Serial port

The system board provides a serial port on the rear of the chassis to enable out-of-band management. Use the serial port to 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 53).

The serial cable that Nortel supplies with the VPN Router 2750 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 (Figure 28 on page 80).
