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.
Configuration Fault Code Reporting
The system fault, temperature, power, and blower LEDs cannot
display all possible system faults. Therefore, if the system fault LED
is F
, associate this indication with a system fault somewhere
LASHING
within the enclosure. To identify a system fault, observe the blower
LEDs. They represent a hexadecimal code that is presented using the
a binary format. The upper LEDs (8 through 5) display the first digit
(the most significant digit) of the hexadecimal code; the lower LEDs
(4 through 1) display the second digit (the least significant digit) of
the hexadecimal code.
Fault codes are not displayed by the blower LEDs until the
user momentarily presses the F
switch.
