must run the test from a workstation that is not attached to the I/O adapter you are testing. To run this test, you must have more than one workstation I/O adapter on the system.

If this test completes successfully, the workstation I/O adapter card and the cable that attaches to the workstation I/O adapter card are operating correctly.

If this test fails, a display indicates the probable failure rates of the workstation I/O adapter card and the cable that attaches to the workstation I/O adapter card.

Wireless LAN adapter card indicators

The wireless local area network (LAN) adapter has two indicators located above the 8-pin RS-485 connector.

The top-most indicator shows the adapter card status. The indicator closest to the RS-485 connector shows data transmission or reception.

Use Figure 84 to assist in problem analysis.

Communications interface trace

The purpose of this test is to monitor the modem interface signals and to detect wrong or incompatible use of the modem interface.

Starting the trace before varying on the communications lines provides the most accurate sample of the lines that are coming up.

Test description

This test monitors the following five modem interface signals:

vData Terminal Ready (DTR)

vData Set Ready (DSR)

vRequest To Send (RTS)

vReady For Sending (CTS)

vCarrier Detect (CD)
