3• Install a dust plug on the transceiver module to avoid damage to the transceiver module.Examining the installation siteThe H3C SR6602 router can only be used indoors. To ensure that the router works properly and toprolong its service lifetime, the installation site must meet the following requirements:• Temperature and humidity• Cleanness• EMITemperature and 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 router.For the temperature and humidity requirements of the router, see Table 1 and Table 2.Table 1 Temperature requirementsItem TemperatureOperating Temperature 0°C to 45°C (32°F to 113°F)Storage Temperature -40°C to 70°C(-40°F to 158°F)Table 2 humidity requirementsItem HumidityOperating humidity 10% to 95%Storage humidity 5% to 95%AltitudeTable 3 Altitude requirementsItem AltitudeOperating altitude –60 m (–196.85 ft) to 3 km (1.86 miles)Storage altitude –60 m (–196.85 ft) to 4.5km(2.8 miles)CleannessDust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metalcomponents and contact points, especially when indoor relative humidity is low. In the worst case,electrostatic adsorption can cause communication failure.
