What's Mechanically Active Materials Environment Requirements for the Proper Running of the server

Electromagnetic Phenomenon Specifications Low frequency magnetic field Frequency (Hz) 50-20,000 Ampl. A/m (rms) 0.025-10 Amplitude modulation RF electric field Frequency (MHz) 0.009-18,000 Ampl. V/m (rms) < 3 Pulse modulation RF electric field Frequency (GHz) 1-18 Ampl. (V/m (peak)) < 3

Static electricity may damage the chips on integrated circuit boards and cause faults in software and electronic switches. Statistics show that 60 percent of damaged circuit boards are caused by static electricity. Therefore, it is essential to take effective ESD protection measures. The absolute value of electrostatic voltage must be less than 1000 V.

This section describes the requirements for climate, organisms, chemically active materials, and mechanically active materials for the proper running of the server.

Plants and animals are not allowed in the TR. To meet these requirements, take the following measures in the TR: Keep the atmosphere dry. Prevent molds on everything. Block cable holes and antenna holes. Clean and sterilize the TR periodically.

Ground cables must not be bound or entwined with signal cables. If they are parallel, the distance between them cannot be shorter than 3 centimeters. The incoming and outgoing signal cables, power cables, and optical cables to and from an office must not twine around the signal cables and power cables in the TR. If they are parallel, the distance between them cannot be shorter than 5 centimeters. Ground cables must not be led in from above. They must be underground or arranged indoors. PGND cables should be routed straight and as short as possible, and must not spiral. A PGND cable should not be longer than 30 meters, and should be as short as possible. The protection ground bar should be installed at a place less than 30 meters away from the server.
