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.
•
Before cleaning the switch, remove 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.
•
Do not place the switch on an unstable case or desk.
•
Ensure good ventilation at the installation site and keep the air inlet and outlet vents of the
switch free of obstruction.
•
Make sure the power source voltage is as required.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•
To avoid ESD damage, wear an ESD wrist strap to hot-swap a power supply.
Examining the installation environment
To ensure correct operation of your switch, make sure the installation environment meets the
requirements listed in
Table1-2 Checking list for the installation environment
Item
Requirements
Ventilation and heat dissipation
CAUTION:
To ensure correct operation of your device, make sure the installation
environment is adequately ventilated to prevent the switch from
overheating.
•
Ensure a minimum clearance of 10 cm (3.94 in) around the chassis.
•
Do not install the device near a heat source, for example, a stove or
heater.
•
Ensure air ventilation in the installation environment.
•
Do not block the ventilation holes in the device or power adapter.
Anti-moisture
CAUTION:
Water or moisture might damage the circuits of the device.
•
Do not place the device near water or in a damp environment.
•
Install the switch in a clean, dry, and ventilated place where
temperature is controlled in a stable range.
•
Make sure the installation environment is free from water leakage or
condensation. If required, install a dehumidification device (such as
an air conditioner with a dehumidification function or a dedicated
dehumidifier).
•
Do not operate the device under or near the water source, such as
the wash basin, laundry room, or areas with high humidity.
•
Do not touch the device with wet hands.
Temperature/humidity
For correct operation and long service life of your switch, maintain the
temperature and humidity in the equipment room at acceptable ranges.
•
Lasting high relative humidity can cause poor insulation, electricity
leakage, mechanical property change of materials, and metal
corrosion.
