8. Verify that the mounting brackets on each side of the rack are level.

Power On
Now that you've mounted your router in the rack, you're ready to connect it to power.
The AC-powered MX304 router comes with two AC power supplies preinstalled on the rear panel.
WARNING: The router is a pluggable type A equipment installed in a restricted-access location. The
chassis has a separate protective earthing terminal (sized for M6 hex screws) in addition to the power
supply cord's grounding pin. This separate protective earthing terminal must be permanently connected
to earth.
NOTE: Each power supply must be connected to a dedicated AC power feed and a dedicated customer-site
circuit breaker. We recommend using a circuit breaker rated for 15 A (110 VAC) minimum, or as required by local
code.
1. Verify that a licensed electrician has attached the cable lug that ships with the router to the grounding cable.
2. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections are made.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved
site ESD grounding point. See the instructions for your site.
4. Connect one end of the grounding cable to a proper earth ground, such as the rack.
