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.
Moreover, the GS-4210-16T2S offers secure remote management by supporting SSHv2, TLSv1.2/TLSv1.3 and SNMP v3 connections which encrypt the packet content at each session.

Remote Management Solution
PLANET's Universal Network Management System (UNI-NMS) and NMSViewerPro/CloudViewerPro app support IT staff by remotely managing all network devices and monitoring PDs' operational statuses. Thus, they're designed for both the enterprises and industries where deployments of PDs can be as remote as possible, without having to go to the actual location once a bug or faulty condition is found. With the UNI-NMS or NMSViewerPro/CloudViewerPro app, all kinds of businesses can now be speedily and efficiently managed from one platform.

PLANET CloudNMS – Cloud-Based Universal Network Management
PLANET’s CloudNMS platform and mobile app empower IT staff to remotely manage all network devices and Powered Devices (PDs) in real time. Designed for enterprises and industries, CloudNMS minimizes the need for on-site troubleshooting by providing centralized monitoring, fault detection, and instant alerts.
With CloudNMS, businesses can manage diverse network deployments more efficiently, securely, and intelligently—all from a single cloud-based platform.

Flexible Extension Solution
The two slots built in the GS-4210-16T2S are compatible with the 100BASE-FX/1000/2500BASE-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 100 meters (RJ45 to SFP) or 300m and 500m (Multi-mode, LC) 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.
Intelligent SFP Diagnosis Mechanism
The GS-4210-16T2S supports SFP-DDM (Digital Diagnostic Monitor) function that can easily monitor real-time parameters of the SFP for network administrator, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

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.

High-performance Backbone/Server Farm Switch
Gigabit Ethernet supported equipment has become the fundamental unit of enterprises and network servers. With up to 42 Gbps non-blocking switch fabric, the GS-4210-16T2S can easily provide a local high bandwidth Gigabit Ethernet network for backbone of enterprises or telecoms. With its port trunking function, a 16 GB fat pipe is provided to connect to the backbone if required. It is ideal to be used as a server farm switch connecting to servers. The GS-4210-16T2S can offer the uplink to the edge network through Gigabit Ethernet LX/SX SFP modules with the two SFP ports.
FTTX/MAN Application
The GS-4210-16T2S applies the double tag VLAN (Q-in-Q) technology to providing low cost and easy operation for service providers carrying traffic for multiple customers across their networks. It features SNMP v3 and RMON Groups. The SNMP v3 security structure consists of security models, with each model having its own security levels. With two triple-speed SFP slots built in, the deployment distance of the GS-4210-16T2S can be extended up to 120 kilometers (single-mode fiber), which provides a high-performance edge service for FTTx solutions.
To build a network solution of FTTH (Fiber to the Home) or FTTC (Fiber to the Curb) for ISPs, and FTTB (Fiber to the Building) for enterprises, the various distances of SFP and Bidi (WDM) transceivers are optional for customers’ choices. For security and various applications, the 16 Gigabit ports of the GS-4210-16T2S can be configured with VLAN settings and connected to different units, offices, floors, houses and departments.
