Safety recommendations
To avoid equipment damage or bodily injury, read the following safety recommendations before
installation. Note that the recommendations do not cover every possible hazardous condition.

•
Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.

•
Ensure good ventilation at the installation site and keep the air inlet and outlet vents of the
switch free of obstruction.
