Subsystem Status
The subsystem is fully operational.
Comment
The dc power supplies and the blowers are operating
properly. The ambient and exhaust air temperatures
are within the user specified limits.
Over-temperature condition. Overheating can cause
system failure.
Probable Cause
The ambient temperature in one or more enclosure is
above the user-specified limit.
Temperature set point may be set too low for
environment.
Corrective Action
Complete first corrective action. If it does not correct
the problem, complete the second.
Determine and correct the cause of this condition as
quickly as possible to prevent the over-condition from
causing a subsystem reset or failure.
Change temperature set point.
Non-operational
Probable Cause
One of the following error conditions exists:
5 V dc or 12 V dc out of range.
TERMPOWER less than + 4.5 V dc on one or more
I/O modules.
Corrective Action
Complete first corrective action. If it does not correct
the problem, complete the second.
Observe the power supply status LEDs to determine
the defective power supply and replace it.
Examine I/O modules to find the one with either the
external or internal TERMPOWER LED ON and
replace it.
