Before invoking the console program, be sure to find a null modem cable and use it to
connect from this product’s COM port to your computer’s COM port. Then, execute a
terminal program, such as the Hyper Terminal of MS Windows 95. The connection
parameters should be set to 19200 8-N-1. Be sure to reboot the SMC7004BR. When the

should be some messages, and console prompt ">" appears in the terminal.
In the console mode, you may reset the IP address and the system password of this product.
