Supplying Power
The DES-1200M is equipped with a universal switching power
supply that accepts AC input voltages from 100 to 240VAC and
50 to 60 Hz.
To supply power to your switch:
1. Plug the connector of the power cord into the power port on
the rear panel of your switch.
2. Plug the other end of the power cord into an AC wall outlet.
3. Set the power switch to ON and verify that the Power LED
is lit. If it is not, check the following:
The power switch is in the ON position.
The power cord is properly connected to the wall outlet and
to the power connection on the switch.
The wall outlet is functional.
Note: Network cable segments can be connected or
disconnected from the switch while the power is on, without
interrupting the operation of the switch.
