Front of the Switch

LED Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the
switch ports, the Switch 4200vl Series 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. The default Mode LED position is Activity (Act). Press
the button to change from one mode to the next. After ten minutes, the Mode
button setting reverts back to the default setting. The Mode Select button and
LEDs are the same for all the Switch 4200vl Series. The following example is
of a J8772A, 4202vl-72.

If the Activity (Act) indicator LED is lit, each port Mode LED displays
activity information for the port—it flickers as network traffic is received
and transmitted through the port.
If the Full Duplex (FDx) indicator LED is lit, the port Mode LEDs light for
those ports that are operating in full duplex.
If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows
to indicate the connection speed for the port:
• Off = 10 Mbps
• Flashing = 100 Mbps
• On = 1000 Mbps
If the attention (!) indicator LED is lit, each Mode LED lights briefly for
each network event that could require operator attention, for example,
late collisions or CRC errors.
