Important Safeguards and Warnings

This section introduces content covering the proper handling of the device, hazard prevention, and

prevention of property damage. Read carefully before using the device, and comply with the

guidelines when using it.

Transportation Requirements

Transport the device under allowed humidity and temperature conditions.

Storage Requirements

Store the device under allowed humidity and temperature conditions.

Installation Requirements

●Do not connect the power adapter to the device while the adapter is powered on.

●Strictly comply with the local electrical safety code and standards. Make sure that the ambient

voltage is stable and meets the power supply requirements of the device.

●Personnel working at heights must take all necessary measures to ensure personal safety

including wearing a helmet and safety belts.

●Do not place the device in a place exposed to sunlight or near heat sources.

●Keep the device away from dampness, dust, and soot.

●Put the device in a well-ventilated place, and do not block its ventilation.

●Use an adapter or cabinet power supply provided by the manufacturer.

●The power supply must conform to the requirements of ES1 in IEC 62368-1 standard and be no

higher than PS2. Please note that the power supply requirements are subject to the device label.

●Do not connect the device to two or more kinds of power supplies, to avoid damage to the

device.

●The device is a class I electrical appliance. Make sure that the power supply of the device is

connected to a power socket with protective earthing.

●The device must be grounded by a copper wire with a cross-sectional area of 2.5 mm2and a

ground resistance no more than 4 Ω.

●Voltage stabilizer and lightning surge protector are optional depending on the actual power

supply on site and the ambient environment.

●To ensure heat dissipation, the gap between the device and the surrounding area should not be

less than 10 cm on the sides and 10 cm on top of the device.

●When installing the device, make sure that the power plug and appliance coupler can be easily

reached to cut off power.

Operation Requirements

●Do not disassemble the device without professional instruction.

●Operate the device within the rated range of power input and output.

●Make sure that the power supply is correct before use.

●Make sure the device is powered off before disassembling wires to avoid personal injury.

●Do not unplug the power cord on the side of the device while the adapter is powered on.

●Use the device under allowed humidity and temperature conditions.

●Do not drop or splash liquid onto the device, and make sure that there is no object filled with

liquid on the device to prevent liquid from flowing into it.

●This is a class A product. In a domestic environment this may cause radio interference in which

case you may be required to take adequate measures.

●Do not block the ventilator of the device with objects, such as a newspaper, table cloth or curtain.

●Do not place an open flame on the device, such as a lit candle.

Maintenance Requirements.

●Power off the device before maintenance.

●Mark key components on the maintenance circuit diagram with warning signs.

1 Overview

1.1 Introduction

Equipped with a high performance switching engine, the 16/24-Port Managed Gigabit Switch

performs optimally. It has low transmission delay, large buffer and is highly reliable. It also has a

strong switching capability and optimizes transmission performance when accessing Ultra HD

videos. With its full metal design, the device has great heat dissipation and is low power

consumption, working in environments ranging from –10°C to 55°C (+14°F to +131°F). With

protection against overvoltage, EMC and overcurrent from power input terminals, the switch

effectively resists interference from static electricity, lightning, and pulses. It also has powerful

network management functions, supporting IGMP Snooping, Link Aggregation, QoS, LLDP, STP/RSTP,

and network management methods based on SNMP such as web.

1.2 Features

●Layer 2 network management switch.

●Network redundancy: STP/RSTP.

●Supports manual link aggregation and LACP.

●Devices discovery based on LLDP.

●QoS (IEEE802.1p/1Q) to increase determinism.

●IGMP Snooping.

●Fanless design.

●EMC high protection design.

●Supports desktop and rack-mount installation.

1.3 Typical Application

Here uses the 24-Port Managed Gigabit Switch as the example to introduce the typical networking
