POWER LED Indicators Displayed on DHCTs

Some DHCTs do not include front-panel alphanumeric LED indicators. These
DHCTs rely on the flashing POWER LED indicators to give you information about
their status.
Understanding the POWER LED Indicators
Blinks Once Every Half-Second
The POWER LED indicator blinks once every half-second. This is equivalent to the
h.nnn message LED code that appears on the front panel of alphanumeric LED
DHCTs.
An h.nnn condition indicates normal behavior for the DHCT. The condition occurs
while the DHCT scans the entire frequency spectrum for the presence of a CVT. The
DHCT is scanning the QAM frequency spectrum for all of your QAMs.
Blinks 2 Times, Pauses, Repeats
The POWER LED indicator blinks twice, pauses, then repeats. This is equivalent to
the r.xxx LED code that appears on the front panel of alphanumeric LED DHCTs.
An r.xxx condition indicates that the DHCT may be downloading software. Do not
reboot the DHCT. As a CVT download progresses, the hex number decreases
sequentially to zero, showing the number of blocks remaining. Block size is
configured on the headend.
The r.xxx message is normal behavior for the DHCT. Do not reboot the set-top
unless the message appears constantly.
To clear the r.xxx message, complete the following steps.
1 Wait 5 to 20 minutes. The DHCT could be downloading software.
2 Did this clear the message?

If yes, you have corrected the problem.

If no, follow your company's escalation procedure.
Blinks On for Two Seconds, Off Momentarily, Repeats
The POWER LED indicator blinks on for two seconds, off for two seconds, and
repeats. This is equivalent to the BR.xx message LED code that appears on the front
panel of alphanumeric LED DHCTs.
A BR.xx (where xx is a hexadecimal number) message usually indicates that the
DHCT has a software or hardware malfunction that prevented it from properly
receiving an instruction to complete a function. This condition is also referred to as
an OS trap.
