Installing options 63• One keyboard port• One auxiliary pointing device (mouse) port• Two serial ports• Two Universal Serial bus (USB) ports• One Ethernet portParallel portThe server has one parallel port. This port supports threestandard Institute of Electrical and Electronics Engineers(IEEE) 1284 modes of operation: Standard Parallel Port(SPP), Enhanced Parallel Port (EPP), and Extended Capa-bility Port (ECP).Viewing or changing the parallel-portassignmentsYou can use the built-in Configuration/Setup Utility programto configure the parallel port as bidirectional; that is, so thatdata can be both read from and written to a device. In bidi-rectional mode, the server supports the ECP and EPPmodes.To view or change the parallel-port assignment:1. Restart the server and watch the monitor screen.2. When the message Press F1 for Configura-tion/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 toadvance through the settings available.Note: When you configure the parallel port as bidirec-tional, use an IEEE 1284-compliant cable. Themaximum length of the cable must not exceed 3meters (9.8 feet).5. Select Save Settings; then, select Exit Setup to exitfrom the Configuration/Setup Utility main menu.Parallel port connectorThe following table shows the pin-number assignments forthe 25-pin, female D-shell parallel-port connector on the rearof the server.Table 7.
