Certified Data Centre Professional (CDCP) Practice Exam

Installing a small single-phase 10KVA Uninterruptible Power Supply (UPS) inside the computer room is typically not acceptable due to various factors that can impact the overall performance and safety of the data center environment.

Firstly, noise generated by the UPS can disrupt sensitive equipment. UPS units can produce significant operational noise, which can be detrimental to server performance and maintenance activities in a quiet data center setting. In addition, the heat produced by a UPS can contribute to elevated temperatures in the computer room, potentially compromising the cooling capabilities for critical systems.

Moreover, having UPS units located within the same space as the servers raises concerns about electromagnetic interference (EMI). The UPS could emit electromagnetic fields that interfere with the sensitive electronics present in adjacent equipment. While some might consider physical distance to mitigate this, it is generally better practice to install such equipment in dedicated electrical rooms designed to handle these concerns.

Lastly, there are specific codes and standards related to power equipment installations that may require certain clearances and separation from data processing equipment to ensure safety and compliance. This ensures the reliability and stability of power supplies to sensitive equipment.

Considering these factors, placing the UPS inside the computer room is not advisable, leading to the conclusion that it is not an acceptable practice.
