This application provides a router. A shielding portion is formed by extending outward an end of a housing where a rotary shaft seat is disposed. The rotary shaft seat is disposed on a side of the shielding portion facing a back of the housing. An end of the shielding portion away from the housing extends to at least a side of the rotary shaft seat away from the housing, so as to shield a front of the rotary shaft seat. In this way, the rotary shaft seat is invisible in a conventional viewing angle, that is, a viewing angle from a front of the router.

One embodiment is directed to a system that comprises a plurality of ports configured to establish a plurality of physical information connections and a plurality of physical scanning connections using cables. Each information connection is associated with a respective scanning connection. Each scanning connection is separate from the respective information connection associated with that scanning connection. The system is configured to selectively transmit a respective scanning signal from each port over a respective one of the scanning connections. The system is configured to selectively receive a respective scanning signal at each port from a respective one of the scanning connections. Connection information is derived from the scanning signals communicated over the scanning connections. Other embodiments are disclosed.
