Rack stability
Rack stability protects personnel and equipment.
WARNING!
To reduce the risk of personal injury or damage to equipment:
• Extend leveling jacks to the floor.
• Ensure that the full weight of the rack rests on the leveling jacks.
• Install stabilizing feet on the rack.
• In multiple-rack installations, fasten racks together securely.
• Extend only one rack component at a time. Racks can become unstable if more than one component
is extended.
