How shall data processing systems be disconnected?

Data processing systems must be disconnected by approved means to ensure safety, reliability, and compliance with applicable regulations. Approved means refer to methods and procedures that have been recognized and validated through industry standards or local codes, particularly those outlined by the National Electrical Code (NEC) or other governing bodies.

Using approved means ensures that the disconnection process effectively prevents potential hazards, such as electric shock or data loss. It may involve specific procedures for safely shutting down various components or systems, ensuring that equipment is disconnected without damage or risk to personnel. This methodical approach is crucial in environments where sensitive data is processed and where equipment integrity is paramount.

In comparison, using any means, manual shutdown, or simply cutting power may not provide adequate safety or adherence to technical standards. These alternatives could potentially jeopardize both the operator's safety and the system's integrity, leading to unintended consequences. Therefore, disconnection according to approved means is the best practice in maintaining a secure and effective operational environment for data processing systems.
