• Third generation design, with improved management and security functions • Power-saving D-Link Green technology now in its 2nd generation • Smart fans set to low speed by default for further power savings • Solid security with 802.1X authentication and IP/MAC based Access Control Lists (ACL) • Malicious traffic and performance degradation prevention with D-Link Safeguard Engine™ • Auto Voice VLAN for the automatic prioritisation of digital voice traffic • Quality of service (QoS) and bandwidth control (down to 64 kbps) • High Reliability with Loopback Detection (LBD) and cable diagnostics • Simple Web based management • SmartConsole utility for the joint management of several switches The DGS-1210-48 is part of D-Link’s 3rd generation of Web Smart Switches that integrates advanced management and security functions for performance and scalability. With D-link Green technology now in its second generation, the DGS-1210-48 provides a complete, affordable and eco-friendly solution for small and medium businesses (SMB). Seamless Integration The DGS-1210-48 includes 48 10/100/1000 Mbps ports capable of connecting to existing Cat.5 twisted-pair cables. Additionally, the last four ports of the DGS-1210-48 combine SFP and copper connectivity into one port and therefore provide a flexible solution for server connections via fiber interface. Using the default presets, the administrator can quickly set up the switch without worrying about reconfiguring any settings and providing easy access for the user. 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). 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 and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shut down the affected port. Cable Diagnostics is designed for network administrators to quickly examine the quality of the copper cables and also determine the type of cable error. QoS & bandwidth control The switch is perfect for deployment in a VoIP environment, as it supports Auto Voice VLAN and Differentiated Services Code Point (DSCP) QoS for VoIP application. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service. With a higher priority and individual VLAN, this feature guarantees the quality and security of VoIP 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 unique Safeguard Engine function protects the switch against traffic flooding caused by virus attacks. The switch also supports 802.1X port-based authentication, allowing the network to be authenticated through an external RADIUS server. In addition, the Access Control List (ACL) feature enhances network security and helps to protect the internal IT network. The DGS-1210-48 includes ARP Spoofing Preventio
