Rack installation best practices

In addition to industry-standard recommendations, consider the following:
• Locate the heaviest items, such as uninterruptable power supplies (UPS) and additional disk enclos-
ures near the bottom of the rack.
• To make cabling easy, install the disk enclosures below the controller enclosure in the rack.
• Install similar components next to each other in the rack. Because enclosures, switches, and servers
are of differing depths, if you have more than one of a device, mount those devices adjacent to
one another to accommodate working behind the rack.
WARNING!
To reduce the risk of personal injury or damage to the equipment, be sure that:
• At least two people lift the storage system during removal or installation, if the weight, exceeds
22.7 kg (50 lb). If the system is being loaded into the rack above chest level, a third person MUST
assist with aligning the system with the rails while the other two people support the weight of the
system.
• The leveling jacks on the rack are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component in a rack is extended at a time. A rack may become unstable if more than
one component is extended.
• To prevent damage and to ease insertion of the device into the rack, support the weight of the
device and keep it level when sliding it into the rack.
