Non-Computing Power Supply
The non-computing power supply (air-conditioners, lighting, etc.) must be separated from the
data processing power supply by specific distribution units. Specific current outlets must be
installed in the Computer Room to this effect.
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.
3.6.1.
Ambient Lighting
Lighting must be separated from the data processing power supply by a specific distribution
unit. 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.
3.6.2.
Emergency Lighting
Autonomous emergency lighting units must be installed. If lighting in the Computer Room is
accidentally turned off, self power-supplied lighting boxes must indicate the Emergency EXIT
(
green marking mandatory), for the safe evacuation of personnel.
