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
system-management I/O port. This port can be used to
attach a modem that is dedicated to communication with
the Netfinity Advanced 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 Capability Port (ECP). (See “Input/output
connectors and expansion slots” on page 209 for the
location of the connector.)

The following table shows the pin-number assignments for
the parallel-port connector.
