6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

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.
Device warnings and precautions
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Allow the product to cool before removing covers and touching internal components.
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Disconnect power from the device by unplugging the power cord from either the electrical
outlet or the device.
• Do not use non-conductive tools that could bridge live parts.
• Remove all watches, rings, or loose jewelry when working in hot-plug areas of an energized
device.
• Install the device in a controlled access location where only qualified personnel have access
to the device.
• Power off the equipment and disconnect power to all AC power cords before removing any
access covers for non-hot-pluggable areas.
• Do not replace non-hot-pluggable components while power is applied to the product. Power
off the device and then disconnect all AC power cords.
• Do not exceed the level of repair specified in the procedures in the product documentation.
All troubleshooting and repair procedures are detailed to allow only subassembly or
module-level repair. Because of the complexity of the individual boards and subassemblies,
do not attempt to make repairs at the component level or to make modifications to any printed
wiring board. Improper repairs can create a safety hazard.
WARNING! To reduce the risk of personal injury or damage to the equipment, the installation
of non-hot-pluggable components should be performed only by individuals who are qualified in
servicing computer equipment, knowledgeable about the procedures and precautions, and trained
to deal with products capable of producing hazardous energy levels.
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.
