Safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before installation. The recommendations do not cover every possible hazardous condition.
•To avoid damage to the electrolytic capacitor in the switch, do not store the switch without power for more than one year.
•Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with a 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.
•Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of a fall.
•Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.
•Make sure the operating voltage is in the required range.
•To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.
