Notes:
• See Figure 4-3 on page 4-53 for the location and load of each VTSS cabinet support point.
• Values assume 15 lb./ft
2
(73 kg/m
2
) superimposed dead load over entire area for raised floor, cables, etc., and
15 lb./ft
2
(73 kg/m
2
) live load for personnel and equipment in clearance areas between units.
• Loading of adjacent floor areas must be considered when evaluating overall floor capacity.
• To evaluate floor loading for other possible configurations, consult a structural engineer.
