1-2Safety recommendationsTo avoid equipment damage or bodily injury, read the following safety recommendations beforeinstallation. 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 switchwith wet cloth or liquid.• Do not place the switch near water or in a damp environment. Prevent water or moisture fromentering 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 theswitch 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 theswitch is just powered off.• To avoid ESD damage, wear an ESD wrist strap to hot-swap a power supply.Examining the installation environmentTo ensure correct operation of your switch, make sure the installation environment meets therequirements listed in Table1-2.Table1-2 Checking list for the installation environmentItem RequirementsVentilation and heat dissipationCAUTION:To ensure correct operation of your device, make sure the installationenvironment is adequately ventilated to prevent the switch fromoverheating.• 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 orheater.• Ensure air ventilation in the installation environment.• Do not block the ventilation holes in the device or power adapter.Anti-moistureCAUTION: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 wheretemperature is controlled in a stable range.• Make sure the installation environment is free from water leakage orcondensation. If required, install a dehumidification device (such asan air conditioner with a dehumidification function or a dedicateddehumidifier).• Do not operate the device under or near the water source, such asthe wash basin, laundry room, or areas with high humidity.• Do not touch the device with wet hands.Temperature/humidityFor correct operation and long service life of your switch, maintain thetemperature and humidity in the equipment room at acceptable ranges.• Lasting high relative humidity can cause poor insulation, electricityleakage, mechanical property change of materials, and metalcorrosion.
