UltraSCSI RAID Enclosure 8–1
8
Enclosure Blowers
Ensuring proper UltraSCSI RAID enclosure operation requires
establishing and maintaining the proper operating environment.
Meeting the temperature and humidity ranges specified in
Appendix A involves using air conditioning to establish and maintain
the proper external, that is, ambient, environment. Failure to achieve
these goals might cause components to malfunction and compromise
data integrity.
The eight blower assemblies on the rear of the enclosure (see Figure
8–1) are an integral part of the enclosure and ensure that the
components remain cool. These blowers are arranged in two banks of
four blowers each. Air flow provided by these blowers is sufficient for
proper operation of the UltraSCSI subsystem.
