Connecting Power to an AC-Powered MX480 Router

Caution: Do not mix AC and DC power supplies within the same router. Damage to the router might occur.

You connect AC power to the router by attaching power cords from the AC power sources to the AC appliance inlets located on the power supplies. For power cord and AC power specifications, see AC Power Cord Specifications for the MX480 Router.

To connect the AC power cords to the router (see Figure 1):

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.
2. Locate the power cords shipped with the router, which should have a plug appropriate for your geographical location (see AC Power Cord Specifications for the MX480 Router).
3. Move the AC input switch next to the appliance inlet on the power supply to the off (O) position.
4. Connect the power cord to the power supply.
5. Insert the power cord plug into an external AC power source receptacle.

   Note: Each power supply must be connected to a dedicated AC power feed and a dedicated external circuit breaker. We recommend that you use a 15 A (250 VAC) minimum, or as required by local code.

6. Route the power cord along the cable restraint toward the left or right corner of the chassis. If needed to hold the power cord in place, thread plastic cable ties, which you must provide, through the openings on the cable restraint.
7. Verify that the power cord does not block the air exhaust and access to router components, or drape where people could trip on it.
8. Repeat Step 2 through Step 6 for the remaining power supplies.
