Connecting your switch to the network
This chapter describes how to connect your switch to a network.
Accessing the switch for the first time
The first time you access the switch you must use a console cable to connect a console terminal, for
example, a PC, to the console port or USB console port on the switch.
Setting up the configuration environment
If both the console port and the USB console port are used, you can only access the switch through the
USB console port.
Console cables
• Console cable connecting the console port on the switch and the serial port on a terminal
The console cable has a crimped RJ-45 connector for connecting to the console port of the switch,
and a DB-9 connector for connecting to the 9-core serial port on the terminal.
Figure 40 shows the console cable and Table 11 shows its pinouts.
