LED Mode Select Button and Indicator LEDs
To optimize the amount of information displayed for each of the switch ports
without overwhelming you with LEDs, the Switch 2510G Series devices use
two LEDs for each port. The operation of these LEDs is controlled by the LED
Mode select button, and the current setting is indicated by the LED Mode
indicator LEDs near the button. Press the button to step from one view mode
to the next.
