Console cable
A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting
to the console port of the switch, and a DB-9 female connector at the other end for connecting to the
serial port on the console terminal.

Ethernet twisted pair cable
An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly transmits
analog signals and is advantageous in transmitting data over shorter distances. The maximum
transmission distance is 100 m (328.08 ft).
