3.2. About LED modes

3.2.1. Indicator modes and switching between them

This product offers the following two indicator modes.

Mode name Function Overview

LINK/ACT mode

The LINK/ACT LED indicates the link status, the SPEED LED indicates the connection speed, and the PoE STATE LED indicates the power supply status.

OFF mode

The LINK/ACT LED, SPEED LED, and PoE STATE LED turn off to reduce power consumption.

The indicator mode can be switched using the LED MODE button.
The flowchart below shows how to switch the indicator mode.

  • Switching the indicator mode (when the default LED mode is the LINK/ACT mode)

3.2.2. LED indication for OFF mode

When the LED mode is in the OFF mode, all the LINK/ACT LED, SPEED LED, and PoE STATE LED turn off regardless of the link status, loop detection status, and PoE power supply status.

3.2.3. Changing the LED mode after system startup

This product enables the LED mode after system startup (the default LED mode) to be changed.
The initial default LED mode is set to LINK/ACT mode, but it can be changed using the led-mode default command.

You can check the default LED mode and the currently displayed LED mode using the show led-mode command.

3.3. Other LED indications

When you turn on the power while holding down the LED MODE button and keep that state for approximately 10 seconds, all port LEDs turn orange regardless of the LED mode status and return to the factory default settings.
