4. TROUBLESHOOTING
Table 3 Troubleshooting guide
Symptoms Possible reasons Actions
Router doesn’t work DC power beyond the limits of allowed
values Check DC power voltage
Power cord is broken Check the power cable and output voltage.
Replace a cable.
Router restarts every
3-5 seconds. Short-circuit in transmit cable Disconnect and check Tx cable
Software failure Reset software to factory defaults
No reception from
the satellite (indicator
LOCK is off, single
flashes of ERROR
indicator) Incorrect configuration Check Rx frequency and symbol rate.
IF cable failure Check Rx cable and make sure that its connectors
are properly connected to the LNB and the router.
LNB is not powered Check if LNB power is switched on
Disconnect Rx IF cable from LNB and make sure that
12-18 VDC is available on the connector.
Check Rx level in the statistic of the demodulator.
No carrier on the satellite or its level is
insufficient. Verify availability of the carrier and its level with
spectrum analyzer.
Contact Hub administrator and investigate if the
carrier is properly transmitting and local weather
conditions not attenuate the signal.
Low Rx carrier level Measure carrier signal to noise level with a
spectrum analyzer.
Verify if antenna is properly pointed to the satellite
and there no obstacles in the direction to the
satellite.
Check the integrity of the film of antenna’s feed
horn and absence of moisture in it.
LNB failure Replace LNB to the spare one
High rate of errors of
Rx path Bad weather conditions The quality of reception may temporary decrease
during intensive rainfall, for, thunderstorm
cloudiness.
Check if there is no snow or ice on the antenna
surface and on the feed horn.
Low signal to noise level Check C/N in demodulator’s statistics.
Verify if antenna is properly pointed to the satellite
and there no obstacles in the direction to the
satellite.
Check the integrity of the film of antenna’s feed
horn and absence of moisture in it.
Low Rx carrier level
Interferences Check Eb/No in demodulator’s statistics.
Contact Hub administrator and investigate if the
carrier is properly transmitting and local weather
conditions not attenuate the signal
Station is not
transmitting Wrong network setting Check Tx frequency and symbol rate of the
modulator. Make sure that transmission is enabled
