Installing the Contivity 1700
Table 14 provides the 10/100BASE Ethernet port pinouts.
Serial port
The system board provides a serial port on the rear of the chassis to enable
out-of-band management. Using the serial port, you can assign the management
IP address and subnet mask to the newly installed gateway (for more information,
see
Chapter 3, “Configuring the management IP interface,” on page 43 ).
The serial cable provided with the Contivity 1700 is a DB9/DB25-to-DB9/DB25
cable. This cable provides a crossover connection (transmit-to-receive and
receive-to-transmit). The DB9 connector goes into the gateway and the other DB9
or DB25 connector goes into your workstation.
Table 15 provides the multiple DB9/DB25 serial interface cable pinouts.
