Power supply warnings and cautions Power supply warnings and cautions
WARNING: 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, WARNING:
upgrades, and servicing to qualified personnel
CAUTION: Mixing different types of power supplies in the same server might: CAUTION:
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.
DC power supply warnings and cautions DC power supply warnings and cautions
WARNING: WARNING: To reduce the risk of electric shock or energy hazards:
This equipment must be installed by trained service personnel.
Connect the equipment to a reliably grounded secondary circuit source. A secondary circuit has no direct connection to
a primary circuit and derives its power from a transformer, converter, or equivalent isolation device.
The branch circuit overcurrent protection must be rated 27 A.
WARNING: To reduce the risk of electric shock, be sure that the cable grounding kit is properly installed and connected to a WARNING:
suitable protective earth terminal before connecting the power source to the rack.
CAUTION: This equipment is designed to permit the connection of the earthed conductor of the DC supply circuit to the CAUTION:
earthing conductor at the equipment. If this connection is made, all the following must be met:
This equipment must be connected directly to the DC supply system earthing electrode conductor or to a bonding
jumper from an earthing terminal bar or bus to which the DC supply system earthing electrode conductor is connected.
This equipment must be located in the same immediate area (such as adjacent cabinets) as any other equipment that
has a connection between the earthed conductor of the same DC supply circuit and the earthing conductor, and also the
point of earthing of the DC system. The DC system must be earthed elsewhere.
The DC supply source is to be located within the same premises as the equipment.
Switching or disconnecting devices must not be in the earthed circuit conductor between the DC source and the point of
connection of the earthing electrode conductor.
