28-pordiline PoE-ga Web Smart lüliti
Kust osta


The DES-1210 Series is the latest generation of D-Link Web Smart switches. 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 Series integrates advanced management and security functions for enhanced performance and scalability. The DES-1210-08P/28P are built with 10/100 Mbps ports that are PoE-enabled, offering ease-of-use and green features such as Time-based PoE, which can shut off PoE power at a predetermined time. The Smart Fan feature on the DES-1210-28P allows the built-in fans to automaticallyturn on at a certain temperature, providing continuous, reliable, and eco-friendly operation of the switch. Compliant with 802.3af and 802.3at, the DES-1210-28P is capable of feeding power of up to 30 watts to devices. Management options include SNMP, Web Management, SmartConsole Utility, and Compact Command Line for easy deployment. The DES-1210 Series provides a complete and affordable solution that is ideal for small and medium businesses and the enterprise edge.

Seamless Integration
The Web Smart switches are 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 Series allows for flexible connection 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. At 2000 Mbps full-duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss. 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 Series switches support Auto Surveillance VLAN (ASV) and Auto Voice VLAN for VoIP and video surveillance deployments. ASV ensures the quality of real-time video for monitoring and control without compromising the transmission of conventional network data. DSCP markings on Ethernet packets enable different levels of service to be assigned to network traffic. In addition, with Bandwidth Control, network administrators can reserve bandwidth for important functions that require more bandwidth or require high priority.

Secure Your Network
D-Link’s innovative Safeguard Engine protects against traffic flooding caused by virus attacks. These switches also support 802.1X port-based authentication, allowing the network to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and protects the internal IT network. The DES-1210 Series supports ARP Spoofing Prevention, which prevents the network from being cut off or eavesdropped by hackers using faked ARPs that pretend to be PCs, servers, routers, or gateways. For added security, DHCP Server Screening screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment.

Versatile Management
This new generation of Web Smart Switches provides growing businesses with simple and easy management of their network by using an intuitive SmartConsole utility and a web-based management interface that enables administrators to remotely control their network down to the port level. The SmartConsole 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 it also provides an easy setup of the Smart Switches.  Switches within the same L2 network segment that are connected to the user’s local PC are displayed on screen for instant access. This allows for extensive switch configuration settings and basic configuration (password changes and firmware upgrades) of discovered devices.

The DES-1210 Series supports D-View 6.0 and Compact Command Line Interface (CLI) control through Telnet. D-View 6.0 is a Network Management System that allows for central management of critical network characteristics and provides a useful set of tools for network administrators who want to effectively manage device configurations, fault tolerance, performance, and security. CLI management of switches is possible via Telnet, and allowing administrators to perform basic operations such as password changes, firmware upgrades, and configuration file uploads.
