Rack installation

Ambient temperature
The operating temperature of the rack ambient is greater than room ambient.
Therefore, this product and other optional devices must be installed in an environment
compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
Air Flow
Make air flow required for safe operation of this product and other units.
Loading of rack
Mount this product and other units onto the rack evenly. If the weight of units is shifted
to the right, the left, or the upper of the rack, the possibility of rack falling is increased.
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
Maintain the reliable earthing of mounted units.
Do not attempt to carry or install the product 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 product, 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 product, make sure the load on the
branch circuit that supplies power to the rack will not exceed the rated load.
