Non-Computing Power Supply
Prerequisites
• Installation of current outlets around the edge of the computing room.
• The non-computing power supply (air-conditioners, lighting, etc.) must be separated from
the data processing power supply by specific distribution cabinets.
Note:
The Customer is responsible for supplying the complete electrical installation, from the power
delivery station through to the cable outlets at the base of the server cabinet. The electrical
installation must comply with the standards in force.
Ambient Lighting
Lighting must be separated from the data processing power supply by a specific distribution
cabinet. The position of lights must ensure homogeneous lighting. It is preferable to
flush-mount lights in the suspended ceiling. Average lighting measured at 0.85 m from the
ground must be 500 Lux (ISO 8995, future EN 12464-1).
Lighting options are:
• Instant-lighting tubes equipped with interference suppressors to limit electromagnetic wave
interference.
• Halogen lamps without intensity regulators.
Emergency Lighting
Autonomous emergency lighting units must be installed. If lighting in the Computer Room is
accidentally turned off, the emergency lighting system must indicate the Emergency EXIT
(green marking mandatory), for the safe evacuation of personnel.
