Powering the AC Power Supply Module

ATTENTION

Ensure that the ON/OFF switch is set to

“O”

before connecting to the external power source. Failure to observe

this caution could result in

damage

to, and subsequent failure of, the AC power supply module and human life.

To power on the power supply modules:

1. Set the ON/OFF switch to “O”.

2. Connect the female end of the power cord to the AC power connector on the power supply module.

3. Plug the male end on the power cord into the correct voltage AC rack or wall socket.

4. Set the ON/OFF switch to “l”.

5. Check whether or not the power LED is illuminated to see if the power supply module is working.

DC Power Supply Modules

The TRC-190-DC-xx is equipped with a DC power supply in the back of the chassis. When the power supply

module is correctly installed in the back of the chassis, powering on the power supply module will power on the

whole TRC-190-AC.

The DC power supply module includes:

• A DC power module that supports 36 to 70 VDC input and supplies power to the chassis and installed media

converter slide-in modules.

• A DC power connector.

• An ON/OFF switch, which allows the module to supply power to the chassis and slide-in modules when set

to “l”.

• A power LED indicator.

Optional Power Supply Modules

An extra space is available at the right side of the back of the chassis to install an optional power module, the

PWR-190-DC-xx. The specification is the same as the one that comes with the TRC-190-DC-xx chassis.
