Bitsuri IV has four Gigabit external Ethernet ports connected to an internal host port. The other three hosts have external RJ-45 access ports that are connected to three of the ports on the switch.
The switch allows all four hosts to be connected on the same segment, leaving one port available for connection to an external local network on that same segment. Three one foot long LAN patch cables are included.
Of course, all hosts need to be connected on the same segment. The included 1ft RJ-45 cables are used to connect the external facing hosts, leaving one Gbps port open for connection to your network/Internet.
