Step 5: Connect Power Cables
Depending on your configuration, your router uses either AC or DC power supplies. Perform
the appropriate procedures for each power supply in your router.
WARNING: You must ground the router before connecting either the AC
power cord or the DC power cables.

Connect Power to an AC Router
1. Locate power cords that have a plug appropriate for your geographical location. For
more information, see the MX5, MX10, MX40, and MX80 3D Universal Edge Router
Hardware Guide.
2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
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 customer site circuit breaker. We recommend that
you use a dedicated customer site circuit breaker rated for either
15 A (110 VAC) minimum or 10 A (220 VAC) minimum, or as required by
local code.
6. Dress the power cord appropriately. Verify that the power cord does not block the air
exhaust and access to router components, or drape where people could trip on it.
7. Repeat Step 1 through Step 6 for the remaining power supply.
8. Switch the AC switch on each power supply to the on position (I) and observe the
status LED on each power supply faceplate. If an AC power supply is correctly installed
and functioning normally, the status LED lights green steadily.
If the status LED indicates that the power supply is not functioning normally, repeat
the installation and cabling procedures.
