Final answer:
Additional power supplies provided for equipment essential to system operation located away from the main control serve as backups to ensure an uninterrupted power supply. They are commonly used in data centers and hospitals.
Step-by-step explanation:
Additional power supplies provided for equipment essential to system operation located away from the main control shall be used to ensure uninterrupted power supply to the equipment. These power supplies act as backups in case of a power outage or failure of the main power supply. They are commonly used in data centers, hospitals, and other critical infrastructure facilities to ensure the continuous operation of essential equipment.
For example, in a data center, servers and networking equipment are essential for system operation. Additional power supplies, such as Uninterruptible Power Supplies (UPS), are installed to provide backup power in case of a power failure. This ensures that the servers and networking equipment remain operational and data integrity is maintained.
Similarly, in a hospital, medical equipment like life support machines and monitors are essential for the system to operate effectively. Additional power supplies, such as generators, are installed to provide backup power in case of a power outage. This ensures that critical medical equipment continues to function without any disruptions.
