Series 2300 and

Mode LED Select Button and Indicator LEDs
To optimize the amount of information that can be displayed for each of the
switch ports without overwhelming you with LEDs, the Series 2300 and 2500
switches use a Mode LED for each port. The operation of this LED is controlled
by the Mode LED Select button, and the current setting is indicated by the
Mode LED Select indicator LEDs near the button. Press the button to step
from one mode to the next.
■ If the Activity (Act) indicator LED is lit, each Mode LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■ If the Full Duplex (FDx) indicator LED is lit, the Mode LEDs light for those
ports that are operating in full duplex.
■ If the maximum speed (Max) indicator LED is lit, the Mode LEDs light for
those ports that are operating at their maximum possible link speed: 100
Mbps for 10/100 ports and 100-FX fiber-optic ports, and 1000 Mbps for
100/1000Base-T or gigabit fiber-optic ports.
■
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. See chapter 3, “Troubleshooting” for more
information.
