Do not carry or install alone.
Carry or install a rack by two or more people. If the rack is carried by one person, the rack
may fall and can cause death or damage to physical assets. A tall rack such as a 44 U
rack, in particular, is unsuitable if it is not fixed by a stabilizer. Make sure to support the
rack by two or more people to carry and/or fix it.
Do not install the rack in such a manner that weights are imposed on a single spot.
Avoid concentration of weight loads of the rack and units installed on a single spot. Use
stabilizer or connect two or more racks to balance loads. If not, the rack may fall and can
cause injuries.
Do not carry or remove parts alone.
Do not work alone to install or remove a part such as rack door and tray. The part may fall
off and get damaged, and there is a risk of injuries.
Use a lifter to install a unit.
Use a lifter to install/remove a unit. If not, a unit may fall and get damaged. There is a risk
of injuries 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, ensure that the rack is fixed by using stabilizer or
quake-resistant engineering.
Do not pull out two or more units form the rack at the same time.
When two or more units are pulled out from the rack, the rack may fall. Pull out one unit at
the same time.
Do not install excessive wiring beyond the rated power supply.
To prevent burns, fires, and damage to the rack, ensure 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.
