Description
The LED turns s green when all the fans are operational.
The LED turns red when a fan failure is detected.
When the LED is off, it signals that the –48 VDC output voltage is
within the normal operating range. Output voltage between the
minimum and maximum limits will not create an output fail alarm,
and output voltages below the minimum or above the maximum will
create an output fail alarm.
The Led turns red to indicate that the –48 VDC output is out of the
specified range.
When you turn the power supply on, the LED turns red for 2 to 3
seconds to test the LED operation before going off.
