Surge Protection
This 16 port gigabit 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.

Plug and Power Network Deployment
All of the RJ45 copper interfaces in this PoE switch support 10/100/1000Mbps auto negotiation for optimal speed detection through RJ45 Category 6, 5 or 5e cables. The standard auto-MDI/MDI-X support can detect the type of connection to any Ethernet device without requiring special straight-through or crossover cables.

High-quality , Configure-free 16 Ports Gigabit PoE+ Switch for System Integrators
Benchu group 16 port PoE switch SP5220-16PGE4GC, an ideal gigabit PoE switch, provides a cost-effective advantage to local area networks of SMBs. Offering Layer 2 data packet switching and stable operation, this model also complies with IEEE 802.3at Power over Ethernet Plus (PoE+) at an affordable price. The SP5220-16PGE is equipped with 16 10/100/1000BASE-T gigabit ethernet ports and 4 1000BASE-X SFP interfaces with inner power system. It's 16 Gigabit Ethernet ports are integrated with an 802.3at PoE+ injector function. It offers a rack-mountable, safe and reliable power solution for SMBs deploying Power over Ethernet networks. 

Energy-saving Design
Detect The 16 port gigbit poe switch (SP5200-16PGE4GC) uses new engine that incorporates two advanced Green Networking technologies:  

         ---- Idle Mode Link Down power savings

         ---- Intelligent use of power based on cable length

The Idle Mode Link Down power saving of the SP5200-16PGE4GC complies with IEEE 802.3az Energy Efficient Ethernet (EEE) standard to automatically lower power for a given port when it is not linked. The Intelligent use of power feature actively determines the appropriate power level based on the cable length. When connecting to the SP5200-16PGE4GC with Ethernet cable shorter than 20m, a device can obtain maximum power savings because the 16 port gigbit poe switch (SP5200-16PGE4GC) would automatically detect the Ethernet cable length and reduce power usage. The connected device can substantially reduce the overall power consumption, which makes a significant contribution to energy savings.

Flexibility and Extension Solution

The additional Four mini-GBIC SFP slots built in the switch support dual speed, 1000BASE-SX/LX SFP fiber-optic modules, meaning the administrator now can flexibly choose the suitable SFP transceiver according to not only the transmission distance but also the transmission speed required. The distance can be extended from 550 meters to 2km (multi-mode fiber) and to 20/40/60/100/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.

IEEE 802.3at PoE+ Compliant Power Source Switch
The PoE in-line power following the IEEE 802.3at/af standard makes the 16 port PoE switch (SP5220-16PGE4GC) able to deliver gigabit speed data and up to 30 watts of power per port to 16 PoE compliant powered devices (PDs) with a combined power output budget of up to 300 watts. The SP5220-16PGE4GC provides more flexibility in power requirement for all kinds of PDs with affordable installation costs.
