If the pinouts for the serial management port do not correspond with the pinouts for the RJ-45 ports on the terminal server, you need to make a crossover cable that takes each pin on the Netra 440 server serial management port to the corresponding pin in the terminal server’s serial port.

TABLE 1-3shows the crossovers that the cable must perform.
