A-2 APPENDIX A: USING THE CONSOLE PORT
Requirements To use the console port and CLI, you need:
■ A PC with a serial port
■ A null modem cable
■ A terminal-emulation program
If you need to perform a firmware update, the terminal-emulation
program must support one of these file transfer protocols: Xmodem,
Xmodem-1K, or Xmodem-CRC.
Connecting the
Console Port
It is not necessary to disconnect the hub from the power source to
connect the console port. However, if you do disconnect the power,
you can watch POST messages when you reconnect the power.
With Power
Connected
To connect the console port while the hub is connected
to power:
1 Connect a null modem cable between the PC serial port and the console
port on the hub’s rear panel. (See Figure A-1.)
2 Turn on the PC.
3 Start the terminal-emulation program.
4 Configure the program with the same settings as the Hub 1000 SX
console interface port:
■ 9600 baud
■ 8 data bits
■ 1 stop bit
■ No parity
5 Press Enter.
The PC screen displays the CLI header and the password prompt:
