8. Verify that the mounng 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 locaon. The
chassis has a separate protecve earthing terminal (sized for M6 hex screws) in addion to the power
supply cord's grounding pin. This separate protecve 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 aached 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 nish before grounding connecons are made.
3. Aach an electrostac discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved
site ESD grounding point. See the instrucons for your site.
4. Connect one end of the grounding cable to a proper earth ground, such as the rack.
