Table 8. Environmental specifications (continued)
Parameter Operating (see Note) Storage Shipping
Note: The operating environment of the library must not conflict with the media storage requirements. The library
can operate at elevated temperatures for an extended period. However, the temperature might shorten the useful
life of media that is stored in the library. If media is stored in the library for more than 10 hours, the storage
temperature requirements for media are met. It is assumed that media that is stored in the library is approximately
2 degrees above ambient temperature when the library is powered ON.

Product environment
The TL1000 Tape Autoloader is designed to operate in a general business environment.
The library meets the acoustical requirements for general business area category 2D. Category 2D states
that the library can be installed a minimum of 4 m (13 ft.) from a permanent work station.
To allow for service access, install the library a minimum of 0.9 m (3 ft.) from all obstacles.
The library is a precision computer peripheral device. To ensure maximum longevity of your library,
locate the library away from dust, dirt, and airborne particulates, as follows:
v Keep the library away from high-traffic areas, especially if the floor is carpeted. Carpeting harbors dust
and walking on the carpet can cause the carpet fibers and the dust to become airborne.
v Keep the library out of printer and copier rooms because of toner and paper dust. Additionally, do not
store paper supplies next to the library.
v Keep the library away from moving air caused by doorways, open windows, fans, and air
conditioners.
