3.3.2 Connecting the Console Cable
Follow these steps to connect a terminal device, a PC for example, to the switch:
Step 1: Plug the DB-9 (female) connector of the Console cable to the serial port of the
PC where the switch is to be configured.
Step 2: Connect the RJ-45 connector of the console cable to the Console port of the
switch.
Caution:
Read the mark for the port to be connected carefully to make sure it is the right port.
Note:
The serial ports on PCs do not support hot swapping. Therefore, do not insert or
remove a serial interface cable from a PC that is connected to a switch with power. In
connecting a PC to the switch, first connect the DB-9 connector of the console cable to
the PC and then the RJ-45 connector to the switch. In disconnecting them, remove the
RJ-45 connector prior to the DB-9 connector.
