EMU Status
Operational Enclosure
The subsystem is fully operational.
The power supplies and blowers are
functioning properly. The EMU intake and
backplane exhaust air temperatures are within
user-specified limits.
Overtemperature Condition
Probable Cause 1—A temperature in one or
more enclosures is above the user-specified
limit.
Determine and correct the cause of this
condition quickly to prevent an
overtemperature condition from inducing a
subsystem RESET or failure.
Probable Cause 2—A temperature set point is
too low for this environment.
Change the temperature set point.
Nonoperational Enclosure
Probable Cause 1—Either + 5 V dc or 12 V dc
out of range.
Observe the individual power supply status
LEDs to determine the defective power supply
and replace it.
Probable Cause 2—TERMPOWER less than
+ 4.5 V dc on one or more I/O modules.
Replace the I/O modules displaying a
TERMPOWER LED OFF indication.
