Problem 1: All the port LEDs and Switch ID LED are off, and the fans are
not operating.
Solutions: The unit is not receiving power. Try the following:
Verify that the power cord is securely connected to the power
source and 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. The power requirements for the switch are
listed in “Power Specifications” on page 249.
Problem 2: All of 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.
