12 Researching the requirements
Vibration in the office environment should be limited to a frequency range
of 0.5200 Hz and a G-force magnitude of 0.1 G (according to the Bellcore
Network Equipment Building Systems Generic Equipment Requirements
specification TR-EOP-000063).
Electromagnetic Interference (EMI) -
Sources of EM1 located close to the equipment may have an effect on
system operation. Common EM1 sources known to disturb system
operation are:
- thunderstorms, static electricity, high-voltage power lines
-
radar, broadcast stations, mobile communications
-
power tools, appliances (vacuum cleaners ), and office business
machines (copiers)
-
industrial machines and ultrasonic cleaners
-
vehicle ignition, arc welders, and dielectric heaters
- dimmer switches
Note: The SL- 1 system meets the United States Federal
Communications Commission (FCC) Rules, Part 15, Subpart J and
Canadian Standards Association (CSA) C108.8 for radio frequency
interference and/or electromagnetic interference (RFI/EMI) radiation.
Dust
Average dust density for an office environment must be Zone 4
(0.00014g/m3) or better. False ceilings and tiled floors help maintain dust
density requirements. Accumulation of dust and dirt can:
-
scratch gold contacts on printed circuit packs, causing intermittent
failures
- have conductive contents, increasing component susceptibility to
damage by static electricity
-
cause components to operate at higher temperatures
- be detrimental to system reliability and performance and increase
maintenance and warranty costs
