Serial interface cable

Nortel Networks ships a serial cable with the Contivity to enable configuration of
the Management IP address, subnet mask, default gateway address, and other
configurable parameters. Nortel Networks recommends that you use the IP
Address Configuration Utility diskette for easy initial IP address configuration.
Later, you can use the serial interface configuration menu to perform management
functions.
The serial cable provided with the Contivity is a DB9/DB25-to-DB9/DB25. This
provides a crossover (transmit-to-receive and receive-to-transmit). The DB9
connector goes into the Contivity and the other DB9 or DB25 connector goes into
your workstation.
