moving the rack over any bump (for example: door sills, ramp edges, carpet edges, or elevator
openings). When the rack is moved over a bump, there is a potential for it to tip over.
Moving the rack requires a clear, uncarpeted pathway that is at least 80 cm (31.5 in) wide for the
60.3 cm (23.7 in) wide, 42U rack. A vertical clearance of 203.2 cm (80 in) should ensure suf ficient
clearance for the 200 cm (78.7 in) high, 42U rack.
CAUTION:

damaging the rack.
Make sure that all four leveler feet are in the fully raised position. This process will ensure that the casters
support the rack weight and the feet do no impede movement.
Each 10000-Series rack requires an area 600 mm (23.62 in) wide and 1000 mm (39.37 in) d eep
