Fitting out the Premises
Electrical / Electromagnetic Interference
Generators of electromagnetic interference may adversely affect server operation. The
following sources of electrical and / or electromagnetic interference must not be located in
the immediate vicinity of the Data Processing Center:
• high-voltage lines,
• radars,
• radios or other transmitters.
The server must not be subjected to electric / magnetic fields in excess of:
• electric field (E): 3 V/m,
• magnetic field (H): 30 A/m.
Warning:
The installation of an "on-line" Uninterruptible Power Supply (UPS) is strongly recommended
to ensure continuity of service and to protect the system in the event of a mains failure.
The UPS may be installed in the Computer Room or in an ancillary room.
Fire Protection
For effective fire protection, the fire detection and extinction system must be specially
designed for the Data Processing Center, which must be located in a fire area surrounded by
fire-protection walls, partitions and doors.
Fire Detection
The Customer must ensure that the following areas are monitored:
• the raised floor plenum,
• the Computer Room environment,
• the suspended ceiling plenum (where applicable),
• adjacent and ancillary rooms.
Ionic, optic, thermovelokinetic type detectors are generally used for fire detection.
The detection circuit must comprise at least two independent loops, each of which must be
equipped with different detectors.
Extinguishing Procedure
The extinguishing procedure must delay the emission of the extinguishing agent in order to:
• warn (visual and audio signals) and evacuate personnel,
• give a visual alarm outside the premises as to the presence of extinguishing gases,
• cut off power (hardware, lighting, air conditioning) - except emergency lighting units.
It is recommended to install portable extinguishers in the Computer Room and ancillary
rooms ("water sprays" in the vicinity of paper systems and storage) for use in the event of
small, contained fires.
Note:
If the server is installed in a room equipped with water sprinklers, water pipes must only be
loaded subsequent to a primary detection.
