Preparing for installation
Safety recommendations
To avoid possible bodily injury and equipment damage, read all safety recommendations carefully
before installation. Note that the recommendations do not cover every possible hazardous condition.
General safety recommendations
x
Keep the chassis clean and dust-free.
x
Do not place the switch on a moist area, and avoid liquid flowing into the switch.
x
Make sure that the ground is dry and flat and anti-slip measures are in place.
x
Keep the chassis and installation tools away from walk areas.
x
Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get

Electricity safety
x
Clear the work area of possible electricity hazards, such as ungrounded power extension cables,

x
Locate the emergency power-off switch in the room before installation so you can quickly shut power
off when an electrical accident occurs.
x
Unplug all external cables, including power cords, before moving the chassis.
