CAUTION:

• 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.

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 console terminal.
