3.3.2 Connection Procedure
When you want to use the terminal to configure the switch, follow these steps to connect a
terminal device to the switch using the console cable:
1) Plug the DB-9 female connector of the console cable to the serial port of the console
terminal or PC.
2) Connect the RJ-45 connector of the console cable to the console port of the switch.
CAUTION:
Pay attention to the mark on the console port and be sure to plug the connector to the correct port.

NOTE:
 A serial port of a PC and a terminal do not support hot swapping. When connecting a PC to a powered-on
switch, you are recommended to connect the DB-9 connector of the console cable to the PC before
connecting the RJ-45 connector to the switch.
 When disconnecting a PC from a powered-on switch, you are recommended to disconnect the DB-9
connector of the console cable from the PC after disconnecting the RJ-45 connector from the switch.
