CHALLENGE/Onyx Diagnostic Road Map 3-17
Table 3-4 provides the voltage ranges monitored by the System Controller, and two sets of
voltage thresholds: the upper and lower thresholds at which a voltage warning is issued,
and the upper and lower thresholds at which the system is shut down.
Note: The POK signals are asserted at the undervoltage limits. If a specific test circuit fails
to assert POK, the System Controller initiates a system shutdown.
a. Below this voltage the system shuts down.
b. Below this voltage a warning is issued.
c. Above this voltage a warning is issued.
d. Above this voltage the system shutdown.
