After turning on the UPS, what is the next step in powering on the TSC?

The correct next step after turning on the UPS (Uninterruptible Power Supply) is to turn on the Rectifier. The Rectifier is responsible for converting AC power to DC power, which is essential for the proper functioning of the Tactical Session Controller (TSC). Once the UPS is operational, ensuring that the Rectifier is powered on allows the system to receive stable power, enabling all subsequent components and systems to operate effectively.

Turning on the Rectifier after the UPS ensures that the TSC and other connected devices receive the correct type of power required for their operations. This sequence is critical because the Rectifier provides the necessary power to the system, without which the TSC would not have the energy needed to start up and function.

Performing a system self-test, while important, is generally done after the necessary power sources are operational to ensure that the system can accurately test its components and functionality. Powering on the LSC (Local Session Controller) and turning on the Ethernet Switch are also steps that follow the initialization of power systems, making them secondary actions in the sequence. Hence, ensuring that the Rectifier is powered on is crucial to successfully powering on the TSC.
