24Preparing for installationSafety recommendationsTo avoid any equipment damage or bodily injury caused by improper use, read the following safetyrecommendations before installing an H3C S5820X switch. Note that the recommendations do not coverevery possible hazardous condition.• Before cleaning the switch, unplug the power cord of the power module of the switch first. Do notclean the switch with 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. The switch might be severely damaged in caseof a fall.• Ensure proper ventilation of the equipment room and keep the ventilation vents of the switch free ofobstruction.• Connect the yellow-green protection grounding cable before power-on.• Make sure that the operating voltage is in the range labeled on the power module of the switch.• To avoid electrical shocks, do not open the chassis when the switch is operating or when the switchis just powered off.• When replacing interface cards, hot-swappable power modules and fan trays, wear anESD-preventive wrist strap to avoid damaging the units.Examining the installation siteThe H3C S5820X Switch Series must be used indoors. You can mount the switch in a rack or on aworkbench, but make sure:• Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.• The rack or workbench has a good ventilation system.• The rack is sturdy enough to support the switch and its accessories.• The rack or workbench is well earthed.To ensure normal operation and long service life of your switch, install it in an environment that meets therequirements described in the following subsections.Temperature/humidityYou must maintain a proper temperature and humidity in the equipment room. Long-term high humiditymay lead to bad insulation, electricity leakage, mechanical property changes, and metal corrosion.However, if the relative humidity is too low, captive screws may become loose as the result of contractionof insulation washers and static electricity may be produced in a dry environment to jeopardize thecircuits on the device. A high temperature is the most undesirable condition, because it accelerates theaging of insulation materials and significantly lowers reliability and service life of the switch.
