Small businesses form a cost-effective network. Supports the SmartLink power management function, which enables the PoE port priority mechanism to be powered off when the system is overloaded, cuts off the power supply of the port with the lower priority and lower priority, ensures that the critical equipment is preferentially powered, and the switch is overloaded run to protect the switch.

Smart PoE Power Supply
Featuring multiple 10/100/1000Mbps PoE ports which support IEEE 802.3af/at protocol , the PoE Switch Series provides maximum power budget of 120W for all PoE ports and 30W for every single PoE port respectively, allowing users to have several different camera variations configured. 

Efficient Secure Management Interface
For efficient management, the Benchu Group HX308GPM series managed PoE switch is equipped with Web and SNMP management interfaces. The embedded Device Managed System (DMS) features provides users with the benefits of easy-to-use/configure/install/troubleshoot in the video surveillance, wireless access, and other SMBs and Enterprises applications. It is ideal to deliver management simplicity, better user experience, and lowest total cost of ownership.

Solution for IPv6 Networking

With the IPv6/IPv4 dual stack and other management functions with user-friendly interfaces, the HX308GPM are the best choices for IP surveillance, VoIP and wireless service providers to deploy the IPv6 network. More importantly, they help SMBs upgrade their network infrastructures to the IPv6 era without any monetary investment.

Robust Layer 2 Features

TheHX308GPM series can be programmed for advanced switch management functions, such as dynamic port link aggregation, Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The HX308GPM series allows the operation of a high-speed trunk combining multiple ports. It consists of a maximum of 9 trunk groups with 2 ports for each group, and supports connection fail-over as well.

Surge Protection
This PoE switch is based on the IEC61643-21:2000 standard,Reaching 6KV surge protection, the PoE ports owns the capacity to keep the PoE Switch from lightning strikes and other electrical surges, offering reliable performance even in some harsh environments.
