CAUTION:
•
Identify the mark on the serial console port and make sure you are connecting to the correct port.
•
The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch,
first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch
end.
A serial console cable is provided with the switch.
A serial console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for
connecting to the serial console port of the switch, and a DB-9 female connector at the other end for
connecting to the serial port on the configuration terminal.
