Power supply warnings and cautions
WARNING: To reduce the risk of electric 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 the power supply to disconnect power to the equipment.
•
Do not route the power cord where it can be walked on or pinched by items placed against it. Pay
particular attention to the plug, electrical outlet, and the point where the cord extends from the
server.
WARNING: To reduce the risk of injury from electric shock hazards, do not open power supplies. Refer
all maintenance, upgrades, and servicing to qualified personnel
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal
system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before beginning
any installation procedure. Improper grounding can cause electrostatic discharge.
CAUTION: Mixing different types of power supplies in the same server might:
•
Limit or disable some power supply features including support for power redundancy.
•
Cause the system to become unstable and might shut down.
To ensure access to all available features, all power supplies in the same server should have the same
output and efficiency ratings. Verify that all power supplies have the same part number and label color.
