Problem 1: The Stack ID 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: All of the port LEDs are off even though the ports are connected to active network devices.

Solution: The switch may be operating in the low power mode. To toggle on the LEDs, press the eco-friendly button on the front panel of the switch. You may also toggle the LEDs off and on with the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in the Global Configuration mode of the command line interface.

Problem 3: 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 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.
