Non-conductive airborne particles can be minimized by: Doing all unpacking, cutting, and drilling outside the computer room Keeping cardboard boxes and manuals outside the computer room Prohibiting food or drink inside the computer room Avoiding carpets ...

Underfloor concrete shall be cleaned and sealed after all major underfloor work has been done, including installation of the access floor system itself. The access floor shall be a minimum of 450 mm (18 in) above the slab. When determining the minimum raised ...

In data center computer rooms and telecommunications spaces (e.g., entrance rooms, TRs), the minimum ceiling height should not be less than 3 m (10 ft) from the finished floor to any obstruction such as sprinklers, lighting fixtures, or cameras Minimum 450 mm...

Equipment cabinets and racks shall be braced in accordance with local codes. Cabinets braced at the top can utilize the cable ladder rack system, if present, with an attachment that provides rigid four-directional lateral bracing. Equipment mounted on access f...

Local building codes shall be consulted in the planning and implementation of changes to the building and its mechanical, electrical, and life safety systems. All loads on the structure are divided into various types: Dead loads, soil loads, hydrostatic press...

Floor loading (superimposed live load) shall be a minimum of 7.2 kPa2 (150 lbf/ft2) with 1.2 kPa (25 lbf/ft2) hanging dead load (weight that can be supported from the underside of the floor or roof). This floor load is adequate for most data center areas. 1.2...

Electrical distribution systems for data centers are designed to power the center safely and reliably and this section will also address the power distribution and monitoring solutions that have been successful in meeting these demands, and how data centers ca...

Transformers usually transform the utility’s medium distribution voltage to a lower voltage for utilizationby the data center. The substation might transform voltage in excess of the site requirement and an on-site utility transformer might then transform the...

Backup generators should be there as a backup to data center equipment in case of utility power failure. Emergency generators should be there to power the data center life safety systems (e.g., emergency lighting, fire pumps) if utility power fails. The datac...

All electrical equipment must have redundancy to increase both fault tolerance and it must be documented well to maintain to avoid the outage due to human error, and this helps to maintain the overall redundancy in data centers. The capacity is kW required to...

The standard includes five Classes relating to various levels of reliability of the data center  facility infrastructure. The Classes are completely performance related, and it is mandatory to implement Class F3 and F4. The five Classes are: Class F0 - a si...

UPS and critical power system applications are focused on delivering quality power, whether originating from an electric utility or from internal energy storage, on an assured, 24/7 basis. Datacenter should have reliable device to maintain the business contin...

Synchronization can occur in one of two ways for UPS systems: Actively based on some form of external control system Passively by the management of the static switch inputs to the given modules or via active systems specific to the UPS manufacturer, depend...

Output switchboards directly support the PDU and ASTS systems downstream of the UPS power plants. For Class F1, F2, and F3 systems, UPS outputs should be vertically organized to the UPS output distribution system downstream. Simpler electrical topologies may n...

If the UPS sources are synchronized and are not overloaded, UPS systems may transfer load between each other. Except on a plant level, the UPS is the foundation of the multi corded system for critical loads. All transfers are done via closed-transition, and t...

UPS output distribution switchboards are located immediately downstream of the UPS power plants and extend to the PDU or data processing room levels. One important consideration for these systems is that they do not have to follow the redundancy level or plan...

PDUs with an isolation transformer create a separately derived neutral for downstream loads although this may not be necessary for 3-phase loads or for systems in which the load utilization voltage is created at the UPS. PDUs with transformers convert the out...

DC power systems that serve critical loads are common in two forms: The primary power source for access provider and carrier equipment. As an alternative to AC power in computer rooms because of energy efficiency, design simplification and ease of parallel...

The distribution to the critical loads must be exactly mapped to the redundancy of those loads and the cord and circuit diversity that they require. The upstream systems must be able to deliver the source diversity to the computer room circuiting under normal...

Unused or abandoned cables not terminated at equipment or marked for future use shall be removed. Load connection best practices for facilities are listed below: Twist-lock receptacles and plugs for all underfloor or overhead receptacles should be provided....
