for any period negatively affects the system’s reliability and performance, and continued
operation for extended periods under such conditions might actually cause the system to shut
down.
The InServ Storage Servers can tolerate temperature and humidity fluctuations if the specified
guidelines are understood and followed. Exposure to conditions outside the specified ranges
may damage the system or its components.
Before a server is powered on, the air entering the subsystem must be clean and within the
ranges specified for temperatures and humidity. The room humidity must be kept sufficiently
low to prevent condensation on or within the subsystem, and must never exceed the limit
specified in the subsystem environmental requirements tables, including transients. The server
must never be exposed to conditions that could cause internal condensation to occur within
the subsystem.
CAUTION: Heated air from nearby equipment should not exhaust into the front
of the InServ Storage Server.
