Chapter 1 Product Overview

Cable Side

Console LEDs

The console LEDs show which console port is in use. See Figure 1-6and Figure 1-9for 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.
