LED Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the
switch ports, the Series 8212zl Switch uses 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.
