Rack 
CAUTION
 
 
 
Do not carry or install the rack only by a single person. 
 
 
At least two persons are required to carry or install the rack. Failure to follow this 
instruction may cause the rack to fall to result in personal injury and/or breakage of 
surrounding devices. In particular, a high rack (such as 44U rack) is unstable if it is 
not fixed by stabilizers. At least two persons must always carry or install the rack 
while they support it. 
 
 
Do not install the rack so that the load may be concentrated on a specific point. 
 
 
Install stabilizers on the rack or earthquake-resistant construction to the rack so that 
the total load of the rack and devices mounted on the rack is not concentrated on a 
single point. Join the racks in multiple-rack installations to distribute the load. 
Failure to follow this instruction may cause the rack to fall to result in personal 
injury. 
 
 
Do not install components on the rack only by yourself. 
 
 
At least two persons are required to install parts including the doors and trays for 
the rack. Failure to follow this instruction may cause some parts to fall to be broken 
and/or to result in personal injury. 
 
 
Do not leave more than one device being pulled out from the rack. 
 
 
Pulling out more than one device from the rack may cause the rack to be fallen. 
Only pull out a single device from the rack at a time. 
 
 
Do not provide the wiring for the rack to exceed the rating of the power supply. 
 
 
To prevent burns, fires, and device damages, the power supplied to the power 
supply in the rack shall not exceed the rating load of the power branch circuit. 
Contact the power constructor or local power company for the requirements on the 
wiring and installation of electric facilities.
