מתג מנוהל WEB עם 48 פורטים במהירות 10/100Mbps, שני פורטים ג'יגהביט ושתי יציאות משולבות ג'יגהביט/אופטי (SFP)


The DES-1210-28/52 Web Smart Switch is equipped with 24 or 48 10/100 Mbps ports, 2 10/100/1000BASE-T ports, and 2 combo 10/100/1000BASE-T/SFP ports. The DES-1210-28/52 integrates advanced management and security functions for enhanced performance and scalability. Support for IPv6 management and configurations ensure your network remains protected after the upgrade from IPv4 to IPv6. Management options including SNMP, Web Management, D-Link Network Assistant Utility, and Compact Command Line also make deployment easier. The DES-1210-28/52 provides a complete and affordable solution that is ideal for small and medium businesses and the enterprise edge.
Seamless Integration
The Web Smart Switch is designed to provide SMB users with complete control over their network. With Ethernet and Gigabit copper ports capable of connecting to existing CAT5 twisted-pair cables, these switches eliminate the need for complex reconfiguration. The DES-1210-28/52 allows for flexible connections to a backbone or server. Additionally, all ports support auto-negotiation of MDI/MDIX crossover, eliminating the need for crossover cables or uplink ports.
Extensive Layer 2 Features
Equipped with a complete lineup of L2 features, these switches include IGMP Snooping, Port Mirroring, Spanning Tree, and Link Aggregation Control Protocol (LACP). IEEE 802.3x Flow Control allows servers to directly connect to the switch for reliable data transfer. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shuts down the affected port. Cable Diagnostics allow network administrators to quickly examine the quality of the copper cables and also determine the type of cable error.
QoS, Bandwidth Control
The DES-1210-28/52 supports Auto Surveillance VLAN (ASV), and Auto Voice VLAN, which are best suited for video surveillance and VoIP deployments. Auto Surveillance VLAN is a new, industry-leading technology that consolidates surveillance video transmission and data through a single Web Smart Switch, thus sparing businesses the expense of dedicated hardware and facilities. ASV also ensures the quality of real-time video for monitoring and control without compromising the flow of conventional network data. The Auto Voice VLAN technology enhances the VoIP service by automatically routing voice traffic from an IP phone to an assigned VLAN. With higher priority and a dedicated VLAN, these features guarantee the quality and security of VoIP traffic. Furthermore, the DSCP markings on Ethernet packets enable different levels of service to be assigned to network traffic. As a result, these voice and video packets take precedence over other packets. In addition, with bandwidth control network administrators can reserve bandwidth for important functions that require a larger bandwidth or might have high priority.
Secure Your Network
D-Link’s innovative Safeguard Engine protects against traffic flooding caused by virus attacks. The DES-1210-28/52 also supports 802.1X port-based authentication, allowing the network to be authenticated through external vRADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and protects the internal IT network. The DES-1210-28/52 supports ARP Spoofing Prevention, which prevents the network from being cut off or leaves dropped by hackers using faked ARPs that pretend to be PCs, servers, routers, or gateways. For added security, DHCP Server Screening filters rogue DHCP server packets from user ports to prevent unauthorized IP assignment.
Versatile Management
The DES-1210-28/52 provides a D-Link Network Assistant Utility that enables administrators to remotely control their network down to the port level. The D-Link Network Assistant Utility allows customers to easily discover multiple D-Link Web Smart Switches within the same L2 network segment. With this utility, users do not need to change the IP address of their PC, and the initial setup of the switches will be greatly simplified. Switches within the same L2 network segment that are connected to the user’s PC are displayed on-screen for instant access. This allows extensive switch configuration and basic setup of discovered devices, including password changes and firmware upgrades. The DES-1210-28/52 also supports D-View 6.0 and Compact Command Line Interface (CLI) through Telnet. D-View 6.0 is a network management system that allows for the central management of critical network characteristics such as availability, reliability, resilience, and security.
