Port LEDs and Modes
Each Ethernet port, 1-Gigabit Ethernet module slot, and 10-Gigabit Ethernet module slot has a port LED.
These port LEDs, either as a group, or individually, display information about the switch and the
individual ports. The port mode determines the type of information shown by the port LEDs. Table 1-3
lists the mode LEDs and their associated port modes and meanings.
To select or change a mode, press the Mode button until the desired mode is highlighted. When you
change port modes, the meanings of the port LED colors also change. Table 1-4 explains how to interpret
the port LED colors in different port modes.
When you press the Mode button on any switch in the switch stack, all the stack switches change to show
the same selected mode. For example, if you press the Mode button on the active switch to show the
SPEED LED, all the other switches in the stack also show the SPEED LED.
