Product Overview
10/100 and 10/100/1000 Ports
Port LEDs and Modes
Each RJ-45 port, SFP module slot, and XENPAK 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 that the port LEDs display.
Table 1-4
lists the mode LEDs and
their associated port modes and meanings.
Table 1-5
lists the PoE LED colors and their 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 1-6
explains how to interpret
the port LED colors in different port modes.
