The router will power on and run a series of bootup tests, indicated by blinking LEDs.
Verify AC Power Connection
After you connect the router to AC power, verify that the power is being supplied to the router by checking the status of
the SYS (System) LED. As the router starts up, the SYS LEDs show these states:
For the SYS LED location, see Figure 1 on page 86 in Router LED Locations and States, page 85 .
Connect to DC Power (Optional)
You can connect the router to a DC power source that provides backup power to the router in cases when AC power is
disrupted or fails. You must provide the DC power source and ensure that it is compliant with the installation site
requirements.
Note: The AC power connection mating connector shipped with the router is a 2-way screw terminal printed circuit board
plug connector manufactured by Phoenix Contact (part number 1912184).
To connect a DC-input power source to the router, follow these steps:
1. Turn off power to the DC power source at the designated circuits.
