What is one of the steps involved in applying power to the ITUs within the DMR?

Applying power to the ITUs (Integrated Terminal Units) within the DMR (Digital Modular Radio) system involves powering up the SDCs (Signal Distribution Cards). This step is crucial because the SDCs manage signal routing and distribution to the ITUs, ensuring that each unit receives the appropriate power and connections necessary for operation.

By powering up the SDCs first, technicians can verify that the entire system is functioning correctly and is capable of handling the signals from the ITUs as intended. This is a foundational step before proceeding with further configurations or checks, as without proper power to the SDCs, the ITUs would not be able to operate effectively.
