1. Number of Ports:
   • 48 ports supporting Gigabit Ethernet with PoE/PoE+ capabilities. These ports can provide both data connectivity and power to PoE-enabled devices such as IP cameras, VoIP phones, or access points.
   • 4 combo ports that can be configured as either 1000BASE-T (RJ-45) or SFP interfaces, providing flexibility for various connectivity options.
2. Power over Ethernet (PoE/PoE+):
   • The PoE/PoE+ feature allows the switch to deliver power to connected devices over Ethernet cables. PoE+ supports higher power levels than standard PoE, making it suitable for a broader range of devices.
3. Combo Ports:
   • The 4 combo ports offer flexibility for connecting to other network devices using either copper (RJ-45) or fiber optic (SFP) connections. Users can choose the appropriate connectivity option based on their network requirements.
4. Manageable:
   • As a manageable switch, it comes with management features that allow users to configure and monitor the switch. This may include features such as VLAN support, Quality of Service (QoS), Link Aggregation, and security settings.
5. Deployment Scenarios:
   • This type of switch is suitable for deployment in environments where a large number of PoE-powered devices need to be connected, such as in IP surveillance systems, VoIP deployments, or Wi-Fi access point installations.
6. Smart Managed Switch:
   • D-Link refers to this series as « Smart Managed » switches, offering a level of management capabilities that provide flexibility and control over the network without the complexity of fully managed enterprise switches.
