Green - the mainframe is turned on.
Amber - the mainframe is in standby mode; no power is applied to VXI modules.
Both Indicators Off - there is no power applied to the mainframe.
Green - all voltages, currents, and power supply temperatures are within expected
operating ranges.
Flashing Amber - one or more power supply measurements are out of limit.
Green - all the individual slot temperatures and ambient temperatures are within normal
operating ranges.
Flashing Amber - one or more slot temperatures or the ambient temperature has
exceeded specified limits.
Full - the power supply and mainframe cooling fans are operating at full speed.
Var(iable) - the power supply and mainframe cooling fans are providing user-specified
cooling level. Fan speed is a function of the power supply temperature, ambient
temperature, and individual slot temperatures. Fan speeds operate at the lowest possible
speed to maintain user-specified cooling level.
Green - the power supply and mainframe cooling fans are operating within expected
ranges.
Flashing Amber - the power supply fan or the mainframe cooling fan is not operating
within expected ranges.
Green - there is communication between instruments across the backplane. Off - there is
no communication between instruments on the backplane.
Amber - one or more instruments has asserted its SYSFAIL line due to a power-on
initialization failure, self-test failure, or hardware failure. SYSFAIL is asserted momentarily
at power on and during a system reset.
Pressing the reset button asserts the SYSRESET* line on the VXI backplane. When low,
this line resets the VXI system; all VXI instruments are rest to their power-on state.
