Connecting Power to an AC-Powered M320 Router


Each power supply must be connected to a dedicated AC power feed and a dedicated 15 A (250 VAC) circuit breaker. For information about AC power specifications, see M320 AC Power Electrical Specifications.

To connect the AC power cords to the router, attach the power cords from each AC power source to the AC appliance inlet on the faceplate of each power supply (see Figure 1):

  1. Locate the power cords shipped with the router, which should have a plug appropriate for your geographical location (see M320 AC Power Cord Specifications).
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Verify that the source power cabling and the grounding cabling are correct, that they are not touching or blocking access to router components, and that they do not drape where people could trip on them.
  4. Switch the power switch on the power supply faceplate to the off position (O).
  5. Insert the appliance coupler end of a power cord into the appliance inlet on the power supply faceplate.
  6. Remove the cable restraint from the right edge of the power supply faceplate by removing its retainer screw.
  7. Wrap the cable restraint around the power cord, then slide it along the power cord to a position that enables you to reinstall it in the power supply faceplate.
  8. Reinstall the cable restraint by tightening its retainer screw partway into the power supply faceplate.
  9. Carefully pull the AC power cord through the cable restraint until you have the desired amount of slack in the power cord.
  10. Tighten the cable restraint retainer screw to hold the power cord in place.
  11. Insert the power cord plug into an AC power source receptacle. Verify that the power cord does not block access to router components or drape where people could trip on it.
