General safety recommendations
•
Keep the router and installation tools away from walk areas.
•
Place the router in a dry and flat location and make sure anti-slip measures are in place.
•
Remove all external cables and power cords before moving the router.
Electricity safety
•
Locate the power-off switch in the equipment room before installation. Shut off the power
immediately if an accident occurs. Disconnect the power cord from the router if necessary.
•
Make sure the router is reliably grounded.
•
Do not remove and install the chassis cover when the router is operating.
•
Connect the interface cables correctly.
•
Use an uninterrupted power supply (UPS).
•
Do not work alone when the router has power.
•
Always make sure the power has been disconnected during the installation or replacement
procedure.
Examining the installation site
The router can only be used indoors. To ensure correct operation and a long lifespan for your router,
install it in an environment that meets the requirements described in the following subsections.
Temperature and humidity
Maintain the temperature and humidity in the equipment room as described in
.
•
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 cause problems
including loose mounting screws and circuit failure.
•
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the router.
