this test program verifies configuration of the dfe-550tx as set by the installation procedure, and assists with isolation of any faults in operation. verification and testing procedures are optional, and will only be useful in the unusual event that there is a fault, such as an interrupt number conflict among your computer expansion cards. if your installation provides normal operation, you might choose to skip these procedures.

    the verification/diagnostic program provides two levels of testing: adapter function testing and network operation testing. adapter testing includes a variety of diagnostic procedures.

    adapter testing does not require substitution of a loopback cable. all procedures of the adapter test may be carried out with the network cable connection in place.

    for the network operation test, the cable connecting your station with its supporting hub must be in place.

    network testing involves the broadcast transmission of test packets from the primary station. the test cannot be fully implemented unless a second station on the lan is available to the network operation test, in order to return the test packets to the primary station.

    to run the verification/diagnostic program, proceed with these steps:
