Question 1 of 27070

What condition would cause failure of an Inmarsat-C terminal to power up when AC voltage is present at the input terminals of the power supply?

🔍 Key Concepts

• Power supply path inside the Inmarsat-C terminal (AC input, internal conversion, DC output) • Difference between a power-up problem and a signal/communication problem • Which components actually affect whether the unit turns on vs. only affecting receive/transmit quality

💭 Think About

• If AC is present at the input terminals, what must still happen inside the power supply before the terminal can turn on? • Which of these choices would prevent any lights or signs of life on the terminal, and which would only affect the ability to send/receive data? • Which option affects only display/monitoring, and which affects the core electronics getting DC power?

✅ Before You Answer

• Identify which choice deals with internal conversion of AC to DC power for the terminal electronics. • Eliminate any options that only affect RF/IF signal path but do not stop the unit from powering up. • Eliminate any option that is only an external peripheral problem and does not affect the terminal’s internal power state.
