Chapter 1 Product Overview
Cable Side
Console LEDs
The console LEDs show which console port is in use. See
Figure 1-6
and
Figure 1-9
for the LED
locations.
If you connect a cable to a console port, the switch automatically uses that port for console
communication. If you connect two console cables, the USB console port has priority.
Port LEDs
RJ-45 ports and SFP-module slots have port LEDs. Port LEDs, as a group or individually, provide
information about the switch and about the individual ports.
