HostSERFSynthAlarmFault
Major The configured clock
source is not
providing an
acceptable signal
If clock source is
onboard and
persists, consult
ADC, replace system
card. If clock source
is external, check
clock source,
connection
HostSysCardFanFault
Major The Host fan is
spinning too slowly
Check fan for
mechanical problem.
If not fixable,
consult ADC, replace
fan
HostUnderTempFault
Minor The temperature of
the Host is under its
lower operating limit
(-40 degrees
Fahrenheit )
Check ambient
conditions
RmtAcPowerSupplyFault
,
RmtACPowerSupplyMon1Fault
Major A power supply is in
a failed state
If persistent, consult
ADC, may have to
replace one or more
power supply
located in the SeRF
Module
RmtDARTDCSupplyFault
Major The on-board DC
voltages are out of
their valid ranges
If persistent (may be
transient on
startup), check If the
DC power switch to
the DART is in the
OFF position. If DC
power is ON, reset
set the RF Module. If
the alarm persists,
consult ADC, as you
may have to replace
RF Module

Major Lock state of the
first downconverter
synthesizer
If persistent, consult
ADC, replace RF
Module
RmtDARTDwnCon2SynLockFault
Major Lock state of the
second
downconverter
synthesizer
If persistent, consult
ADC, replace RF
Module
RmtDARTFault
Major Summary fault
