35.4 Troubleshooting Common Problems
The most common problems encountered with the COM3000 systems are due to poor RF signal
conditions or to bad or loose connections.
Before moving on to detailed troubleshooting of any problem, you should check the following:
➢
All necessary connections (Power, Ethernet, and coaxial cables) are fully plugged or screwed in.
➢
Proper RF signal levels are available at the inputs to the system.
➢
A AT&T / DIRECTV AIM meter must be used to test signal quality. An EIV test must return a fully
passing result on all transponders.
➢
COM51 RF input 1 is the lower RF input, connection of a DSWIM to this input will facilitate use
of the first 16 tuners.
o
A DSiM connection to input two is required for a COM51 with 17 or more active tuners.
➢
Once you have ensured that all RF parameters are correct, try retuning and/or rebooting any
problematic cards.
If the problem persists, look over the following tips and review the appendices before contacting
your distributor.
35.5 Features and Licensing
The COM51 must be licensed to stream signal. In systems with a QAM20 or NTSC-8 this
license will be provided via the hardware when connected to the COM400 chassis.
If you are using a COM51 system in an IPTV system with no QAM or NTSC-8 the cards will
need to be licensed for use by your distributor.
➢
Symptoms of no IP license:
o
All tuners will work after re-boot, after several minutes all tuner >1 will stop. COM51
card will display tuner >1 in red.
o
Syslog will report, “No QAM found need license”.
Loading a COM51 license file overwrites any existing license in the card. Any new license file
must contain any existing licenses.
Tuner licenses are a separate file and will not affect or be affected by feature license files.
Technicolor support cannot load feature or tuner licenses on your equipment. You must contact
your distributor.
