Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
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: All of the port LEDs are off even though the ports are
connected to active network devices.
Solution: The switch is probably operating in low power mode. To toggle
on the LEDs, press the eco-friendly button on the front panel.
Caution
Pressing the eco-friendly button for more than 4 seconds causes the
switch to reboot. The switch does not forward network traffic during
the reboot process. Some network traffic may be lost. Pressing the
eco-friendly button for more than 10 seconds causes the switch to
reset to factory defaults.
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 network device connected to the twisted pair port is
powered on and is operating properly.
