power-on, when the LANIC TEST (RESET) switch on the LANIC card is
pressed. or when invoked
by

circuitry on the LANIC card as well as performing a simple test of the MAU.
The ThinLAN 3000/V link diagnostic must be run to perform a complete test of
the LANIC card. See the LAN/ 3000 Diagnostic and Troubleshooting Guide. part
number 30242-90003 for a description of the diagnostic.
