Accessing the switch for the first time
The following options are available for connecting the switch to a configuration terminal:
•
Use a serial console cable to connect the serial console port on the switch to a configuration
terminal.
•
Use a mini USB console cable to connect the mini USB console port on the switch to a
configuration terminal.
As a best practice, use a serial console cable for switch configuration. The switch is provided with a
console cable.
No mini USB console cable is provided with the switch. To use a mini USB console cable for switch
configuration, prepare this cable yourself.
Connecting the serial console cable
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 an 8-core 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 console terminal.
