Do not carry or install alone.
Carry or install a rack with two or more people. If the rack is carried by one person,
the rack may fall and cause injury or damage to physical assets. A tall rack such as a
44 U rack, in particular, is unstable if it is not fixed by stabilizers. Make sure to
support the rack with two or more people to carry and/or fix it.
Do not install the rack in such a manner that weight is imposed on a single
spot.
Avoid concentration of weight loads of the rack and units installed on a single spot.
Use stabilizers or connect two or more racks to balance loads. If not, the rack may
fall over and cause injury.
Do not carry or remove parts alone.
Do not work alone to install or remove a part such as a rack door and tray. The part
may fall and be damaged, and there is a risk of injury.
Use a lifter to install a unit.
Use a lifter to install/remove a unit. Otherwise, the unit may fall and be damaged,
and there is a risk of injury especially when you are working with a tall rack (such as
44U rack).
Do not pull out a unit when the rack is not stabilized.
When you pull out a unit from the device, make sure that the rack is fixed (by using
stabilizers or quake-resistant engineering).
Do not pull out two or more units from the rack at the same time.
When two or more units are pulled out from the rack, the rack may fall over. Pull out
one unit at a time.
Do not install excessive wiring beyond the rated power supply.
To prevent burns, fires, and damage to the rack, make sure that the rated load of the
power branch circuit is not exceeded. For more information on installation and
wiring of power-related facilities, contact your electrician or local power company.
