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.
