2-12 Installation PreparationPrecautionsTo avoid any device impairment and body injury resulting from improper use, please take the followingprecautions:z Before cleaning the switch, disconnect the power. Do not clean the switch with wet cloth or liquid.z Keep the switch away from water or dampness. Prevent water or moisture from entering the switchchassis.z Do not place the switch on an unstable case or desk, because the switch might be damagedseverely in case of a fall.z Keep the switch room drafty and the switch ventilation hole free of obstruction.z The switch can operate normally only under correct voltage input. Make sure that the operatingvoltage is consistent with that labeled on the switch.z To prevent electric shock, do not open the chassis while the switch is operating, and do not openthe chassis arbitrarily even when the switch is powered off.z Before changing interface cards, wear an ESD-preventive wrist strap to prevent the cards frombeing damaged by electrostatic discharge.Requirements on EnvironmentS3100 Series Ethernet Switches must be used indoors. When you install your switch in a cabinet or ona desk, you must ensure:z Enough space is reserved near the air-intake hole and the ventilation hole of the switch for heatdissipation of the switch chassis.z The cabinet or the workbench takes good ventilation and heat dissipation system.z The cabinet or the desk is solid enough to bear the weight of the switch and the accessories.z The cabinet or the desk is well grounded.To ensure normal operation and to prolong the life span of the switch, the following requirements on theinstallation site must also be satisfied.Temperature/Humidity RequirementsYou should keep your equipment room within the proper temperature and humidity ranges to ensure thenormal operation and working life of your switch. If the humidity in the equipment room is too high for along time, it may decrease the insulation attribute of insulating material or even cause electric leakageof insulating material, and, sometimes, may change the mechanical performance of material and causethe rustiness and corrosion of metal parts. If the relative humidity is too low, the captive screws maybecome loose due to the shrinking of insulation washers; in addition, electrostatic is more likely to beproduced in a dry environment, which may damage the circuit of the switch. High temperature maycause even greater damage to the switch. High temperature for a long time will speed up the aging ofinsulation material, greatly lower the reliability of the switch and greatly reduce the life span of theswitch.
