Environmental Conditions

The location should be examined for the following environmental hazards:

!Dust - floating dust must be kept to no more than 0.3 mg/m3. Dust should be held to less than 0.15 mg/m3.

!Radio Frequency (RF) - Normally, there is no need to worry about the effect of radio frequency interference on computer operations. In areas where strong waves are generated or where a high-frequency device is installed on the same floor as the server, radio frequency can affect the functionality of the system.

!Magnetic Fields (MF) - Normally, there is no need to worry about the effect of magnetic fields on computer operations. If the server is installed near cables or transformers that permit the flow of high currents, functionality can be affected.
