10Gbps Fiber Ports and Multiple Triple Speed Fiber Ports Deliver High-speed Networking  PLANET MGSW-28240F L3 24-Port 100/1000BASE-X SFP + 4-Port 10G SFP+ Metro Ethernet Switch is specially designed for service providers and enterprises to deliver high-speed networking over longer distances. Its SFP+ and SFP fiber optic ports can be connected to various fiber and Ethernet cables to extend switching functionality throughout the network.  The MGSW-28240F is capable of providing non-blocking switch fabric and wire-speed throughput as high as 158Gbps in the temperature range from -10 to 60 degrees C without any packet loss and cyclic redundancy check (CRC) error. It greatly simplifies the tasks of upgrading the enterprise LAN for catering to increasing bandwidth demands.       Flexible and Extendable Fiber Optic Ethernet Solution 10G Ethernet is a big leap in the evolution of Ethernet. Each of the 10G SFP+ ports in the MGSW-28240F supports triple speed, 10GBASE-SR/LR, 2500BASE-X and 1000BASE-SX/LX SFP transceiver modules. With its 4-port, 10Gbps and up to 24-port 1Gbps/2.5Gbps fiber optic Ethernet link capability, the administrator now can flexibly choose the suitable SFP and SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. The MGSW-28240F provides broad bandwidth and powerful processing capacity.    Front-access Interface Design  The Metro Ethernet Switch comes with a user-friendly front-access design to help technicians improve wiring and installation efficiency, whereas, in the traditional design, the power socket, console port and even some extension module were always placed on the rear of the product. When technicians are installing or maintaining the older switch model on the rack, they have to be careful with other surrounding online devices as the rear-end of the product cannot be seen clearly. With the front-access design, technicians can avoid messing with other nearby devices.   Layer 3 Routing Support The MGSW-28240F enables the administrator to conveniently boost network efficiency by configuring Layer 3 IPv4/IPv6 VLAN static routing manually, and the IPv4 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.   Network with Cybersecurity Helps Minimize Security Risks The MGSW-28240F comes with enhanced cybersecurity to fend off cyberthreats and cyberattacks, it supports SSHv2, TLSv1.2 and SNMPv3 protocols to provide strong protection against advanced threats. Served as a key point to transmit data to customer’s critical equipment in a business network, the cybersecurity feature of the MGSW-28240F protects the switch management and enhances the security of the mission-critical network without any extra deployment cost and effort.      Redundant Ring, Fast Recovery for Critical Network Applications The MGSW-28240F 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), and redundant power input system into customer’s industrial automation network to enhance system reliability and uptime in harsh factory environments. In a certain, simple Ring network, the recovery time of data link can be as fast as 10ms.     AC and DC Redundant Power to Ensure Continuous Operation The MGSW-28240F possesses a 100~240V AC power supply and dual 36~60V DC power supply utilized as redundant power supply to ensure its continuous operation. Its redundant power system is specifically designed to handle the demands of high-tech facilities requiring the highest power integrity. Furthermore, with the 36~60V DC power supply implemented, the MGSW-28240F can be applied as the telecom level device and placed in almost any difficult environment.   Digital Input and Digital Output for External Alarm The MGSW-28240F helps the network administrators efficiently manage the unexpected network situations by providing Digital Input and Digital Output for external alarm device on the front panel. The Digital Input can be used to detect and log the status of the external devices such as door intrusion detector. The Digital Output could be used to send alarm whenever the MGSW-28240F has port link-down or power failure.     IPv6/IPv4 Dual Stack and Layer 2 Capability Supporting both IPv6 and IPv4 protocols, the MGSW-28240F helps data centers, campuses, telecoms, and more to experience 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.  The MGSW-28240F 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 to Layer 4 QoS, bandwidth control and IGMP/MLD Snooping. Via the link aggregation of supporting ports, the MGSW-28240F allows the operation of a high-speed trunk to combine with multiple fiber ports and supports fail-over as well.     Powerful Network Security The MGSW-28240F offers a 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 applications. Its protection mechanism also comprises 802.1X 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.    Advanced IP Network Protection The MGSW-28240F 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 administrators can now construct highly-secure corporate networks with considerably less time and effort than before.   Excellent Traffic Control The MGSW-28240F is loaded with powerful traffic management and QoS features to enhance connection services by telecoms and ISPs. The QoS features include wire-speed Layer 4 traffic classifiers and bandwidth limit that are particularly useful for multi-tenant units, multi-business units, Telco and network service providers’ applications. It also empowers the industrial environment to take full advantage of the limited network resources and guarantees the best performance in VoIP and video conferencing transmission.   User-friendly and Efficient Switch Management For efficient management, the MGSW-28240F is equipped with command line, Web and SNMP management interfaces.  With the built-in Web-based management interface, it 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. It offers Cisco-like command that helps users don’t need to learn new command from these switches For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet content at each session for secure remote management. Moreover, the MGSW-28240F offers secure remote management by supporting SSHv2, TLSv1.2 and SNMPv3 connections which encrypt the packet content at each session.        Intelligent SFP Diagnosis Mechanism The MGSW-28240F supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
