Netfinity 5000 - Serial Port Connectors

Applicable to: World-Wide

Serial Port Connectors
Serial ports are used to communicate with printers, plotters, external modems, auxiliary terminals, and other computers. Your server provides two serial ports (A and B), and a special type of serial port (Management Port C). You can add more serial ports by installing a serial adapter in one of the expansion slots.

Note Serial port A can be shared by the system management processor and operating system. Serial port B is used by the operating system only. Management port C is controlled exclusively by the system management processor, cannot be used by the operating system, and cannot be configured using the Configuration/Setup Utility program. See the Advanced System Management Information section of this Server Library for information about configuring serial ports A and C.

Serial ports transfer data asynchronously; they can transmit any number of bits at any time, with no restriction on the duration of the pauses between characters. The serial ports transmit and receive data and commands at a rate of 300 bits per second (bps) up to 115 200 bps.

The bits-per-second measurement is commonly referred to as the baud rate. Each of the two serial connectors provided on your Netfinity 5000 uses a 9-pin, D-shell connector.

Table 10 shows the pin-number assignments for the serial port connectors. The pin-number assignments conform to the industry standard.
