Environmental Requirements and Hazards

VSM5 system components are sensitive to corrosion, vibration, and electrical interference in enclosed environments such as data centers. Because of this sensitivity, equipment should not be located near areas where hazardous and/or corrosive materials are manu- factured, used, or stored, or in areas with above-average electrical interference or vibra- tion levels.

For best performance, equipment should be operated at nominal environmental condi- tions.If VSM5 system equipment must be located in or near adverse environments, addi- tional environmental controls should be considered (and implemented where practicable) to mitigate those factors prior to installation of the equipment.

Floor Construction Requirements

VSM5 system equipment is designed for use on either raised or solid floors. Carpeted sur- faces are not recommended since these retain dust and contribute to the buildup of poten- tially damaging electrostatic charges. A raised floor is preferable to a solid floor since it permits power and data cables to be located safely away from floor traffic and other poten- tial floor-level hazards.

Floor Loading Requirements

DANGER !!

Exceeding recommended raised-floor loads can cause a floor collapse, which could result in severe injury or death, equipment damage, and infrastructure damage. It is advisable to have a structural engineer perform a floor-load anal- ysis before beginning installation of VSM5 system equipment.

CAUTION !

When being moved, a VTSS cabinet creates almost twice the floor load as when static. To reduce floor load and stress, and the potential for damage or injury when moving a VTSS (e.g., during installation), consider using 19 mm/ 0.75 in. plywood on the floor along the path where the cabinet will be moved.

Flooring with an overall (superimposed) load rating of 490 kg/m2 (100 lbs./ft2) is recom- mended. If floors do not meet this rating, a site engineer or facilities manager must consult the floor manufacturer or a structural engineer to calculate actual loads and determine if the weight of a particluar VSM5 system configuration can be safely supported.

When being moved from one location to another, a VSM5-VTSS system cabinet gener- ates roughly twice the floor load as in a static state. Using 19 mm (0.75 in.) plywood along a transfer path reduces the rolling load produced by a cabinet.
