Serial Interface Cable (Optional) - Nortel 1500 Series Getting Started

Getting Started with the Contivity Extranet Switch 1500 Series

Serial Interface Cable (Optional)

Nortel Networks recommends that you use the IP Address Configuration Utility
diskette for easy initial IP address configuration (refer to page 4-3 for details).
However, Nortel Networks ships a serial cable with the Switch. Optionally, you
can use the Serial Interface to provide the Switch with a Management IP Address,
subnet mask, and default gateway address (refer to page 4-2 for details). Later,
you can use the serial interface configuration menu to perform management
functions that you might need if problems were to arise.
The serial cable provided with the Switch is a DB9/DB25-to-DB9/DB25. This
provides a crossover (transmit-to-receive and receive-to-transmit). The DB9
connector goes into the Switch and the other DB9 or DB25 connector goes into
your workstation. You should ignore the extra DB25 connection that
is attached to the Switch.
