5. What is the recommended location for the Isolation Transformer in relation to the ICT-Equipment location?

The isolation transformer should be as close as possible to the ICT equipment but taking into account potential EM

The isolation transformer should be as far away as possible to the ICT equipment to avoid potential EM

The isolation transformer has to be installed within the power entry point of the building due to electrical code (regulation) requirements.

The isolation transformer should be installed within the rack in which the ICT equipment has been installed.

6. What is a potential risk when using floor mounted cool air ducting systems?

The neighboring racks could have a potential cooling impact.

There are no risks when using floor mounted cool air ducting systems.

Using floor mounted cool air ducting systems will increase the Computer room relative humidity.

Using floor mounted cool air ducting systems will increase the Computer room temperature

7. When having two non-synchronized power sources, the ATS / STS need to be of the type:

Break before make.

Make before break.

Both make before break or break before make can be used.

Both an ATS and STS can never handle two non-synchronized sources.

9. Escape route signage should be placed where?

Only at emergency escape doors

Only at the main entrance of the data centre building

At every door providing a pathway

At every door including riser doors, doors of storage closets etc.

10. What should be a consideration when having casters (rollers/wheels) or feet under the rack?

The casters and feet should be larger to avoid a too heavy point load on the floor tile.

Skirts at the bottom of the rack to avoid air flow between the hot and cold aisles.

Casters and feet should be of a soft material, for example rubber, to avoid damage to the raised floor tile.

Casters and feet should not be locked to ensure the racks are still able to be moved to another position.

16. What is the main difference between an Environmental Monitoring System (EMS) and a Building Management System (BMS)?

An EMS provides local alarms. A BMS provides both local and remote alarms.

A BMS is only able to monitor dry contacts (on/off). An EMS can also monitor analog values.

A BMS only operates as a stand-alone system. An EMS can be configured as a redundant system.

An EMS monitors only. A BMS monitors and controls.

17. What is a disadvantage of a Dynamic UPS?

They are heavy and more noisy.

It needs a separate back-up generator as their autonomy time is less than 60 seconds.

It needs additional cooling infrastructure as high temperatures reduces the lifetime of a Dynamic UP

They are only available for small to medium sized data centres, due to their limited capacity of 200 kVA

18. By what are magnetic fields of the type 'H' or 'B' created?

Magnetic fields are created when an electric current flows; the greater the current, the stronger the magnetic field.

Magnetic fields are created by the magnetic flux of the earth which varies per month.

Magnetic fields are created by voltage; the greater the voltage, the stronger the magnetic field.

Magnetic fields are created when there is a high level of common mode noise (CMN); the greater the common mode noise (CMN), the stronger the magnetic field.

21. Do I need to check the local standards if I already comply to international standards?

Local standards do not to be checked as some countries have too many local standards, which will slow down the data centre construction.

You need to check the local standards to ensure compliance to these standards.

Compliance to only international standards is good enough as most local standards are derived from international standards.

Data centres only need to comply to international standards since they are connected to a worldwide international network infrastructure.
