intermediate line amplifiers) has DC power and trace the connection from the LNB to the IRD or try replacing the LNB. If a spectrum analyzer is available, look for the carrier at the L-band intermediate frequency. (For domestic C- band satellites, this is 5150 minus the downlink frequency in MHz.)

b.The selected IRD RF port has failed. To rule out this possibility, try connecting the RF cable to another RF port and select that port (or use the RF Switch Bypass to force that other port).

c.The IRD receiver card has failed. To rule this out, try using another IRD.

2.If the first alarm message is “No Carrier Lock”, verify the RF Feed Port, Carrier Frequency, Data Rate, FEC Ratio, and ID Tag (if Tags are in use) settings. Also verify that the LNB LO frequency setting (in the IRD) is correct for the selected RF feed port.

3.If the alarm message is “RF Signal Overload”, then reduce the carrier power entering the U4600. Either add in-line attenuation (a splitter will do) or remove line amplification in the RF circuit between the LNB and the IRD.

The U4600 may not be authorized for the network’s Conditional Access. If the AUTH LED is Off and the alarm message, "Unauthorized for CA” appears, contact your net- work provider to gain authorization in its Conditional Access database.

Alarm or Warning LED On

Check the front-panel display for alarm or warning messages. Table 4.1: Alarm and Warning Descriptions on page 49 describes U4600 alarm and warning messages. If the message definitions are too technical to help debug the problem, report the mes- sages to your network provider.

If no alarms or warnings are shown, suspect a bad connection or mis-programming of the U4600:

1.If audio or video are missing, check the front-panel monitor jacks. If the front mon- itor connections are OK, check the signal connections from the rear of the unit to the destination. If an audio is missing from the rear-panel outputs and cannot be detected at the front-panel monitors, check that a valid audio stream is selected for that port and that the network provider has supplied non-quiet programming on that audio.

2.If the ASI output is missing, check the signal connections from the rear of the unit to the destination. If okay, check with the network provider to verify what Program Mapping (Release 2 or later) may be in effect.
