•
Place the router in a dry and flat location and make sure anti-slip measures are in place.
•
Remove all external interface cables and power cords before moving the router.
Electricity safety
•
Locate the power switch of the power source before installation. Shut off the power
immediately if an accident occurs.
•
Make sure the router is reliably grounded.
•
Connect the interface cables correctly.
•
Use an uninterrupted power supply (UPS).
•
Always make sure the power has been disconnected during installation or replacement.
ESD prevention
WARNING!
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between a human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the router and the floor are reliably grounded.
•
Keep the equipment room clean to reduce the negative effects of dusts and particles.
•
Maintain the humidity and temperature levels in the acceptable range.
•
Always wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is
reliably grounded.
No ESD wrist strap is provided with the router. Prepare it yourself.
To attach an ESD wrist strap:
1.
Wear the wrist strap on your wrist.
2.
Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3.
Secure the wrist strap lock and the alligator clip lock together.
4.
Attach the alligator clip to the grounding screw on the router.
Examining the installation site
The router can only be used indoors. To ensure correct operation and a long lifespan for your
router, the installation site must meet the requirements in this section.
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 bring 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.
