IBM 220 manual Input/output ports, Parallel port, Viewing or changing the port assignments

Input/output ports

This section provides information about the input/output (I/O) ports on your server. These ports include the following:

•One parallel port

•One video port

•One keyboard port

•One auxiliary pointing-device (mouse) port

•Two serial ports

•Two Universal Serial Bus (USB) ports

•One SCSI connector

•One Ethernet port

•One communication connector dedicated to the system-management adapter

Notes:

1.You can set an administrator password through the Configuration/Setup Utility program only if the optional system-management adapter is installed in your server.

2.The Devices and I/O Ports choice appears only on the full Configuration/Setup Utility menu. If you have set both levels of passwords (user and administrator), you must type the administrator password to access the full Configuration/Setup Utility menu.

Parallel port

Your server has one parallel port. This port supports three standard Institute of Electrical and Electronics Engineers (IEEE) 1284 modes of operation: Standard Parallel

Port (SPP), Enhanced Parallel Port (EPP), and Extended Capability Port (ECP).

Viewing or changing the port assignments

You can use the Configuration/Setup Utility program to configure the parallel port as bidirectional; that is, so that data can be both read from and written to a device. In bidirectional mode, the server supports the ECP and EPP modes.

To view or change the parallel-port assignment, do the following:

1.Restart the server and watch the monitor screen.

2.When the message Press F1 for Configuration/Setup appears, press F1.

3.From the main menu, select Devices and I/O Ports; then, press Enter.

4.Select the parallel port; then, use the arrow keys to advance through the available settings.

Note: When you configure the parallel port as bidirectional, use an IEEE 1284- compliant cable. The maximum length of the cable must not exceed 3 meters (9.8 feet).

5.Select Save Settings; then, select Exit Setup to exit from the Configuration/Setup Utility main menu.
