Reset

Use the button to restore the router to the factory defaults. With the router powered

on, use a pin to press and hold the Reset button (about 4~5 seconds). After the

SYS LED goes out, release the Reset button. If the SYS LED is flashing with a high

frequency about two or three seconds, it means the router is restored successfully.

To avoid any device damage and bodily injury caused by improper use, please observe

the following rules.

Safety Precautions

■

Keep the power off during the installation.

■

Wear an ESD-preventive wrist strap, and make sure that the wrist strap has a good

■

skin contact and is well grounded.

Use only the power cord provided with the router.

■

Make sure the operating voltage of the power supply is the same one labeled on the

■

router.

Ensure the vent hole is well ventilated and unblocked.

■

Do not open or remove the cover of the router.

■

Before cleaning the device, cut off the power supply. Do not clean it by the waterish

■

cloth, and never use any other liquid cleaning method.

Site Requirements

■

To ensure normal operation and long service life of the device, please install it in an

environment that meets the requirements described in the following subsection.

Temperature/Humidity

ȭ

ȭ

Installation

Gigabit Load Balance Broadband Router

Please keep a proper temperature and humidity in the equipment room. Too high/low

humidity may lead to bad insulation, electricity leakage, mechanical property changes

and corrosions. Too high temperature may accelerate aging of the insulation materials

and can thus significantly shorten the service life of the device. For normal temperature

and humidity of the device, please check the following table.

Environment Temperature Humidity

Operating 0℃~ 40℃10% ~ 90%RH Non-condensing

Storage -40℃~ 70℃5% ~ 90%RH Non-condensing

Clearness

The dust accumulated on the router can be absorbed by static electricity and result

in poor contact of metal contact points. Some measures have been taken for the

device to prevent static electricity, but too strong static electricity can cause deadly

damage to the electronic elements on the internal circuit board. To avoid the effect of

static electricity on the operation of the router, please attach much importance to the

following items:

Dust the device regularly, and keep the indoor air clean.

■

Keep the device well grounded and ensure static electricity has been transferred.

■

Electromagnetic Interference

Electronic elements including capacitance and inductance on the device can be affected

by external interferences, such as conducted emission by capacitance coupling,

inductance coupling, and impedance coupling. To decrease the interferences, please

make sure to take the following measures:

Use the power supply that can effectively filter interference from the power grid.

■

Keep the device far from high-frequency, strong-current devices, such as radio

■

transmitting station.

Use electromagnetic shielding when necessary.

■

Lightening Protection

Extremely high voltage currents can be produced instantly when lightning occurs and

the air in the electric discharge path can be instantly heated up to 20,000℃. As this

instant current is strong enough to damage electronic devices, more effective lightning

protection measures should be taken.

Ensure the rack and device are well earthed.

■

Make sure the power socket has a good contact with the ground.

■

Keep a reasonable cabling system and avoid induced lightning.

■

Use the signal SPD (Surge Protective Device) when wiring outdoor.

■

Note: For detailed lightning protection measures, please refer to Chapter 3

Lightning Protection.

Installation Site

S

When installing the device on a rack or a flat workbench, please note the following

items:

The rack or workbench is flat and stable, and sturdy enough to support the weight of

■

5.5kg at least.

The rack or workbench has a good ventilation system. The equipment room is well

■

ventilated.

The rack is well grounded. Keep the power socket less than 1.5 meters away from the

■

device.
