11 Basic Trouble Shooting
11.1 No input or output signals present
•
Confirm using GUI status LEDs whether the problem is input or output related
•
Check SDI and fibre cabling
•
Check inputs are enabled (off by default)
•
Check outputs are enabled (off by default)
•
Check correct IP protocol has been selected
•
Check IP flow parameters (protocol type, IP address, VLANs, ports etc.) are
configured correctly
•
Check Ethernet Interface IP parameters are configured correctly
•
Check Ethernet Interface link present LED is illuminated on GUI
11.2 Errors in the IP flow’s video content
•
Check the ‘Ignored packets’ count on the Ethernet Interfaces tab of GUI is
incrementing in no more than values of 10s. Incrementing in values of 100s indicates
a network flooding problem.
•
Check the ‘Ignored multicast’ LED on the Ethernet Interfaces tab of GUI is not
illuminated. If illuminated, this indicates multicast packets are being flooded to the
card’s Ethernet Interface port, a likely cause of which is incorrectly configured IGMP
on the network switch.
•
Check input flow network status for lost or duplicate packets. Check maximum gap is
less than 12000ns (0.012us). Larger gaps could indicate bursts in the IP packets.
11.3 IP flows keep stopping after a few minutes
•
Check IGMP is enabled and correctly configured on the network switch.
