3Com Switch 8800 Configuration Guide Chapter 2 Logging into Switch
Chapter 2 Logging into Switch
2.1 Setting Up Configuration Environment Through the Console Port
Step 1: As shown in the figure below, to set up the local configuration environment,
connect the serial port of a PC (or a terminal) to the Console port of the switch with the
Console cable.
RS-232 Serial port
Console port
Console cable
Figure 2-1 Set up the local configuration environment through the Console port
Step 2: Run termin al emulator (such as Terminal on Windows 3X or the Hyper Terminal
on Windows 9X) on the Computer. Set the terminal communication parameters as
follows: Set the baud rate to 9600, databit to 8, parity check to none, stopbit to 1, flow
control to none and select the terminal type as VT100.
Figure 2-2 Set up new connection

Figure 2-4 Set communication parameters
Step 3: The switch i s powered on. Display self-test information of the switch and prompt
you to press Enter to show the command line prompt such as <SW8800>.
Step 4: Input a command to config ure the switch or view the operation st ate. Input a “?”
for an immediate help. For details of specific commands, refer to the following chapters.
