Chapter 1. Precautions for Use (EN)
to installing the equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
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 attempt to carry or install the server alone.
At least two people are required to carry or install the rack. Otherwise, the rack may fall,
resulting in personal injury or damage to peripheral devices. In particular, tall racks such as a
44U rack become unstable unless steadied with a stabilizer. Make sure that two or more people
hold the rack to carry or install the rack.
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.
At least two people are required to install a rack door, rail, and other rack components. 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 unit from a rack that is not stable.
When pulling out a unit from the rack, make sure that the rack is stabilized (by using stabilizers
or quake-proof fixtures). Otherwise, the rack may fall, resulting in personal injury.
Do not pull out more than one unit from the rack.
Pulling out multiple units from the rack may cause the rack to fall, resulting in personal injury.
Pull out only one unit 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.
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.
