Description and Tips
Severity
High Temperature
May be caused by unit or remote fan
failures.
Check the ambient temperature to
ensure it is not above the rated
temperature.
Ensure that airflow from the bottom of
the heat sink and above the fans is not
obstructed.
Ensure unit is positioned correctly.
MAJOR
Input DC Voltage Marginal
Unit input voltage is close to exceeding
acceptable range.
Check the reported input voltage.
Adjust input voltage or repair power
feed as necessary.
MINOR
Input DC Voltage Out of Range
Unit input voltage has exceeded
acceptable range.
Check the reported input voltage.
Adjust input voltage or repair power
feed as necessary.
MAJOR
Input Path ALC Active
Input path power has exceeded
recommended levels on the RF port.
Consequently, the ALC has been
activated and the gain reduced.
When occurring on air interface consider
repositioning antenna or increasing
minimum distance between mobile and
antenna.
When occurring on conducted interface
reduce power of feed. The DL output
power from the PA has exceeded
recommended levels. Consequently, the
ALC has been activated and the gain
reduced. Either the input power is also
high, there has been a transient high
input power, or the system gain is higher
than expected.
MAJOR
Input Path ALC Range Exceeded
Input path power has exceeded safe
levels and consequently the RF path has
been deactivated.
Adjust input power setting or add
external attenuation if input power is
above the rated level.
Once the cause has been addressed,
reactivate the RF path.
