The 1400 W DC power supply works with a variety of DC sources. The DC input can vary from
300 W to 7500 W. Refer to the power supply documentation for additional information.
The supervisor engine cannot detect the DC source plugged into the 1400 W DC power supply. If
you are using the 1400 W DC power supply, use the power dc input command to set the DC input
power. For more information on this command, see the
Supply" section on page 7-11.
