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.
CAUTION:
Before replacing a hot-pluggable component, ensure that steps have been taken to prevent loss of data.
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 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 down 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 down
•
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.
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.
CAUTION:
To properly ventilate the system, you must provide at least 7.6 cm (3.0 in.) of clearance at the front and
back of the device.
