Installing an M7i AC Power Cord

To install an AC power cord:

1. Locate a replacement power cord with the type of plug appropriate for your geographical location (see M7i Router AC Power, Connection, and 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. Insert the appliance coupler end of the replacement power cord into the appliance inlet on the power supply faceplate and insert the plug into an AC power source receptacle.
4. Verify that the power cord does not block access to router components or drape where people could trip on it.
5. Press the power switch on the power supply faceplate to the ON ( |) position.

   Note: After powering on a power supply, wait at least 60 seconds before turning it off.

6. If you have only one power supply or the router is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence.

   On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.

   Note: If the Routing Engine finishes booting and you need to power off the router again, see Powering Off the M7i Router. After powering off a power supply, wait at least 60 seconds before turning it back on.

7. Check the LEDs on the power supply faceplate. When the power supply has powered on successfully, the green OUTPUT OK LED lights steadily.

   After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the output status LED on the power supply, the command display output, and messages on the LED display on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

   If the LEDs are not lit in the appropriate pattern after 60 seconds, repeat the procedures to replace the AC power cord.
