The DGS‎-1210‎-28P Web Smart 28‎-Port PoE Gigabit Switch from D‎-Link features D‎-Link Green 3.0 Technology for increased energy efficiency‎.‎ This switch complies with the IEEE 802.3az Energy Efficient Ethernet Standard‎.‎ Support for IPv6 management and configurations ensure your network remains protected after the upgrade from IPv4 to IPv6‎.‎ By offering multiple management options‎,‎ the DGS‎-121028P allows for quick deployment‎,‎ infrastructure expansion‎,‎ and seamless upgrades‎.‎ Targeting small and medium sized businesses‎,‎ this Web Smart Switch provides functionality‎,‎ security‎,‎ and manageability for a fraction of the standard cost of ownership‎.‎ The DGS‎-1210‎-28P is a PoE Web Smart Switch that provides 24 10/100/1000 Base‎-T PoE ports with 4 Gigabit SFP ports‎.‎ In addition to IEEE 802.3af compliance‎,‎ ports 1‎-4 provides up to 30 watts of power output following IEEE 802.3at‎.‎ The design allows more flexibility in power allocation for a variety of powered devices with affordable installation costs‎.‎

Energy SavingThe DGS‎-1210‎-28P is capable of conserving power without sacrificing operational performance or functionality by using D‎-Link Green 3.0 technology‎.‎ Using the Energy Efficient Ethernet standard‎,‎ the network will automatically decrease the power usage when traffic is low with no setup required‎.‎ For environments not fully supporting the standard‎,‎ these switches offer advanced power‎-saving settings including port shutoff and standby‎,‎ LED shutoff‎,‎ and system hibernation based on custom time profiles‎.‎ The time profiles can also be applied to the DGS‎-1210‎-28P PoE switch so that unnecessary power consumption can be saved during off hours‎.‎ The switches can also detect the length of connected cables to automatically reduce power usage on shorter cable connections‎.‎Easy ManagementThis D‎-Link Web Smart Switch is designed for easy management‎.‎ All configurations can be made through a Web interface regardless of the host PC‎'‎s operating system‎.‎ Furthermore‎,‎ the web UI contains ten language options to make operations more straightforward‎.‎ In the initial installation‎,‎ the Smart Console Utility will automatically discover all D‎-Link Smart switches in the network‎,‎ allowing administrators to assign IP addresses and subnet masks quickly‎.‎ It also allows simultaneous firmware upgrades to multiple switches‎,‎ saving a great deal of time‎.‎ Important management commands‎,‎ such as download firmware or configuration file‎,‎ can be completed using batch operations for multiple switches‎.‎Auto Surveillance VLAN and Voice VLANThis D‎-link Web Smart Switch automates the process of setting up IP surveillance and VoIP devices on a network‎.‎ Auto Surveillance VLAN consolidates data and surveillance video transmission through the network‎,‎ sparing businesses the expense of maintaining dedicated facilities‎.‎ ASV also protects the quality of realtime video by grouping IP surveillance devices on a single high priority VLAN‎.‎ This ensures that surveillance video streams will not be affected when ordinary data traffic is at a high level‎.‎ Similarly‎,‎ the Auto Voice VLAN guarantees clear quality and efficient transmission for all voice communication‎.‎Extensive Layer 2 FeaturesEquipped 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 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 administrators and customer service representatives‎,‎ can rapidly discover the type of error and determine the cable quality‎.‎Secure Your NetworkD‎-Link‎'‎s innovative Safeguard Engine protects the switches against traffic flooding caused by virus attacks‎.‎ This switch also supports 802.1X port‎-based authentication‎,‎ allowing the network clients to be authenticated through external RADIUS servers‎.‎ In addition‎,‎ the Access Control List ‎(‎ACL‎)‎ feature enhances network security and protects the network by screening traffic from illegal MAC or IP addresses‎.‎ ARP Spoofing Prevention prevents malicious intruders from sending massive fake ARP messages through a manipulated source‎.‎ This protects important data from being stolen by Man‎-in‎-the‎-Middle attacks‎,‎ and prevents wasting CPU cycles on these packets‎.‎ For added security‎,‎ the DHCP Server Screening feature blocks rogue DHCP server packets from user ports to prevent unauthorized IP assignment‎.‎
