The system is designed for use in a relatively clean (office or lab)
environment. To assure reliable operation in an industrial
environment, you may need to provide protection against airborne
particles and other contaminants, especially for the disk or tape
drives and their associated media.
The internal fans provide airflow sufficient for most installations,
but some high-density, high-power VMEmodules may require
additional cooling. When integrating VMEmodules that are known
to run hot, testing is advisable to confirm that these modules are
properly cooled.
Note also that for tape storage media, a maximum safe temperature
of 50° C (122° F) is specified. Since the operating temperatures
within the chassis will always be greater than the air inlet
temperature, avoid using tapes if the inlet temperature exceeds 40°
C (104° F).
No forced-air cooling is provided for the rear-mounted modules.
The rear-mounted modules are typically transition boards with few
active components, and cooling is generally not required.
