D-Link DGS-1210-48 Web Smart 48-Port Gigabit Switch

The DGS-1210-48 Web Smart switch with advanced management functions including SNMP, Web Management, SmartConsole Utility, and compact command lines provides a complete and affordable solution for small and medium businesses.
The D-Link DGS-1210-48 is the latest Web Smart switch to feature D-Link Green technology. Equipped with 44 10/100/1000Mbps ports and four combo 10/100/1000BASE-T/SFP ports, the DGS-1210-48 integrates advanced management and security functions that provide performance and scalability. Management options for the DGS-1210-48 include SNMP, Web Management, SmartConsole Utility, and Compact Command Lines, while also supporting ACL filtering and the D-Link Safeguard Engine. The DGS-1210-48 uses Auto Voice VLAN, ensuring higher priority for voice traffic. The DGS-1210-48 is equipped with two smart fans; these fans are set to low speed by default and will automatically switch to high speed once the temperature threshold has been reached.

D-Link Green
D-Link is continuously striving to take the lead in developing innovative technology that allows for power saving without sacrificing operational performance or functionality. The DGS-1210-48 automatically detects the length of connected cables and can adjust power usage by saving energy on shorter cable connections of up to 20 meters. Power saving by link status helps to further save energy by automatically switching ports without a link to sleep mode and thus drastically reducing power consumption. The DGS-1210-48 takes the approach to green IT and power saving one step further by incorporating a special chipset with advanced silicon technology.

Seamless Integration
The DGS-1210-48 comes with Ethernet and Gigabit copper 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 more flexible solution for upstream or downstream server connections via fiber interface. Using the default presets, the administrator can quickly set up 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, this switch includes 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 2000Mbps 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 determine the type of cable error.

QoS, Bandwidth Control
The DGS-1210-48 is perfect for deployment in a VoIP environment, as they support 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 higher priority.

Secure your Network
The innovative D-Link Safeguard Engine function protects the switches against traffic flooding caused by virus attacks. The switch can 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 helps to protect the internal IT network. The DGS-1210-48 includes ARP Spoofing Prevention, which protects from attacks on the Ethernet network that may allow an intruder to sniff data frames on a LAN, modify traffic, or bring traffic to a halt altogether by sending fake ARP messages to the network. To prevent ARP Spoofing attacks, the switch uses Packet Control ACLs to block invalid packets that contain fake ARP messages. For added security, the DHCP Server Screening feature screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment.

Versatile Management
The DGS-1210-48 provides a SmartConsole Utility and a web-based management interface that enable administrators to remotely control their network down to the port level. The SmartConsole 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 and it also provides an easy initial setting of the Smart 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 settings and basic configuration of discovered devices such as password changes and firmware upgrades. The DGS-1210-48 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 in a consistent way. CLI management through Telnet makes the adjustment of basic settings such as password changes or firmware and configuration file uploads possible.
