NOTE: Each AC power supply has two AC appliance inlets. Each power
supply must be connected to a dedicated AC power feed. For 100-120
VAC, both inlets are used. For 200-240 VAC, only the top inlet is used. For
information about site power preparations, see “M120 Router Power
Requirements” on page 88. For information about connecting the router
to power and ground, see “Connecting Power to an AC-Powered M120
Router” on page 167.

that the status LED on the power supply faceplate blinks, then lights steadily
approximately one minute after you switch on the power switch.
