D-Link DGS-1250-28XMP
A 28-port 10-Gigabit smart managed PoE switch that delivers a cost-efficient enterprise access and Small-to-Medium Business (SMB) access/aggregation solution. It offers 24x 10/100/1000BASE-T PoE ports, which transmit both data and power over Ethernet cable to facilitate device installation. It also comes with 4x 10G SFP+ ports for optical connections using multimode or single-mode SFP transceivers. Other features include a Console Port with full Command Line Interface (CLI), 11 Web languages, QoS enablement, and Advanced Layer-2 w/Lite Layer-3 features, making it a real network horsepower at a great value.
- 24 x 10/100/1000BASE-T PoE ports
- 4 x 10G SFP+ ports for choosing the most suitable media type for your requirement
- Lite L3 Static Routing for increased network efficiency
- Advanced security features such as Access Control List, IMPB, and 802.1X Authentication to enhance network security and protect the internet IT network
- 370W PoE Power Budget (802.3af/at) to allow more power for connected devices
- Dual Image & Configuration for reduced downtime
- Supports STP/RSTP/MSTP to maintain the quality of network
- Full CLI for easy management
- QoS Enablement for performance improvement of critical network traffic
- 11 Web Languages for management flexibility
Easy Maintenance, Less Downtime
The DGS-1250 Series supports Dual Image and Dual Configuration functionality, as well as a Console Port, all of which make it easier to configure, troubleshoot, and make other changes without interfering with network operation, while full Command Line Interface (CLI) functionality enables remote configuration, without the need for the Internet. And if a network issue ever does occur, the supported Spanning Tree Protocols (STP/RSTP/MSTP) help keep things running without interruptions or downtime.
Automatic Configuration
The DGS-1250 Series supports Auto Voice VLAN and Surveillance Mode, which allow Voice and Video traffic to be automatically identified and handled differently from 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.
High PoE Budget (370W)
The DGS-1250 series offers Power-over-Ethernet (PoE), which simplifies deployment with IP cameras, VoIP phones, Wireless Access Points, and other powered devices. Using the switch’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. All PoE models support the IEEE 802.3af and 802.3at standards, and each PoE power budget varies per model.
Extensive Management and Advanced Features
The DGS-1250 Series comes with 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. The series also supports advanced features such as Static Routing, which allows for communication between different user groups in different VLAN segments in a network.
Management Versatility
The DGS-1250 Series comes with the D-Link Network Assistant (DNA) utility so admins can remotely control their network to the port level. DNA allows customers to easily discover multiple D-Link Smart Managed Switches within the same L2 network segment and display them onscreen for instant access.
