Powering On an AC-Powered MX204 Router
To power on an AC-powered router:
1. Verify that the power supply modules are fully inserted in the chassis.
2. Verify that each AC power cord is securely inserted into its appliance inlet.
3. Verify that an external management device is connected to the CON port on the chassis.
4. Turn on power to the external management device.
5. Switch on the dedicated customer-site circuit breakers for the power supply modules. Follow the
instructions for your site.
6. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on
the chassis.
7. Observe the status LED on each power supply faceplate. If an AC power supply is correctly installed
and functioning normally, the status LED on the router beside the AC power supply lights steadily
green.
If the status LED on the power supply is lit red, the power supply is not functioning normally. Repeat
the installation and cabling procedures.
