Master LED
The Master LED shows the stack master status. Table 2-2 lists the LED colors and
their meanings.
Port LEDs and Modes
Each RJ-45 port and SFP module slot has a port LED. These port LEDs, as a group
or individually, display information about the switch and about the individual
ports. The port modes determine the type of information displayed through the
port LEDs.
Table 2-4 lists the mode LEDs and their associated port mode and
meaning.
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 2-5 explains how to interpret the port LED colors in different
port modes.
If your switches are stacked and you press the Mode button on any one of the
switches in the stack, all the switches in the stack change to display the same
selected mode. For example, if you press the mode button on the stack master to
display SPEED, all the other switches in the stack also display SPEED.
