DCT5100 Installation Manual
When multiple OOB frequencies are used, the DCT5100 pauses 40 seconds on each valid
frequency. The LED displays
dl
and a progress indicator, which identifies a software object
download. The progress indicator, or crawling ant, moves one position around the dl display
for each segment of download received. If the
dl
stops moving up and down on the LED for
an extended period of time, contact the headend operator.
The progress indicator usually moves at a consistent rate as segment downloads are
received. If all the segments are retrieved in the first pass, the
EF
,
AU
and
FP
messages are
displayed on the LED. If segments are dropped, the progress indicator appears to stall and
then inch forward after the dropped segments are retired.
When the progress indicator alternates between rapid and sluggish movement, this may
indicate that the stream is spinning too fast for existing plant conditions.
The LED displays
EF
for up to 60 seconds when the software object download is complete
during flash erasure and then displays
FP
for up to 60 seconds during flash programming.
The DCT5100 is ready for initialization by the headend controller when the LED display is
blank. Verify that the DCT5100 is powered up or reset within two minutes of a completed
download.
Boot Cycle Error Codes
If hardware or software problems occur, the DCT5100 displays error codes on the LED display.
