3-12 Installation

Boot Cycle

After connecting the proper cabling to the DCT6400, plug the power cord into the DCT6400 and

electrical wall outlet. Begin performing the boot cycle procedure:

 After a few moments, the LED displays HUNT and then FR 1.

 The DCT6400 searches for the headend out-of-band (OOB) frequency carrier. If the OOB

frequency is not set to 75.25 MHz, the LED flashes FR 1 and then flashes FR 2. This

searching process repeats until the correct OOB frequency is found and the required

message for the DCT6400 model is acquired.

The LED displays and OOB frequencies are:

Au N/A

Authenticating code object (displays only after download)

 When the correct OOB frequency is acquired, the LED flashes FR number.

 When multiple OOB frequencies are used, the DCT6400 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.
