Appendix C
Front Panel Indicators
This appendix describes the functions of the seven front panel LED indicators on the VXIpc-486
Model 500 Series computer. The significance of each LED is determined by its color: red,
green, or yellow. Red indicates a system failure, while green indicates an active state, and
yellow indicates that a board resource is being accessed.
The red SYSFAIL LED is lit whenever the VMEbus signal SYSFAIL is asserted. The
SYSFAIL LED does not indicate which VXIbus module is asserting the signal. It indicates
only that one of the modules is driving SYSFAIL on the VXIbus backplane.
When the FAILED LED is lit, the VXIpc-486 is driving the SYSFAIL signal. The FAILED
LED and the green TEST and ON LINE LEDs indicate the status of the VXIpc-486. The status
LED indications are shown in Table C-1. A successful system startup will sequence through the
first six states. The point of failure is indicated for states where the FAILED LED is lit for an
extended period of time.
