Installing a Power Module

Installing a Power Module


Each router is configured with one power module by default. When you purchase another power module for a router, follow the instructions in this section to install the power module.

  • AC and DC power modules cannot be used together in the same router.
  • A power module can be hot swapped.
  • Vacant slots in the router must be covered with filler panels.

Tools and Accessories

  • ESD wrist strap
  • Phillips screwdriver


  1. Wear an ESD wrist strap. Ensure that the ESD wrist strap is grounded and in a close contact with your wrist.
  2. Loosen the captive screw on the filler panel and remove the filler panel.
  3. Install a power module in the router.
    1. Rotate the ejector levers on the power module outward and slide the power module into the slot along the guide rails until the power module is completely attached to the router panel.
    2. Rotate the ejector levers inward to lock the power module in the slot.
    3. Use a Phillips screwdriver to tighten the captive screws on the power module.
