D-link DGS-1210-48

D-Link?s DGS-1210 Series is the latest generation of Web Smart Switches featuring D-Link Green Technology. The series integrates advanced management and security functions that provide
performance and scalability. Additionally, the DES-1210-10P?s 10/100/1000 Mbps ports are PoE-enabled,
offering ease-of-use and green features like timebased PoE, which allows for the power to be shut off
at a predetermined time. Compliant with 802.3af and 802.3at Pre-Standard, this switch is capable of feeding power to devices up to 30 Watts. Management options for the switches include SNMP, Web Management, SmartConsole Utility, and Compact Command Lines. The series also supports ACL filtering and D-Link?s Safeguard Engine. The DGS-1210 Series uses Auto Voice VLAN, ensuring higher priority for voice traffic. The DGS-1210-10P comes with a fanless design in a compact 13? desktop enclosure, the DGS-1210-16 and DGS-1210-24 feature a fanless design in 19? metal cases. The DGS-1210-48 is equipped with two smart fans which are set to low speed by default and will automatically switch to high speed once the temperature threshold is reached. A fanless design allows for quieter operation and guarantees an extended lifetime, while smart fans help to save power.

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

Seamless Integration
The DGS-1210 Series comes with Ethernet and Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables. Additionally, the last 2 or 4 ports of the DGS-1210 Series 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 the switch without reconfiguring any settings.

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. The Cable Diagnostic feature, designed primarily for adminstrators and customer service representatives, can rapidly discover the type of error and determine the cable quality.

QoS, Bandwidth Control
The switches are perfect for deployment in a VoIP environment, as they support Auto Voice VLAN and
Differentiated Services Code Point (DSCP) QoS for VoIP. 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, 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 the switches against traffic flooding caused by virus attacks. The switches also 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 and helps to protect the internal IT network. The DGS-1210 Series includes
ARP Spoofing Prevention, which protects from attacks on the Ethernet network that may allow an intruder to sniff data frames, 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 series provides a SmartConsole utility and a web-based management interface that enables 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. It also simplifies the initial setup
of the Smart Switches. 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 DGS-1210
Series 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. CLI management of the switches is possible via Telnet. This makes it possible to adjust basic settings, passwords, configuration files, and firmware with ease.
