Requirements for the product
Install the product on a fixed rack. Do not lean against the product or stand
on it. Do not install the product in a place with weak floors and walls.
Do not subject the product to excessive vibration. That can drop and fall the
product, leading to failure.
Installing the equipment in a rack
To install or remove the system equipment in or from the rack cabinet,
always get help from at least one other person or use tools. If the system
equipment has to be installed on 31U and above of the rack cabinet or it is
already installed there, call for maintenance personnel instead of attempting
to install or remove it. Defective installation may cause the system
equipment to fall, resulting in injury or equipment failure.
Using a rack cabinet
When using a rack cabinet, do not place anything on the system unit mounted
on the cabinet and do not use the top of the system unit mounted on the
cabinet as a work bench. A heavy object placed on top of the system unit on
the cabinet may fall, resulting in injury.
Locking the rail into place
Be sure to pull out the equipment until it locks into place. If not, the
equipment may move unexpectedly, which causes you to get injured such as
your finger caught in the gap.
Contact with metal edges
When moving the equipment or adding parts, take care not to hurt yourself
on the metal or plastic edges. You can wear cotton gloves to protect your
hands.
