Installing an M320 AC Power Supply
To install an AC power supply (see Figure 1):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
- Switch the power switch on the AC power supply faceplate to the off position (O).
- Using both hands, slide the power supply into the chassis until you feel resistance.
- Firmly push the power supply into the chassis until it comes to a stop. The power supply faceplate should be flush with any adjacent power supply faceplates.
- Tighten the captive screws on each side of the power supply faceplate to secure the power supply in the chassis.
- Insert the appliance coupler end of a power cord into the appliance inlet on the power supply faceplate.
- Remove the cable restraint from the right edge of the power supply faceplate by removing its retainer screw.
- 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.
- Reinstall the cable restraint by tightening its retainer screw partway into the power supply faceplate.
- Carefully pull the AC power cord through the cable restraint until you have the desired amount of slack in the power cord.
- Tighten the cable restraint retainer screw to hold the power cord in place.
- 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.
- Switch the powers seitch on the power supply faceplate to the on position (|). Verify that the OUTPUT OK status LED on the power supply faceplate blinks, then lights steadily approximately 1 minute after you switch the power switch on.
