You may turn off the port LEDs to conserve electricity when you are not
monitoring the switch. The LEDs may be toggled with the eco-friendly
button on the front panel of the switch or the ECOFRIENDLY LED and NO
ECOFRIENDLY LED commands in the Global Configuration mode of the
command line interface.
Toggling the LEDs on and off does not interfere with the network
operations of the device. The System LED is always on.

When checking or troubleshooting the network connections to the
ports on the switch, you should always check to be sure that the
LEDs are on by either pressing the eco-friendly button or issuing the
ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the Global Configuration mode of the command line interface.
