Floor requirements
The section specifies the required conditions of a floor on which a TS3500 Tape
Library is installed.
Install the library on a raised or solid floor. The floor must have a smooth surface
and, if raised, must not have ventilation panels beneath the leveling jackscrews. If
carpeted, ensure that the carpet is approved for computer-room applications.
To accommodate unevenness in the floor, you can raise or lower the leveling
jackscrews to the following specifications:
v Maximum allowable variance must not exceed 7 mm (.27 in.) per 76 mm (3 in.).
v Maximum out-of-level condition must not exceed 40 mm (1.6 in.) over the entire
length and width of the library.
The floor on which the TS3500 Tape Library is installed must be able to support:
v Up to 4.8 kilograms per square centimeter (68.6 pounds per square inch) of point
loads exerted by the leveling jackscrews
v Up to 211 kilograms per square meter (43.4 pounds per square foot) of overall
floor loading
The number of point loads exerted depends on the number of frames that make up
the library. There are four point loads per frame (located at the corners of each
frame).
