Network switch D-Link S4200-28P-PL-SI-R2 L2 24xPoE+ 4xSFP 200W

Layer 2 network switch D-Link S4200-28P-PL-SI-R2 provides 24 PoE+ ports and four SFP uplink slots with a total PoE power budget of 200W. The switch supports basic L2 features including VLAN segmentation and standard switching functions, and is designed to deliver power and connectivity to IP phones, wireless access points and network cameras. With SFP uplinks it integrates fiber or gigabit uplinks to aggregation or core devices, making it suitable for small to medium office and branch deployments that require both data switching and device power over Ethernet.

Advantages

The D-Link S4200-28P-PL-SI-R2 combines 24 PoE+ ports with a 200W PoE budget to power multiple edge devices while maintaining basic Layer 2 switching features for network segmentation and traffic forwarding. Four SFP slots provide flexible uplink options for fiber or copper SFP modules, enabling scalable connections to distribution or core switches. Its feature set focuses on the essentials needed in small-to-medium networks: VLAN support, PoE management and reliable gigabit access ports in a single compact unit.

Suitable for

• Small to medium office LANs requiring powered endpoints (IP phones, Wi‑Fi access points)
• Branch office and retail locations with limited rack space and need for fiber uplinks
• Networked video surveillance installations where cameras require PoE power
• Edge switching where VLAN segmentation and basic L2 control are sufficient

Key specifications

• Ports: 24 x Gigabit Ethernet RJ‑45 with PoE+ support
• Uplink slots: 4 x SFP for fiber or SFP copper modules
• PoE budget: 200 W total for powering connected devices
• Switching: Layer 2 switching with VLAN support and standard MAC address learning
• Form factor: Rack-mountable compact switch suitable for closet or small rack installations
• Management: Basic L2 management features for port configuration and VLANs

How to use

Install the switch in a standard equipment rack or on a shelf in a network closet and connect the uplink SFP modules to your aggregation or core switch. Connect powered devices such as IP phones, Wi‑Fi access points and PoE cameras to the RJ‑45 ports; the switch will supply PoE+ power up to the configured budget. Configure VLANs and port settings through the switch’s management interface to segment traffic and set up uplink/trunk links. Monitor PoE consumption to ensure the total connected load stays within the 200W budget.

Usage recommendations

Distribute high‑power devices across different ports and monitor total PoE draw to avoid exceeding the 200W budget. Use appropriate SFP modules for the required fiber type and distance, and apply VLANs to separate voice, data and surveillance traffic for clearer network management.
