1. Make sure the console server is turned off.
2. Plug the power cable into the console server and into a power source.
3. Turn the console server on.

To turn on an ACS with DC power:
DC power is connected to DC-powered console servers by way of three wires: Return (RTN),
Ground (GND) and -48 VDC.
WARNING: It is critical that the power source supports the DC power requirements of your console server. Make
sure that your power source is the correct type and that your DC power cables are in good condition before
proceeding. Failure to do so could result in personal injury or damage to the equipment.
The following diagram shows the connector configuration for DC power.
