Preparing a Controlled Environment
Media and Hardware Environment
When planning the Spectra 12000 library installation, note that the
library, drives and media must be maintained in a controlled
environment. Environmental extremes cause erratic operation and
possible failures.
The Spectra 12000 library is typically mounted in a rack. Make sure the
temperature in the rack does not exceed the maximum ambient
operating temperature of the library and that the library is well ventilated
with adequate air flow at all times.
Library operating specifications are:
Š Temperature: +35°F to +86°F (+2°C to +30°C)
Š Relative humidity: 20 percent to 80 percent (non-condensing)
Š Maximum wet bulb temperature: +77°F (+25°C)
Caution: Before using any new media, expose media to the
local operating environment for 24 hours. This lets the
media adjust to the local temperature and humidity.
See Specifications on page 161 for additional information on the drives
and media.
Air Quality
Large quantities of airborne particles can cause erratic operation of the
drives and library. The Spectra 12000 library comes with three intake air
filters on the inside of the front door to reduce the airborne particulates
in the library.
The table below shows the maximum amount of particulate
contamination per cubic foot and cubic meter of air that the library’s
