Status Green All diagnostics pass. The module is operational
(normal initialization sequence).
Orange One of the following occurs or occurred:
• The module is booting or running diagnostics
(normal initialization sequence).
• The inlet air temperature of the system has

should immediately correct the environmental
temperature and restore the system to normal
operation.
Red One of the following occurs or occurred:
• The diagnostic test failed. The module is not
operational because a fault occurred during the
initialization sequence.
• The inlet air temperature of the system has
exceeded the safe operating temperature limits of
the card (a major environmental warning). The
