Device Warnings And Precautions - HP 201723-B21 - StorageWorks Modular SAN Array 1000 Hard Drive 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.

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.
CAUTION:
Protect the installed solution from power fluctuations and temporary interruptions with a regulating
Uninterruptible Power Supply (UPS). This device protects the hardware from damage caused by power
surges and voltage spikes, and keeps the system in operation during a power failure.
