Console cable
The console cable is an 8-core shielded cable. The RJ-45 connector at one end of the cable is for the
console port of the switch, and the DB-9 female connector at the other end is for the serial port on a
configuration terminal, as shown in Figure 61 .

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).
