GWT71818 is a new generation Industrial PoE Managed Switch with 8-Port 10/100/1000Base-TX and 8-Port 1000Base-FX Fast SFP that provide stable and reliable Ethernet transmission offered by GWT, with high quality design and reliability. It is positioning in the broadband network intervention market, to offer and realize Ethernet data exchange, convergence and long-distance optical transmission with efficient bandwidth and reliable fiber optic network solutions for users. The industrial switch complies with various characteristics such as mini size, no fan, low power consumption, high reliability and stability, and easy to maintain.

GWT71818 can offer redundant mechanisms for critical applications that need always-on connections. It can also operate either at standard operating temperature range -40 to 75°C. Housed in rugged DIN rail or wall mountable IP40 enclosures, these switches are perfect choices for harsh environments, such as industrial networking, intelligent transportation systems (ITS) and are also suitable for many
military and utility market applications where environmental conditions exceed commercial product specifications.


High Heat Dissipation Design For Prolong Life

Aluminum case for better heat dissipation and industrial grade temperature -40°~75°, also, the casing is IP40 dust proof and DIN Rail mountable, good for outdoor applicaiton.

Thermally conductive pad connected to PoE and main chipset, and the both side chipset is closely fit to the aluminum case, and the casing is striping style to get the most dissipation performance, so the whole design is very precise and delicate.


R&D User-Friendly Software


Active SNMPv3, RMON, and Dynamic Host Control Protocol (DHCP). This gives the IT department the ability to add the managed switch to the network, communicate to the managed switch using SNMP, monitor remote traffic and notifications using RMON, and automatically configure IP addresses of the switch and end devices.

GUI Management

Provides users with an intuitive and easy-to-use interface and immediate visual feedback, a GUI also allows a user to open up multiple programs or instances and displays these simultaneously.
The ease of use of GUIs has made it possible for the public in general, regardless of experience or knowledge, to access all kinds of systems for everyday use.


Supports redundant ring technology and features strong, rapid self-recovery capability to prevent interruptions and external intrusions.
ERPS has a few distinct advantages over RSTP and MSTP. The most obvious is convergence time. Beyond that, the G.8032 protocol is the most universal of the three, and it is available on a wider range of hardware.

There is no theoretical limit on the number of rings that can be added to a network. So as long as you have sufficient bandwidth, you can keep adding nodes.


High Effective PoE+ Solution Especially Suitable For Security Monitoring

Three POE Mode

Disabled , Enable POE , Enabled POE+.Provide both 15.4-watt IEEE 802.3af devices and 30-watt IEEE 802.3at devices without power-socket restriction to provide high-speed transmissions at the same time.

PoE Timing Function

PoE schedule and timing for each PoE port, to extend switch life and reduce power consumption by setting a priority mode for each port. which is a powerful function to help SMBs or enterprises save power and budget. It also increases security by powering off PDs that should not be in use during non-business hours.
