D-link DGS-1210-28P 28-Port Gigabit PoE Switch 

The D-Link DGS-1210-28P is a 28-port Gigabit PoE (Power over Ethernet) switch designed for small and medium-sized businesses that require a reliable and efficient network infrastructure.

Key features and functionalities:

1. Port Configuration: The switch offers 24 10/100/1000 Mbps Gigabit Ethernet ports, which allow for high-speed data transfers and seamless connectivity between devices. Additionally, it includes four Gigabit SFP (Small Form-factor Pluggable) ports, providing flexibility for fiber optic or uplink connections.

2. Power over Ethernet (PoE): The switch supports PoE, enabling power and data transmission over a single Ethernet cable. This feature eliminates the need for additional power outlets and simplifies the deployment of PoE-enabled devices such as IP cameras, wireless access points, and VoIP phones.

3. PoE Budget: The DGS-1210-28P offers a generous PoE power budget, providing up to 193W of total power. This allows for simultaneous PoE connections to multiple devices without the need for an external power source.

4. PoE Management: The switch incorporates advanced PoE management features, including power budgeting, scheduling, and priority settings. These functionalities allow administrators to optimize power allocation, ensure device availability, and prioritize critical equipment in case of power limitations.

5. VLAN Support: The switch supports Virtual Local Area Networks (VLANs), which enable network segmentation and improve security and performance. Administrators can create multiple VLANs to isolate traffic, control access, and enhance overall network efficiency.

6. Quality of Service (QoS): The DGS-1210-28P prioritizes network traffic using QoS features such as 802.1p Priority Queues and DSCP (Differentiated Services Code Point) settings. This ensures that time-sensitive applications like VoIP or video streaming receive the necessary bandwidth and low latency for optimal performance.

7. Security Features: The switch includes a range of security measures to safeguard the network, such as Access Control Lists (ACLs), DHCP Snooping, IP-MAC-Port Binding, and Port Security. These features help protect against unauthorized access, prevent IP spoofing, and enhance overall network integrity.

8. Management Options: The DGS-1210-28P offers various management options to suit different preferences and requirements. It supports web-based management through an intuitive user interface, as well as SNMP (Simple Network Management Protocol) for centralized network monitoring and control.

9. Energy Efficiency: The switch is designed to be energy-efficient, featuring D-Link Green technology. It includes features such as IEEE 802.3az Energy Efficient Ethernet and Smart Fan control, which dynamically adjust power consumption based on network traffic and environmental conditions, resulting in energy savings.

10. Easy Installation: The switch is designed for easy deployment and installation. It includes a rack-mountable form factor, allowing for convenient placement in server rooms or network cabinets. It also supports plug-and-play functionality, making it straightforward to set up and integrate into existing network environments.

Overall, the D-Link DGS-1210-28P is a feature-rich Gigabit PoE switch that provides reliable connectivity, efficient power distribution, and robust management capabilities, making it suitable for small to medium-sized businesses looking to enhance their network infrastructure.
