Option 01 VXI Interface Module User Manual
1–11
During a commanded self test:
1. SYSFAIL* is not asserted.
2. The module executes the same instrument self test as is executed upon power
on.
3. When the self test is completed,
the modules controlled by the Option 01 are
restored to their pre-test state.
SYSFAIL* becomes active during power-on, hard or soft reset, or self test, or if
the module loses 5 V power. When the mainframe Resource Manager detects
SYSFAIL* set, it will attempt to inhibit the line. This causes the Option 01 VXI
Interface Module to deactivate SYSFAIL* except when +5 V power is lost on
the relay module on which it is installed.
