Router moving
CAUTION:
Do not hold the handle of the fan tray or power module, the handle on the rear cover of the chassis,
or the air vents of chassis to move the router. Doing so might cause equipment damage or even
bodily injury.
When moving the router, follow these guidelines:
•
When moving the router, hold the handles at both sides of the chassis.
•
Use at least two people to move the router.
•
Move the router carefully.
Examining the installation site
The router 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:
•
•
•
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.
For the temperature and humidity requirements of the router, see
