When you turn on the server, the POST routine assigns the serial ports to specific communication port addresses. Some application programs use only certain ports, and some modems are designed for use only at certain communication port addresses. You might need to use the Configuration/Setup Utility program to change communication port address assignments to resolve conflicts. Management port C: The server has a dedicated systems management I/O port. This port can be used to attach a modem that is dedicated to communication with the system management processor. The connector on the back of the server and the pin-number assignments are the same as for the serial ports. Parallel port: The parallel port usually is used to communicate with printers, and transfers data one byte at a time. The parallel port has a 25-pin, female D-shell connector on the back of the server. It support three standard IEEE 1284 modes of operation: Standard Parallel Port (SPP), Enhanced Parallel Port (EPP), and Extended Capacity Port (ECP). (See "Input/Output connectors and expansion slots" on page 194 for the location of the connector.) 13 1 25 14 The following table shows the pin-number assignments for the parallel-port connector.
