Examining the installation site
The routers can only be used indoors. To make sure the router operates correctly and to prolong its
service lifetime, the installation site must meet the following requirements:
Weight support
Make sure the floor can support the total weight of the router and accessories (such as the rack and
HIMs/MIMs). For the weight of the router and accessories, see "
."
Temperature and humidity
Maintain temperature and humidity in the equipment room in an acceptable range.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and bring problems
including loose screws and circuit failure.
•
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the router.
