Power LED is Off
Check the PWR LED on the front of the switch. If the LED is off, indicating
that the unit is not receiving power, do the following:
Make sure the power cord is securely connected to the power source
and to the AC connector on the rear panel of the switch.
Verify that the power outlet has power by connecting another device
to it.
Connect the unit to another power source.
Use a different power cord.
Check that the voltage from the power source is within the required
levels for your region.
