W pewnej prostej sieci pierścieniowej czas odzyskiwania może być krótszy niż 10ms, aby szybko przywrócić sieć do normalnej pracy.Layer 3 Routing SupportThe GS-5220-48P4X series enables the administrator to conveniently boost network efficiency by configuring Layer 3 IPv4/IPv6 VLAN static routing manually, and the OSPFv2 (Open Shortest Path First) settings automatically. The OSPF is an interior dynamic routing protocol for autonomous system based on link state. The protocol creates a database for link state by exchanging link states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.Cybersecurity Network Solution to Minimize Security RisksThe cybersecurity feature included to protect the switch management in a mission-critical network virtually needs no effort and cost to install. The SSHv2 and TLSv1.2 protocols are utilized to provide strong protection against advanced threats. The network administrator can now construct highly-secure corporate networks with considerably less time and effort than before.Flexible and Extendable 10Gbps Ethernet SolutionEach of the SFP+ slot supports triple speed 10GBASE-SR/LR, 2500BASE-X or 1000BASE-SX/LX/BX, meaning the administrator now can flexibly choose the suitable SFP+/SFP transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. With its 4-port, 10Gbps Ethernet link capability, the GS-5220-48P4X series provides broad bandwidth and powerful processing capacity.Redundant AC/DC Power Supply to Ensure Continuous OperationThe GS-5220-48PL4XR are particularly equipped with one 100~240V AC power supply unit and one 36~60V DC power supply unit to provide an enhanced reliable and scalable redundant power supply. The continuous power system is specifically designed to fulfill the demands of high-tech facilities requiring the highest power integrity. With the 36~60V DC power supply, it is able to act as a telecom-level device that can be located in the electronic room.Convenient and Smart ONVIF Devices with Detection FeaturePLANET has newly developed an awesome feature -- ONVIF Support -- which is specifically designed for co-operating with Video IP Surveillances. From the GS-5220-48P4X series’ GUI, clients just need one click to search and show all of the ONVIF devices via network application. In addition, clients can upload floor images to switch and allows for deployment location of surveillance devices for easier inspection and planning. Moreover, clients can get real-time surveillance’s information and online/offline status, and also allows PoE reboot control from GUI.Centralized Power Management for Gigabit Ethernet PoE NetworkingTo fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the GS-5220-48P4X series features IEEE 802.3at PoE+ that combines up to 36 watts of power output and data per port over one Cat5E/6 Ethernet cable. It is designed specifically to meet the demand of higher power consuming network PD (powered device) such as IR, PTZ, speed dome cameras or even box-type IP camera with a built-in fan and heater. Compliant with both 802.3at and 802.3af PoE, it allows more flexibility in power requirement for a variety of PDs.Built-in Unique PoE Functions for Surveillance ManagementAs a managed PoE Switch for surveillance network, the GS-5220-48P4X series features four special PoE management functions:PD alive checkScheduled power recyclingPoE schedule PoE usage monitoringIntelligent Powered Device Alive CheckThe GS-5220-48P4X series can be configured to monitor connected PD status in real time via ping action. Once the PD stops working and has no response, the GS-5220-48P4X series 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 and reduce administrator management burden.Scheduled Power RecyclingThe GS-5220-48P4X series allows each of the connected PoE IP cameras to reboot at a specific time each week. Therefore, it will reduce the chance of IP camera crash resulting from buffer overflow.PoE Schedule for Energy SavingBesides IP surveillance, the GS-5220-48P4X series is certainly applicable to construct any PoE network including VoIP and wireless LAN. Under the trend of energy saving worldwide and contributing to environment protection on the Earth, the GS-5220-48P4X series 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 SMBs or enterprises save power and money.IPv4 and IPv6 VLAN Routing for Secure and Flexible ManagementTo help customer stay on top of business, the GS-5220-48P4X series does not only offer ultra high transmission performance, but also IPv4/IPv6 VLAN routing feature which allows to cross over different VLAN groups and IP addresses for the purpose of having a highly-secure, flexible management.Robust Layer 2 FeaturesThe GS-5220-48P4X series can be programmed for advanced switch management functions such as dynamic port link aggregation, Q-in-Q VLAN, private VLAN, Multiple Spanning Tree Protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The GS-5220-48P4X series provides 802.1Q tagged VLAN, and the VLAN groups allowed will be maximally up to 256. Via aggregation of supporting ports, the GS-5220-48P4X series allows the operation of a high-speed trunk combining multiple ports. The switch enables a maximum of up to 26 trunk groups with 4 ports for each trunk group and supports connection fail-over as well.Powerful Network SecurityThe GS-5220-48P4X series offers comprehensive Layer 2 to Layer 4 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 ports or defined typical network application. Its protection mechanism also comprises 802.1x Port-based and MAC-based customer and device authentication. As to private VLAN function, communications between edge ports can be protected to ensure customer privacy.Enhanced Security and Traffic ControlThe GS-5220-48P4X series also provides functions of DHCP snooping, IP source guard and dynamic ARP inspection so as to prevent IP from attacking and discarding ARP packets with invalid MAC address. The network administrators can now construct a highly-secure corporate network with considerably less time and effort than before.IPv6/IPv4 Dual StackAs the GS-5220-48P4X series supports the IPv6 Protocol, it helps SMBs and enterprises to step in the IPv6 era with the lowest investment, meaning the existing network facilities need not be replaced.Efficient and Secure ManagementFor efficient management, the GS-5220-48P4X series is equipped with console, Web and SNMP management interfaces. With the built-in Web-based management interface, the GS-5220-48P4X series offers an easy-to-use, platform-independent management and configuration facility.
