Centralized Power Management for Gigabit Ethernet PoE Networking
To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the SGS-5220-24P2X features high-performance Gigabit IEEE 802.3af PoE (up to 15.4 watts) and IEEE 802.3at PoE+ (up to 30 watts) on all ports. It perfectly meets the power requirement of PoE VoIP phone and all kinds of PoE IP cameras such as IR, PTZ, speed dome cameras or even box type IP cameras with built-in fan and heater for high power consumption.

The SGS-5220-24P2X’s PoE capabilities also help to reduce deployment costs for network devices as a result of freeing from restrictions of power outlet locations. Power and data switching are integrated into one unit, delivered over a single cable and managed centrally. It thus eliminates cost for additional AC wiring and reduces installation time.

Intelligent Powered Device Alive Check
The SGS-5220-24P2X can be configured to monitor connected PD (Powered Device) status in real-time via ping action. Once the PD stops working and it is without response, the SGS-5220-24P2X will resume the PoE port power and bring the PD back to work. It will greatly enhance the network reliability through the PoE port resetting the PD’s power source, thus reducing administrator management burden.

PoE Schedule for Energy Saving
Besides being used for IP surveillance, the SGS-5220-24P2X is certainly applicable to construct any PoE network including VoIP and wireless LAN. Under the trend of energy saving worldwide and contributing to the environmental protection on the Earth, the SGS-5220-24P2X can effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps you to enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help SMB or Enterprise save energy and money.

Solution for IPv6 Networking
With the support for IPv6 / IPv4 protocol, and easy and friendly management interfaces, the SGS-5220 series is the best choice for IP surveillance, VoIP and wireless service providers to connect with the IPv6 network. It also helps the SMB to step in the IPv6 era with the lowest investment but not necessary to replace the network facilities while the ISP constructs the IPv6 FTTx edge network.

Robust Layer2 Features
The SGS-5220 series can be programmed for advanced switch management function, such as dynamic port link aggregation, Q-in-Q VLAN, Multiple Spanning Tree Protocol(MSTP), Layer 2/4 QoS, bandwidth control andIGMP/MLD snooping. The SGS-5220 series allows the operation of a high-speed trunk combining multiple ports. Supporting 14 trunk groups, it enables a maximum of up to 8 ports per trunk and supports connection fail-over as well.

Powerful Security
The SGS-5220 series offers comprehensive layer2 to layer4 access control list (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP port number or defined typical network applications. Its protection mechanism also comprises802.1x Port-based and MAC-based user and device authentication. With the private VLAN function, communication between edge ports can be prevented to ensure user privacy.

Enhanced Security and Traffic Control
The SGS-5220 series also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrator can now construct highly secured corporate networks with considerably less time and effort than before.

Flexible and Extendable Solution
The 4 mini-GBIC SFP slots built in the SGS-5220-24P2X support dual speed as it features 100BASE-FX and 1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules. Now the administrator 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 up to 10/20/30/40/50/70/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
