This symbol indicates the presence of a hot surface or hot component. If this surface
is contacted, the potential for injury exists.
WARNING: To reduce the risk of injury from a hot component, allow the surface to
cool before touching.
This symbol indicates that the component exceeds the recommended weight for one
individual to handle safely.
WARNING: To reduce the risk of personal injury or damage to the equipment,
observe local occupational health and safety requirements and guidelines for manual
material handling.
These symbols, on power supplies or systems, indicate that the equipment is
supplied by multiple sources of power.
WARNING:
To reduce the risk of injury from electric shock, remove all power cords
to completely disconnect power from the system.
Server warnings and cautions
WARNING:
This server is very heavy. To reduce the risk of personal injury or damage to the
equipment:
• Observe local occupational health and safety requirements and guidelines for manual
material handling.
• Get help to lift and stabilize the product during installation or removal, especially when the
product is not fastened to the rails. Hewlett Packard Enterprise recommends that a
minimum of two people are required for all rack server installations. A third person may be
required to help align the server if the server is installed higher than chest level.
•
Use caution when installing the server in or removing the server from the rack; it is unstable
when not fastened to the rails.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the power supply and some
internal circuitry remain active until AC power is removed.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply. 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 server for long periods with the access panel open or
removed. Operating the server in this manner results in improper airflow an
that can lead to thermal damage.
