To connect a terminal (for example, a PC) to the switch:
1) Plug the DB-9 female connector of the console cable to the serial port of the PC.
2) Connect the RJ-45 connector to the console port of the switch.

NOTE:
 Identify the mark on the console port and make sure you are connecting to the correct port.
 The serial ports on PCs do not support hot swapping. If the switch has been powered on, connect the
console cable to the PC before connecting to the switch, and when you disconnect the cable, first
disconnect from the switch.
