Description
Enterprise-Grade 24-Port PoE+ Management for CCTV, VoIP, and Business Networks
The TP-Link TL-SG3428MP is a JetStream 28-port Gigabit L2+ managed switch built for demanding commercial and enterprise network installations. With 24 IEEE 802.3at/af PoE+ ports and a generous 384W PoE budget, it can simultaneously power IP cameras, VoIP phones, wireless access points, and access control devices — all managed centrally via the Omada SDN platform or standalone web interface.
Key Features
-
24× Gigabit PoE+ Ports (802.3at/af) — up to 30W per port, 384W total PoE budget for powering IP cameras, APs, and VoIP phones
-
4× Gigabit SFP Uplink Slots — fibre or copper uplinks for high-speed backbone connectivity
-
56 Gbps Switching Capacity — non-blocking performance for high-density network environments
-
L2+ Features with Static Routing — inter-VLAN routing without a dedicated router for simplified network design
-
Omada SDN Integration — Zero-Touch Provisioning, centralised cloud management, and intelligent monitoring
-
Robust Security — IP-MAC-Port Binding, ACL, Port Security, DoS defence, DHCP Snooping, 802.1X, RADIUS authentication
-
L2/L3/L4 QoS — 8 priority queues with 802.1p CoS/DSCP for voice and video traffic prioritisation
-
IGMP Snooping — optimises multicast traffic for IP camera and IPTV deployments
-
Link Aggregation (LACP 802.3ad) — up to 8 aggregation groups for increased uplink bandwidth and redundancy
-
Rack-Mountable, Dual Fan — 1U rack design with active cooling for 24/7 operation
- 5-Year Warranty
Typical Use Cases
- Centralised PoE switching for large IP CCTV installations (16–24 cameras)
- Enterprise Wi-Fi deployments powering multiple Omada or third-party access points
- VoIP phone systems in commercial offices and call centres
- Access control and intercom systems requiring PoE and VLAN segmentation
- Multi-VLAN network segmentation for guest, staff, IoT, and security traffic
- Aggregation switch in multi-floor or multi-building network topologies

Frequently Asked Questions
- How many IP cameras can the TL-SG3428MP power simultaneously?
- With a 384W PoE budget and 24 PoE+ ports, it can power up to 24 cameras. Actual capacity depends on each camera's power draw — for example, 24 cameras at 15W each would use 360W, comfortably within budget. High-power PTZ cameras drawing 25–30W will reduce the total count accordingly.
- Does this switch require an Omada controller?
- No. The TL-SG3428MP can be managed as a standalone switch via its web interface, CLI, or SNMP. An Omada controller (software, cloud, or hardware) is optional and enables centralised multi-device management across sites.
- What is static routing and why is it useful?
- Static routing (L2+) allows the switch to route traffic between VLANs without a dedicated router. This simplifies network design in installations where you need to segment traffic — for example, separating CCTV, staff, and guest networks — while keeping inter-VLAN communication possible.
- Can I use fibre uplinks with this switch?
- Yes. The 4× Gigabit SFP slots support both fibre (via SFP transceivers) and copper (via SFP-to-RJ45 modules) uplinks, making it suitable for long-distance backbone connections between floors or buildings.
- Is the TL-SG3428MP suitable for 24/7 operation?
- Yes. It features a rack-mountable 1U chassis with dual active cooling fans, designed for continuous operation in network cabinets and server rooms.
