TS2900 Tape Autoloader Setup, Operator, and Service Guide
Product Environment
The TS2900 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 should 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. To ensure maximum longevity of your
library, locate the library away from dust, dirt, and airborne particulates:
• Keep the library away from high-traffic areas, especially if the floor is carpeted.
Carpeting harbors dust and people walking on the carpet can cause the carpet
fibers and the dust to become airborne.
• Keep the library out of printer/copier rooms because of toner and paper dust.
Additionally, do not store paper supplies next to the library.
• Keep the library away from moving air caused by doorways, open windows, fans,
and air conditioners.
Altitude (meters) 0 to 2,500 0 to 2,500 0 to 2,500
Note: The operating environment of the library must not conflict with the media storage
requirements. The library may be capable of operating at elevated temperatures for an
extended period, however, the temperature could 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 should be met. It should be assumed that media stored
in the library is approximately 2 degrees above ambient temperature when the library is
powered ON.
