5.7.3 Q-Bus Option Loopback Testing
Module self-tests run when you power up the system. A module self-test can
detect hard or repeatable errors, but usually not intermittent errors.
A pass by a module self-test does not guarantee that the module is good,
because the test usually checks only the controller logic.
Table 5–5 lists loopback connectors for common devices. Refer to the
Microsystems Options manual for a description of specific module self-tests.
