System is VAX or VAX, but
feature key is not correct
All status LEDs red. System is VAX or
VAX, and feature key
is correct
Micron Front Panel
detected, but VAX or
VAX is not enabled
in feature key.
SYSTEM FP FPGA
programming error
System is VAX, but front
panel is not programmed
All LEDs orange. Front panel is
programmed
