WARNING: To reduce the risk of personal injury or damage to the equipment,
adequately stabilize the rack before extending a component outside the rack. Extend
only one component at a time. A rack may become unstable if more than one
component is extended.
WARNING: To reduce the risk of personal injury or damage to the equipment:
• Extend the leveling jacks to the floor.
• Rest the full weight of the rack on the leveling jacks.
• Attach the stabilizers to the rack if it is a single rack installation.
• Couple the racks together in multiple rack installations.
WARNING: When installing the server blade enclosure in a telco rack, adequately
secure the rack frame to the building structure at the top and bottom.
WARNING: To reduce the risk of personal injury or damage to the equipment, use two
or more people to safely unload the rack from the pallet. An empty 42U rack weighs
115 kg (253 lb), is over 2.1 m (7 ft) tall, and may become unstable when moved on its
casters. Handle the rack from both sides as it rolls down the ramp from the pallet. Do
not stand in front of the rack.
CAUTION: Always begin by mounting the heaviest item on the bottom of the rack. Continue
to populate the rack from the bottom to the top.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives
and the internal system components to cool before touching.
WARNING: To reduce the risk of electrical shock or damage to the equipment:
• Plug the power cords into a grounded (earthed) electrical outlet that is easily
accessible at all times.
Unplug the power cord from each power supply to disconnect power to the
•
enclosure.
WARNING: Because the rack enables you to stack enclosure components in a vertical
rather than a horizontal plane, you must take precautions to provide for rack stability
and safety to protect both personnel and property. Heed all cautions and warnings
throughout the installation instructions that came with the enclosure.
WARNING: There is a risk of injury or damage to the equipment from hazardous
energy. The access door provides access to hazardous energy currents. The door
should remain locked during normal operation, or the server blade enclosure should be
installed in a controlled access location where only qualified personnel have access to
the system.
