D-Link 28-Port Fast Switch (DES-1210-28P)

The D-Link DES-1210 Series is the latest generation of Web Smart switches to feature D-Link Green technology.  These switches integrate advanced management and security functions that provide performance and scalability.  The DES-1210-28P is equipped with 24 10/100Mbps PoE ports, 2 10/100/1000BASE-T ports, and 2 combo 10/100/1000BASE-T/SFP ports. 

PoE Support

One model in the DES-1210 series family, the DES-1210-28P, delivers Power-over-Ethernet capabilities, simplifying deployments with IP cameras, VoIP phones, wireless access points, and other powered devices. It supports 802.3at on its first four ports (30W max per port) and supports 802.3af on ports 5 through 24 (15.4W max. per port.) Its total power budget is 193W. Using the product’s 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. The switches also support time-based PoE – an option that allows administrators to set a time window that determines when each port’s PoE power is turned on and off.

Energy Saving

The DES-1210 Series Switches are 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 PoE switches 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 Management

The D-Link Web Smart Switch series is designed for easy management. All configuration 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 D-Link Network Assistant 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 VLAN

The D-Link Web Smart series 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 helps protect the quality of real time video by grouping IP surveillance devices on a single high priority VLAN. This helps ensure that surveillance video streams will not be affected when ordinary data traffic is at a high level. Similarly, the Auto Voice VLAN helps provide clear quality and efficient transmission for all voice communication.

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 administrators and customer service representatives, can rapidly discover the type of error and determine the cable quality.

Network Security Features

D-Link’s innovative Safeguard Engine® helps to protect the switches against traffic flooding caused by virus attacks. The switches also support 802.1X port-based authentication, allowing the network clients to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature helps enhance network security and helps protect the network by screening traffic from illegal MAC or IP addresses. ARP Spoofing Prevention helps to prevent malicious intruders from sending massive fake ARP messages through a manipulated source. This helps to protect important data from being stolen by Man-in-the-Middle attacks, and helps prevent wasting CPU cycles on these packets. For added security, the DHCP Server Screening feature helps to block rogue DHCP server packets from user ports to help prevent unauthorized IP assignment.
