Auto-MDI
For port speeds of 10 or 100 Mbps, the ports are auto-MDI. They
automatically configure themselves as either MDI or MDI-X. This feature
allows you to use either straight-through or crossover twisted pair
cables to connect devices to the ports. For port speeds of 1000 Mbps,
you must use a straight through twisted pair cable.

LEDs

The port LEDs on the front panel display port status information. Each
