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.)

The following table shows the pin-number assignments for
