The D-Link DGS-1210 Series Smart Managed Switches are the latest generation of switches to provide increased Power over Ethernet (PoE) output a range of physical interface types multiple management interfaces and advanced Layer 2 features. With all of these features combined the DGS-1210 Series provides a cost-efficient and flexible solution for expanding any business network.&lt;br /&gt;The DGS-1210 Series switches support 8 24 or 48 10/100/1000BASE-T ports. Each switch also supports an additional 2 or 4 Gigabit SFP ports for optical connections using multimode or singlemode SFP transceivers.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;PoE Support&lt;/b&gt;&lt;br /&gt;Five of the eight models in the DGS-1210 series family support Power-over-Ethernet capabilities simplifying deployments with IP cameras VoIP phones wireless access points and other powered devices. These models include the DGS-1210-10P DGS-1210-10MP DGS-1210-28P DGS-1210-28MP and DGS-1210-52MP. Using the switchs management interface an administrator can control various PoE functions such as remotely rebooting cameras or access points from anywhere on the network including over the Internet.&lt;br /&gt;The switches also support time-based PoE  an option that allows administrators to set a time window that determines when each ports PoE power is turned on and off. All PoE models support the IEEE 802.3af and 802.3at standards and each PoE power budget varies per model.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Advanced Features&lt;/b&gt;&lt;br /&gt;The DGS-1210 Series comes equipped with a complete lineup of L2 features including IGMP snooping port mirroring Spanning Tree Protocol (STP) 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 transfers.&lt;br /&gt;The DGS-1210 Series also supports advanced features such as static routing With static routing IP routes are manually entered into a routing table which allows for communication between different user groups in different VLAN segments in a network. The switch can directly handle inter VLAN routing using multiple interfaces making the network run faster and more efficiently. Because the switches can manage internal routing the network router can be assigned to handle external traffic routing only.&lt;br /&gt;Network maintenance features include loopback detection and cable diagnostics. Loopback detection significantly speeds up troubleshooting by automatically detecting and shutting down switching loops. The cable diagnostics feature designed primarily for administrators and customer service representatives determines the cable quality and quickly discovers errors allowing for hassle-free diagnostics and maintenance.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Automatic Configuration&lt;/b&gt;&lt;br /&gt;The DGS-1210 Series supports Auto Voice VLAN and Surveillance Mode which allow voice and video traffic to be automatically identified and handled differently to regular network traffic. Auto Voice VLAN detects Voice over IP (VoIP) traffic and automatically segments it from the rest of the network increasing security and allowing Quality of Service (QoS) to be applied.&lt;br /&gt;Surveillance Mode detects compatible ONVIF cameras and places them in a surveillance VLAN allowing a single switch to be used for voice video and data removing the need for dedicated hardware and reducing maintenance costs. Surveillance Mode also includes its own Web UI making surveillance features easily accessible and simplifying management of your surveillance network.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Secure Your Network&lt;/b&gt;&lt;br /&gt;D-Links innovative Safeguard Engine protects the switches against traffic flooding caused by malicious attacks. The DGS-1210 Series supports 802.1X port-based authentication allowing the network to be authenticated through external RADIUS servers. The Access Control List (ACL) feature enhances network security and helps to protect the internal IT network. The DGS-1210 Series also features Address Resolution Protocol (ARP) spoofing prevention which provides protection from attacks on the network that could allow an intruder to sniff data frames modify traffic or bring traffic to a halt altogether by sending fake ARP messages. 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 filters DHCP replies on unauthorized ports to prevent them from being assigned an IP address.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Versatile Management&lt;/b&gt;&lt;br /&gt;The DGS-1210 Series comes with the D-Link Network Assistant (DNA) utility that enables administrators to remotely control their network down to the port level. The D-Link Network Assistant utility furthermore allows customers to easily discover multiple D-Link Smart Managed Switches within the same L2 network segment and display them onscreen for instant access. With this utility users do not need to change the IP address of their PC. This allows for simultaneous configuration and basic setup of all discovered devices including password changes and firmware upgrades.&lt;br /&gt;The DGS-1210 Series also supports D-View 7.0 and Command Line Interface (CLI) through Telnet. D-View 7.0 is a network management system that allows for the central management of critical network characteristics such as availability reliability resilience and security.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Lifetime Warranty and NBD Replacement&lt;/b&gt;&lt;br /&gt;D-Link offers a Lifetime Warranty and Next Business Day (NBD) hardware replacement on the DGS-1210 Series Gigabit Smart Managed Switches to further its commitment to product quality and long-term customer confidence.
