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. Table 3-3 shows the multiple cable DB-9/DB25
serial interface cable pinouts.
