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.

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.

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:
