24/48-Port Web Smart Switch III D-Link′s DES-1210 Series is the latest generation of Web Smart Switches. Equipped with 24 or 48 10/100 Mbps ports, 2 10/100/1000BASE-T ports, & 2 combo 10/100/1000BASE-T/SFP ports, the series integrates advanced management & security functions that provide performance & scalability. While easy to use, the DES-1210 Series provides a complete & affordable solution for small & medium businesses. Management options for the switches include SNMP, Web Management, Smart Console Utility, & Compact Command Lines. The series also supports ACL filtering & D-Link′s Safeguard Engine. Furthermore, the DES-1210-28/52 uses Auto Voice VLAN, ensuring higher priority for voice traffic. Both models come with an innovative fanless design in 19" metal cases. Seamless Integration The Web Smart Switches are designed to provide SMB users a complete control over the network. With Ethernet & Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables, these switches eliminate the need for a complex reconfiguration process. The DES-1210 Series allows for flexible connection to a backbone or servers. in addition, all ports support auto-negotiation of MDI/MDIX crossover, or configurable auto MDI & therefore do away with crossover cables or uplink ports. This brings inexpensive & easy connectivity to your desktop. Extensive Layer 2 Features Equipped with a complete lineup of L2 features, these switches include IGMP Snooping, Port Mirroring, Spanning Tree & Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, 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 & Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port & automatically shut down the affected port. Cable Diagnostics is designed for network administrators to quickly examine the quality of the copper cables & also determine the type of cable error. Qo S, Bandwidth Control The switches are perfect for deployment in a Vo IP environment, as they support Auto Voice VLAN & Differentiated Services Code Point (DSCP) Qo S for Vo IP application. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN & by doing so enhance the Vo IP service. With a higher priority & individual VLAN, this feature guarantees the quality & security of Vo IP traffic. DSCP marks parts of an IP packet, enabling different levels of service to be assigned for network traffic. With Bandwidth Control, the network administrator 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 function protects the switches against traffic flooding caused by virus attacks. The switches support 802.1X portbased authentication, allowing the network to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security & helps to protect the internal IT network. With the IP-MAC-Port Binding (DHCP Snooping) feature, the switch snoops DHCP information in order to automatically learn IP-MACPort Binding pairs & create a white list. Whenever cyber crime or hacking attempts are found, the IP change is kept under control & the location of the IP address becomes traceable. For added security, the DHCP Server Screening feature screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment. Versatile Management The new generation of Web Smart Switches provides growing businesses simple & easy management of their network using an intuitive Smart Console utility or a web-based management interface that enables administrators to remotely control their network down to the port level. The Smart Console easily allows customers to 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 & it also provides an easy initial setting 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 extensive switch configuration settings & basic configuration of discovered devices such as password changes & firmware upgrades. The DES-1210 Series also supports D-View 6.0 & 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, & security in a consistent way. D-View 6.0 provides a useful set of tools for network administrators who want to effectively manage device configurations, fault tolerance, performance, & security. CLI management of the switches is possible via Telnet. This makes the adjustment of basic settings like password changes or firmware & configuration file uploads possible.
