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
scene.
