It’s important to note that the specific features and capabilities of the extension module may vary depending on the model and manufacturer.

• Port Configuration: The switch typically offers eight Gigabit Ethernet (GE) ports for high-speed connectivity, allowing you to connect various devices such as computers, printers, access points, IP cameras, and VoIP phones.
• PoE+ Support: This switch supports PoE+ (Power over Ethernet Plus), which means it can deliver more power to compatible PoE-enabled devices compared to standard PoE switches. The increased power capacity allows for the connection and powering of devices that require higher power, such as PTZ cameras or access points.
• PoE Ports: The switch typically includes eight PoE ports, which are capable of delivering both power and data over Ethernet cables. These ports eliminate the need for separate power adapters for PoE devices, simplifying installation and reducing cable clutter.
• Uplink Ports: In addition to the PoE ports, the switch usually has two Gigabit Ethernet uplink ports. These ports can be used to connect the switch to the network backbone or other switches to extend the network.
• Long Distance Support: The switch is mentioned to support up to 250 meters of Ethernet cable length for PoE devices. This extended distance capability allows for greater flexibility in deploying PoE devices in larger spaces or remote locations.
• Power Budget: The switch has a specified PoE power budget in watts. It determines the total amount of power available to be distributed among the connected PoE devices. The exact PoE power budget may vary depending on the specific model.
• Quality of Service (QoS): D-Link switches often offer QoS features to prioritize and optimize network traffic. This ensures that critical applications and data receive priority, resulting in improved performance and reduced latency.
• Management Options: The switch may provide different management options, such as a web-based interface, Command Line Interface (CLI), or dedicated management software. These tools allow you to configure and manage various settings of the switch, monitor performance, and control connected devices.
