Cost-optimized Managed Switch with Advanced L2/L4 Switching and Security PLANET GS-4210-16T2S is an ideal Gigabit Switch which provides cost-effective advantage to local area network and is widely accepted in the SMB office network. It offers intelligent Layer 2 data packet switching and management functions, friendly web user interface and stable operation. Besides the popular IPv6/IPv4 management and abundant L2/L4 switching functions, the GS-4210-16T2S comes with fanless feature and green technology to provide a quiet, energy-saving, high-speed and reliable office network environment.  The GS-4210-16T2S is equipped with 16 10/100/1000BASE-T Gigabit Ethernet ports and 2 additional 100/1000BASE-X SFP interfaces with inner power system. It offers a rack-mountable, affordable, safe and reliable Gigabit network switch solution for SMBs deploying networks, or requiring enhanced data security and network traffic management.     Cybersecurity Network Solution to Minimize Security Risks The GS-4210-16T2S supports SSHv2 and TLS protocols to provide strong protection against advanced threats. It includes a range of cybersecurity features such as DHCP Snooping, IP Source Guard, dynamic ARP Inspection Protection, 802.1x port-based network access control, RADIUS and TACACS+ user accounts management, SNMPv3 authentication, and so on to complement it as an all-security solution.     Redundant Ring, Fast Recovery for Critical Network Applications The GS-4210-16T2S supports redundant ring technology and features strong, rapid self-recovery capability to prevent interruptions and external intrusions. It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching) technology, Spanning Tree Protocol (802.1s MSTP) into customer’s network to enhance system reliability and uptime in various environments.     IPv6/IPv4 Dual Stack Management Supporting both IPv6 and IPv4 protocols, the GS-4210-16T2S helps the SMBs to step in the IPv6 era with the lowest investment as its network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up.      Robust Layer 2 Features The GS-4210-16T2S an be programmed for advanced switch management functions such as dynamic port link aggregation, 802.1Q VLAN and Q-in-Q VLAN, Multiple Spanning Tree protocol (MSTP), loop and BPDU guard, IGMP snooping, and MLD snooping. Via the link aggregation, the GS-4210-16T2S allows the operation of a high-speed trunk to combine with multiple ports such as a 16Gbps fat pipe, and supports fail-over as well.  Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2 protocol included to help discover basic information about neighboring devices on the local broadcast domain.   Efficient Traffic Control The GS-4210-16T2S is loaded with robust QoS features and powerful traffic management to enhance services to business-class data, voice, and video solutions. The functionality includes broadcast/multicast/unicast storm control, per port bandwidth control, 802.1p/CoS/IP DSCP QoS priority and remarking. It guarantees the best performance at VoIP and video stream transmission, and empowers the enterprises to take full advantage of the limited network resources.   Powerful Security PLANET GS-4210-16T2S offers comprehensive IPv4/IPv6 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 applications. Its protection mechanism also comprises 802.1X port-based user and device authentication, which can be deployed with RADIUS to ensure the port level security and block illegal users. With the protected port function, communication between edge ports can be prevented to guarantee user privacy. Furthermore, Port security function allows to limit the number of network devices on a given port.    Friendly and Secure Management  For efficient management, the GS-4210-16T2S is equipped with Command line, Web and SNMP management interfaces. With the built-in Web-based management interface, the GS-4210-16T2S offers an easy-to-use, platform-independent management and configuration facility. For text-based management, it can be accessed via Telnet and the console port. By supporting the standard SNMP protocol, the switch can be managed via any SNMP-based management software.   Moreover, the GS-4210-16T2S offers secure remote management by supporting SSHv2, TLSv1.2 and SNMP v3 connections which encrypt the packet content at each session.     Flexible Extension Solution The two mini-GBIC slots built in the GS-4210-16T2S are compatible with the 100BASE-FX/1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber transceiver to uplink to backbone switch and monitor center in long distance. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and to 10/20/40/60/80/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.   Fanless Design Adopting the latest chip process and green technology, the GS-4210-16T2S successfully reduces substantial power consumption with the fanless and noiseless design collocating with the effective cooler. Therefore, the GS-4210-16T2S is able to operate stably and quietly in any environment without affecting its performance.
