SELF-TEST

This chapter describes how the tests supported by the DEFINITY
High Speed Link are used to isolate data communications
problems. The tests can be controlled by the front panel interface,
the terminal, the remote endpoint, a Digital Data System test
center, or the switch.
Self-test has priority over all other tests. It can be activated from
the front panel at any time, and is activated automatically when
AC power is applied.
The self-test is a disruptive test that
resets the HSL
checks and initializes its internal circuits
displays the results on the LCD during the start-up sequence.

Self-Test
This test should be the first test conducted when any problem is
encountered. Passing this test indicates that the internal circuits
are working properly. The self-test does not check the data
interface to the local DTE or the line interface to the switch. These
interfaces are tested by the other tests.
