Device Warnings And Precautions - HP 418800-B21 - StorageWorks Modular Smart Array 70 Storage Enclosure Maintenance And Service Manual

WARNING!
Verify that the AC power supply branch circuit that provides power to the rack is not overloaded.
Overloading AC power to the rack power supply circuit increases the risk of personal injury, fire, or
damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating.
Consult the electrical authority having jurisdiction over your facility wiring and installation requirements.
WARNING!
To reduce the risk of personal injury or damage to the equipment:
Observe local occupational safety requirements and guidelines for heavy equipment handling.
•
Obtain adequate assistance to lift and stabilize the product during installation or removal.
•
Remove all pluggable power supplies and modules to reduce the weight of the product.
•
Always load the heaviest item first, and load the rack from the bottom up. This makes the rack
•
"bottom-heavy" and helps prevent the rack from becoming unstable.
Extend the leveling jacks to the floor.
•
Rest the full weight of the rack on the leveling jacks.
•
Attach the stabilizing feet to the rack if it is a single-rack installation.
•
Ensure the racks are coupled in multiple-rack installations.
•
Fully extend the bottom stabilizers on the equipment. Ensure that the equipment is properly
•
supported/braced when installing options and boards.
Be careful when sliding rack components with slide rails into the rack. The slide rails could pinch
•
your fingertips.
Ensure that the rack is adequately stabilized before extending a rack component with slide rails
•
outside the rack. Extend only one component at a time. A rack may become unstable if more than
one component is extended for any reason.
Do not attempt to move a fully loaded equipment rack. Remove equipment from the rack before
•
moving the rack.
At least two people are needed to safely unload the rack from the pallet. An empty 42U rack weighs
•
115 kg (253 lb), is over 2.1 meters (7 ft) tall, and can become unstable when being moved on its
casters.
Do not stand in front of the rack as it rolls down the ramp from the pallet; handle it from the sides.
Stabilize the device by keeping the unit on the rails.

Device warnings and precautions

CAUTION:
System power to the MSA70 does not shut off completely with the power supply buttons. The LCD
indicators on the front panel power buttons should be considered as on and standby, rather than on and
off. The standby position removes power from most of the electronics and the hard drives, but portions of
the power supplies and some internal circuitry remain active.
To remove all power from the system, you must disconnect the power cord from the enclosure.
•
In systems with multiple power supplies, you must disconnect all the power cords to remove power
•
completely from the enclosure.
WARNING!
To reduce the risk of personal injury or damage to the equipment, observe local occupational health and
safety requirements and guidelines for manually handling material.
