l

The power supply voltage of the device must meet the requirements on the input voltage

of the device.

l

Keep power plugs clean and dry to avoid electric shocks or any other hazards.

l

Dry your hands before removing or inserting cables.

l

Stop the device and switch off the power before removing or inserting cables.

l

Switch off the power and remove all the cables, including the power cable, optical fibers,

and network cables, from the device during periods of lightning activity.

l

Switch off the power and remove the power plug if the device needs to be shut down for a

long time.

l

Protect the device from ingress of water or other liquids. If such an accident occurs, switch

off the power immediately and remove all the cables, including the power cable, optical

fibers, and network cables, from the device. Contact the specified service center in the case

of a device failure.

l

Do not stamp, pull, drag, or excessively bend the cables because they may get damaged.

Damaged cables can cause a device failure.

l

Do not use the cables that are damaged or have deteriorated.

l

Do not look directly into the optical port on the device without eye protection. The laser

emitted from the optical port can injure your eyes.

l

In case of any abnormalities, such as smoke, abnormal sound, or odor from the device,

immediately stop the device, switch off the power, and remove all cables, including the

power cable, optical fibers, and network cables, from the device. Contact the specified

service center in the case of a device failure.

l

Prevent foreign objects such as metal objects from dropping into the device through the

heat dissipation mesh.

l

Protect the outer case of the device from scratches, because the paint that peels off in the

scratched areas can cause device abnormalities. If the paint falls into the device it may cause

short circuits. In addition, peeled-off paint can cause an allergic reaction to the human body.

l

Ensure that the device is kept out of the reach of children. Guard against risks such as

children playing with the device or swallowing small parts of the device.

Instructions for Cleaning

l

Before cleaning the device, stop the device from running, switch off the power, and remove

all cables, including the power cable, optical fibers, and network cables, from the device.

When inserting and removing optical fibers, keep the optical fiber connectors clean.

l

Do not use cleaning fluid or spray-on detergent to clean the outer case of the device. Use

a soft cloth instead.

Instructions for Environment Protection

l

Put the retired device and batteries at the specified recycle place.

l

Abide by local laws and regulations to handle packaging materials, run-out batteries and

retired devices.

2.1 Product Introduction

This topic provides the appearance and describes the ports and LEDs of the HG8240/HG8245/

HG8247.

The HG8240/HG8245/HG8247 is an indoor optical network terminal (ONT) designed for home

users and small office and home office (SOHO) users. Its upper shell adopts the natural heat

dissipation material, and its optical port adopts the dust-proof design with a rubber plug. The

HG8240/HG8245/HG8247 is eye-pleasing and energy-efficient. It can be deployed on a

workbench or mounted on a wall, meeting users' deployment requirements in different scenarios.

By using the gigabit-capable passive optical network (GPON) technology, the HG8240/

HG8245/HG8247 provides a high-speed data channel through a single optical fiber with an

upstream rate of 1.244 Gbit/s and a downstream rate of 2.488 Gbit/s. In this way, you can enjoy

quality high-speed data service, voice service, and video service. In addition, the HG8245 and

HG8247 provide reliable wireless access service, and convenient storage and file sharing

services within a home network.

As an ONT, the HG8240/HG8245/HG8247 provides convenient and efficient remote

management functions. The HG8240/HG8245/HG8247 supports the TR-069 and ONT

Management and Control Interface (OMCI) protocols and manages all home terminals in a

unified manner, thus implementing remote fault diagnosis, service provisioning, and

performance statistics measurement.
