Approximate system weights by configuration

Floor construction and floor loading

Calculate the floor loads for your server with the proceeding formulas. A floor loading assessment is the evaluation of the concrete sub floor and the raised floor. The weight of the raised floor is considered in the floor loading formula.

The building floor must support the weight of the equipment to be installed. The following pounds-per-square-foot (lb/ft²) and kilogram-per-square meter (kg/m²) formulas are used to calculate floor loading. For assistance with floor load evaluation, contact a structural engineer that satisfies your local requirements.

(Frame Weight [kg])/(Frame Area + (Service Area/2) [m²])) + ((75[kg]/m2) x Service Area[m²])/(Frame Area + (Service Area/2)[m²]) + (50 [kg]/m²)

(Frame Weight [lb])/(Frame Area + (Service Area/2) [ft²])) + ((15 [lb]/ft²) x (Service Area[ft²]/1)/Frame Area + (Service Area/2)[ft²]) + (10[lb]/ft²)

• Frame area equal 1.20 m² (12.9 ft²)
• Minimum service area equal 1.9 m² (20.6 ft²)
  Note: Limited to 1.52 m (60 in.) maximum from frame
• Maximum frame weight equal 1680 kg (3704 lb)

Floor loading formula notes

When the service clearance area is also used to distribute machine weight (weight distribution/service clearance), 75 kg/m² (15lb/ft²) is considered for personnel and equipment traffic. The distribution weight is applied over 0.5 of the service clearance up to a maximum of 760 mm (30 in.) as measured from the machine frame.

75 kg/[m²] x Service Area [m²]/1

15 lb/[ft²] x Service Area [ft²]/1

The raised-floor weight plus the cable weight adds 50 kg/m² (10 lb/ft²) uniformly across the total area used in calculations. (The total area is defined as: machine area + 0.5 service clearance.)
