LED Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the
switch ports, the 5400 zl switches use a Mode LED for each port. The operation
of this LED is controlled by the LED Mode Select button on the switch chassis,
and the current selection is indicated by the mode indicator LEDs near the
button. Press the button to change from one mode to the next.
