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.
Device Warnings and Cautions
WARNING:
To reduce the risk of personal injury from hot surfaces, allow
the hot-plug drives and the internal system components to cool before
touching.
WARNING: To reduce the risk of electrical shock or damage to the
equipment:
•
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.
•
Unplug the power cord from each power supply to disconnect power
to the equipment.
WARNING: Because the rack allows you to stack computer 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 device.
CAUTION:
Protect the device 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:
Do not operate the device for extended periods without the access
panel. Operating the device without the access panel results in improper airflow
and improper cooling that can lead to thermal damage.
