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 5300xl 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. Press the button to change from one mode to the next.
Figure 1-7. Example Mode Select button and Mode LEDs
■
If the Activity 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 indicator LED is lit, the port Mode LEDs light for
those ports that are operating in full duplex.
■
If the maximum speed indicator LED is lit, the port Mode LEDs light
for those ports that are operating at their maximum possible link speed,
for example 1000 Mbps on a 100/1000-T port.
■ If the attention indicator LED is lit, each Mode LED lights briefly for
each network event that might require operator attention, for example,
late collisions or CRC errors. See chapter 4, “Troubleshooting” for more
information.
