Connecting Power to an AC-Powered Router

Follow these steps to connect the AC power cords to the router.
Note Connect each AC power supply to a dedicated power source (branch circuit). Each AC input power supply
operates at a nominal input level of 200 to 240 VAC. For more information on AC power input levels, see
Power Connection Guidelines, on page
Procedure
Step 1
Check that the power switch is set to the STANDBY (0) position.
• On version 1 power trays, this switch is at the rear of the power tray.
• On version 2 and version 3 power trays, this switch is at the front of the power tray.
Step 2 Check that the circuit breaker assigned to the AC power source you are connecting is set to OFF.
Step 3
Connect the permanent ground connection (central office grounding system) to the NEBS grounding location
on the router chassis.
Caution
Step 4
Plug the AC power cord into the receptacle at the rear of the AC power tray (see the figure Typical AC Power
Connections to an AC Power Tray Version 1 Power System for the version 1 power tray and see figure
Typical AC Power Connections to an AC Power Tray Version 2 and Version 3 Power System for the version
2 and version 3 power tray).
Step 5
Close the retainer bracket to secure the AC power cord plug to the version 1 power tray receptacle. For the
version 2 and version 3 power tray, tighten the screw that clamps the AC power cord plug in place.
To ensure that power remains off while you are performing this procedure, lock-out/tag-out the
circuit breaker switch in the off (0) position until you are ready to turn it on.
