Note
The twisted pair ports on the switch feature Auto-MDI when operating at either 10, 100, or 1000 Mbps. Each port is individually configured as MDI or MDI-X when connected to an end-node. Consequently, you can use either a straight-through or crossover twisted pair cable when connecting any network device to a twisted pair port on the switch. For example, a port operating at 10 or 100 Mbps uses two pairs of twisted pair wiring while a port operating at 1000 Mbps uses four pairs of twisted pair wiring.
