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
• Two Ultra3 SCSI ports
• One keyboard port
• One auxiliary pointing device (mouse) port
• Two serial ports
• Two Universal Serial Bus (USB) ports
• One Ethernet port
• One Advanced System Management port
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 parallel-port
assignments
You can use the built-in 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:
1. Restart the server and watch the monitor screen.
2. When the message
Press F1 for Configuration/Setup
appears, press F1.
Note: The Devices and I/O Ports choice appears only on the full configuration
menu. If you set two levels of passwords, you must enter the
administrator password to access the full configuration menu.
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 settings
available.
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.
Parallel port connector
The following table shows the pin-number assignments for the 25-pin, female D-shell
parallel-port connector on the rear of your server.
