Table 2 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 PSU cables and output voltage of PSU.
Replace a cable.
Power Supply failure
Check PSU cables.
Verify if output DC Voltage is in nominal range.
Replace PSU module
Router Failure
Check PSU cables.
Contact your nearest dealer or service center for
advanced support.
ERROR indicator lights

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 (LOCK
indicator is not
lighting constantly)
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.
