LED Indications after Power-Up
Within approximately 15 seconds of power up, the IRD gives an indication of stable operation. It
initializes all system components and supplies an operational status. A steady Green LED indicates
that it is locked on a carrier and is capable of producing output (Audio/Video/Data).
If there is some problem with the IRD or the signal it is receiving the LED flashes Red for alarm
conditions or Amber for warning conditions. In general, alarms indicate that the unit cannot produce
output, while Warnings indicate that, although output is being produced, there is a problem that could
require attention. The most common conditions that produce alarms or warnings are listed in
Table 3.
