HostDARTFault
Major Summary status of
DART upconverter
and/or
downconverter and
DART FPGA status.
The clock source for
the DART is outside
an acceptable range
or the DART FPGA is
not programmed.
may also occur with
the
DARTDCSupplyFault.
Inspect
Active
Alarm List
for
upconverter and/or
downconverter
alarms. If these
alarms are found
and persist, consult
ADC, replace DART.
If no
upconverter/downc
onverter alarms are
found, unplug DART
from Host, then
replug DART in Host
to reload the FPGA. If
persistent, consult
ADC, replace DART.
HostDARTHardwareMismatchFault
Major Indicates a hardware
mismatch for the
DART boards
between linked Host
and Remote
Check if a linked
DART of one type
was unplugged and
not decommissioned
then replaced with a
DART of another
type. Make sure
linked Host and
Remote DARTs are
of same type
HostDARTOverDriveFault
Major the RF signal
received from BTS is
greater than +5dBm.
The allowed range is
-25 dBm to +5 dBm.
Lower the gain on
the Host DART. If
persistent when
gain is zero, lower
power of BTS RF
signal. Maximum
power at zero gain is
+19dBm.
HostDARTUnderDriveFault
Minor When the Host input
level is 20 dB less
than the expected
Host DART Input. For
example, for 30 dB of
Host DART gain (-25
dBm expected input),
the threshold is -45
dBm. For 0 dB of
Host DART gain (+5
dBm expected input),
the threshold is -15
dBm.
Increase the gain of
the Host DART. If
persistent when
gain is at maximum,
increase power of
BTS RF signal.
HostDARTUpConSynLockFault
Major Lock state of the
upconvertor
synthesizer
If persistent, consult
ADC, replace DART
