Chapter 2 Installation Preparation

2.1 Precautions

To avoid any device impairment and bodily injury because of
improper use, please take the following precautions:
Before cleaning the switch, pull out the power plug of the
switch. Do not clean the switch with wet cloth or liquid.
Do not place the switch near water or in a damp area.
Prevent water or moisture from entering the switch chassis.
Do not place the switch on an unstable case or desk,
because the switch might be damaged severely in case of a
fall.
Keep the switch room drafty and the switch ventilation hole
free of obstruction.
The switch can operate normally only under correct voltage
input. Make sure that the operating voltage is consistent with
that labeled on the switch.
To prevent electric shock, do not open the chassis while the
switch is operating, and do not open the chassis arbitrarily
even when the switch is powered off.
Before changing interface board, wear ESD-preventive wrist
strap to prevent the board from being damaged by
electrostatic discharge.
