Problem 1: The POWER LED on the front of the switch is off.

Solutions: The unit is not receiving power. Try the following:

„Verify that the power cord is securely connected to the power source and to the AC connector on the back panel of the switch.

„Verify that the power outlet has power by connecting another device to it.

„Try connecting the unit to another power source.

„Try a different power cord.

„Verify that the voltage from the power source is within the required levels for your region.

Problem 2: A twisted pair port on the switch is connected to a network device but the port’s LINK/ACT LED is off.

Solutions: The port is unable to establish a link to a network device. Try the following:

„Verify that the network device connected to the twisted pair port is powered on and is operating properly.

„Verify that the twisted pair cable is securely connected to the port on the media converter channel and to the port on the remote network device.

„Verify that the port is connected to the correct twisted pair cable. This is to eliminate the possibility that the port is connected to the wrong network device, such as a powered off device.

„Try connecting another network device to the twisted pair port with a different cable. If the twisted pair port is able to establish a link, then the problem is with the cable or the other network device.

„Verify that the twisted pair cable does not exceed 100 meters (328 feet).

„Verify that you are using the appropriate category of twisted pair
