Regulatory and Safety Notices

Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit and the
effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this
concern.
Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should
be given to supply connections other than direct connections to the branch circuit (e.g., use of
power strips).
Do not install with the load weight distributed unevenly
To avoid unevenly distributing the load of the rack and server, install a stabilizer or connect
multiple racks to distribute the weight. Otherwise, the rack may fall, resulting in personal injury.
Do not install components alone, and check the door hinge pins of the rack
Two or more people are required to install the rack components such as the door or rails. When
installing the door, make sure that both upper and lower hinge pins are held in place. Incomplete
attachment may cause components to fall off as well as personal injury.
Do not pull out any device from the rack that is not stabilized
When pulling out a device from the rack, make sure that the rack is stable (by using a stabilizer
or seismic reinforcement). Otherwise, the rack may fall, resulting in personal injury.
Do not pull out more than one device from the rack
Pulling out multiple devices from the rack may cause the rack to fall, resulting in personal
injury. Pull out only one device at one time.
Do not exceed the rated capacity of the power supply when connecting devices
To prevent burn injuries, fire, and damage to the server, make sure the load on the branch circuit
that supplies power to the rack will not exceed the rated load. For inquiries regarding the
installation or wiring of the power supply system, consult with the company that performed the
installation or wiring, or the power company that services your area.
Power supply and power cord use
Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to follow this warning
may cause an electric shock.
Do not connect the ground wire to a gas pipe.
Never connect the ground wire to a gas pipe. Failure to follow this warning may cause a gas
explosion.
