Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible hazardous
condition.
Before cleaning the switch, unplug all power cords from the switch. Do not clean the switch with wet
cloth or liquid.
Do not place the switch near water or in a damp environment. Prevent water or moisture from entering
the switch chassis.
Make sure that the ground is dry and flat and anti-slip measures are in place.
Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of
a fall.
Keep the chassis and installation tools away from walk areas.
Do not wear loose clothing, jewelry (for example, necklace), or any other objects that could get caught
in the chassis when you install and maintain the switch.
To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is
just powered off.
Examining the installation site
The A3100 v2 Switch Series must be used indoors. To ensure normal operation and long service life of your
switch, install it in an environment that meets the requirements described in the following subsections.
Electricity safety
Clear the work area of possible hazards, such as ungrounded power extension cables, missing safety
grounds, and wet floors.
Make sure that the operating voltage is as required.
Locate the emergency power-off switch in the room before installation. Shut the power off at once in
case accident occurs.
Unplug all the external cables (including power cords) before moving the chassis.
Always check that the power has been disconnected.
ESD prevention
To prevent the electronic components from being damaged by the electrostatic discharge (ESD), you should
not only take ESD measures where the switch is located, but also take the following precautions:
Make sure the switch is well grounded. For how to ground the switch, see ―
