Table 14. Alarm condition description.
The description of the severity levels of the different alarms are given in
Section 5.2.6.
Alarm Description Error source
Bitrate regulation in
progress The regulation algorithm is working with
bitrate estimation. This alarm may stay on the first minutes
after tuning to a new IP stream. If the
alarm does not clear, the input stream
may be a variable bitrate stream.
SNTP server
unreachable Unit is unable to connect to SNTP
server. There is no SNTP server on the
configured IP address or there is no
contact with the SNTP server due to
network problems.
No sync No valid ASI input stream detected. The problem can be related to a
problem with the sending device or the
cable.
Too high
temperature Internal temperature of unit is too high. The fans are not working or forced
cooling is required.
Sequence error Analysis of the sequence number of the
RTP layer indicates that IP frames have
been lost or that they have been
received out of order Typically this error is generated by
packets being dropped by some
equipment in the network, f.ex when a
link is overloaded.
Defective fan There is an error with fan of the unit Hardware problem.
No data received No data received on Ethernet input for
stream The most likely error is that there is a
set-up problem where IP address and
UDP port are not correctly configured.
The error can result from an error with
the transmitting unit or an error on the
network.
No lock The IP receive channel is not able to
find an initial bitrate for the data
received. The stream contains a PCR PID with an
invalid clock reference.
Data lost Stream received is incomplete and a
valid ASI output can not be expected See ‘Sequence errors’. If you have
‘Sequence errors’ but not ‘Data lost’, all
frames are received but they are out of
sequence, or enough data is received
for the FEC engine to correct all lost
frames.
ARP unresolved IP address not resolved into physical
MAC address. This error may be caused by wrong
default gateway configured, wrong
unicast IP address on same subnet or
unit on same subnet does not respond.
Ethernet link down No link on Ethernet layer No connection on physical layer.
Input buffer
overflow The total bitrate of the IP input streams
is too high. There is a configuration error or one of
the sources is generating a too high
bitrate.
Output buffer
overflow The total bitrate of the ASI input
streams is too high. There is a configuration error or one of
the sources is generating a too high
bitrate.
