Troubleshooting
This chapter contains suggestions on how to troubleshoot problems with
the switch.
Note
For further assistance, please contact Allied Telesis Technical

Problem 1:
The unit is not receiving power. All the port LEDs and Switch
ID LED are off, and the fans are not operating.
Solutions:
Try the following:
Verify that the power cord is securely connected to the power
source and AC connector on the back panel of the switch.
Verify that the DC power wires are securely connected to the
screws on the front panel and to the DC power source unit.
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. The power requirements for the switch are
listed in “Power Specifications” on page 268.
Try replacing the power supply.
Note
Power supplies are hot swappable. If the chassis has two power
supplies and one fails, you can replace the failed unit without having
to power off the operational power supply.
Problem 2:
All the port LEDs are off even though the ports are connected
to active network devices.
Solution:
The switch might 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 can also toggle the LEDs off and on with the ECOFRIENDLY LED and
NO ECOFRIENDLY LED commands in the command line interface.
