FIGURE 1-5 Patch Panel Connection Between a Terminal Server and a Netra 440 Server

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