• Install a dust plug on the transceiver module to avoid damage to the transceiver module.
Examining the installation site
The H3C SR6602 router can only be used indoors. To ensure that the router works properly and to
prolong its service lifetime, the installation site must meet the following requirements:
• Temperature and humidity
• Cleanness
• EMI
Temperature and humidity
You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity
may 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 contraction
of insulation washers and static electricity may be produced in a dry environment to jeopardize the
circuits on the device. A high temperature is the most undesirable condition, because it accelerates the
aging 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 requirements
Item Temperature
Operating 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 requirements
Item Humidity
Operating humidity 10% to 95%
Storage humidity 5% to 95%
Altitude
Table 3 Altitude requirements
Item Altitude
Operating 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)
Cleanness
Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal
components and contact points, especially when indoor relative humidity is low. In the worst case,
electrostatic adsorption can cause communication failure.
