For example, when the LANCE 802.3 port test starts, the following appears on the screen:

lance_1(

When the routine is completed successfully, a right parentheses appears, followed by the next routine. For example, when the LANCE routine is completed and the LANCEMEDIA routine begins, the screen display is as follows:

lance_1 (0123)

lancemedia_1(

When the entire self-test routine is completed, the Bridge Module identification header is displayed.

When an error occurs, additional information may appear on the screen depending on the routine running at the time. Be sure you record this information before calling Customer Support, as described below.
