Power Modules and Fan Modules.
  6. Connect the power cable to the new power module. For details, see Connecting Power Cables.
  7. Turn on the power module. (Skip this step if the power module does not have a power switch.)
  8. Use either of the following methods to check whether the new power module works normally:

    • If the STATUS indicator on the power module is steady green, the power module works normally. If the STATUS indicator is off, blinking green, or steady red, the power module does not work.
    • Run the display device command to check the running status of the new power module.

Follow-up Procedure

After replacing the power or fan module, collect all tools. If the replaced 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.
