Parallel Connector; Viewing Or Changing The Connector Assignments - IBM xSeries 200 Hardware Maintenance Manual

Parallel connector

The server has one parallel connector. This connector 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 connector assignments

You can use the built-in Configuration/Setup Utility program to configure the
parallel connector 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.
Complete the following steps to view or change the parallel-connector assignment:
1. Restart the server and watch the monitor screen.
2. When the message Press F1 for Configuration/Setup appears, press the F1
key.
3. When the Configuration/Setup Utility menu appears, select Devices & I/O
Ports; then, press Enter.
4. Select the parallel connector; then, use the arrow keys to advance through the
settings available.
Note: When you configure the parallel connector as bidirectional, use an IEEE
1284-compliant cable. The cable must not exceed 3 meters (9.8 feet).
5. Press Esc twice to return to the Configuration/Setup main menu; then, select
Save & Exit Setup to exit from the Configuration/Setup Utility main menu.
Parallel connector
There is a 25-pin, female D-shell parallel connector on the rear of the server. See
"I/O connector locations" on page 64 for the location of this connector. The
following table shows the pin-number assignments for the parallel connector.
