TP-Link TL-SG3452 JetStream 48-Port Gigabit L2 Managed Switch with 4 SFP Slots
Designed for evolving networks that demand reliability, speed, and intelligent traffic management, the TP-Link TL-SG3452 JetStream 48-Port Gigabit L2 Managed Switch with 4 SFP Slots is a robust cornerstone for small to medium-sized businesses, classrooms, and retail environments. This switch combines a dense port density with flexible uplinks, letting you extend your Ethernet backbone without compromising performance or security. Its JetStream firmware delivers enterprise-grade features in a compact, energy-efficient package, making it easier than ever to deploy sophisticated network configurations—whether you’re segmenting departments, isolating guest traffic, or aggregating uplinks for high-bandwidth applications. With 48 copper ports, you can connect desktops, printers, IP phones, cameras, and access points, while the four gigabit SFP slots give you fiber or high-speed copper options for uplinks to core switches, servers, or metro networks. The TL-SG3452 is built to support scalable networks today and adapt to your needs tomorrow, featuring L2 and L2+ capabilities, VLAN segmentation, QoS prioritization, and robust security features that help you protect sensitive data and maintain quality of service across the organization. From simplified management to resilient design, this switch is engineered to reduce downtime, streamline administration, and maximize network performance as your endpoints and services grow.
- 48 x 10/100/1000 Mbps RJ45 ports plus 4 x 1 Gbps SFP slots provide dense access with flexible uplinks, enabling you to run conventional Ethernet connections alongside high-speed fiber links for aggregation or remote sites.
- Layer 2 and Layer 2+ features enable sophisticated traffic control, including VLAN tagging with 802.1Q, private VLANs, and enhanced multicast support for IP video streams without congesting the network.
- Enterprise-grade QoS with traffic prioritization, bandwidth management, and multiple queuing disciplines ensures critical applications—such as VoIP, video conferencing, and real-time data transfers—receive consistent performance even during peak traffic.
- Comprehensive security toolkit — IP-MAC binding, DHCP snooping, storm control, and per-port security policies — protects endpoints from spoofing, spoofed DHCP servers, and network abuse while simplifying policy enforcement across departments.
- Easy management and reliable operation through a web-based GUI, CLI access, SNMP support, and robust monitoring features; lifecycle management is simplified with efficient firmware updates and configuration backups, reducing downtime during deployments.
Technical Details of TL-SG3452
- Ports: 48 x 10/100/1000 Mbps RJ45 ports; 4 x 1 Gbps SFP slots for flexible uplinks and fiber connections
- PoE: Non-PoE model (no power-over-Ethernet on this variant; for PoE, consider a PoE-capable JetStream model)
- Layer support: Layer 2 switching with Layer 2+ features, including static routing options for simple inter-VLAN routing scenarios
- VLAN: Supports 802.1Q VLAN tagging with multiple VLANs and VLAN-based security and traffic separation
- QoS: Hierarchical QoS with port-based and VLAN-based prioritization to ensure critical applications receive bandwidth priority
- Security: IP-MAC binding, DHCP snooping, IP source guard, port security, ARP protection, and ACLs for granular traffic filtering
- Multicast: IGMP Snooping and MLD Snooping to optimize multicast traffic and reduce unnecessary broadcast congestion
- Spanning Tree: STP/RSTP/MSTP support to prevent switching loops and provide redundancy in larger network topologies
- Link Aggregation: LACP support for combining multiple ports into a single logical link for increased bandwidth and resilience
- Management: Web-based graphical user interface (GUI), Secure Shell (SSH), Telnet, SNMP, and LLDP for topology discovery and remote management
- Performance: Optimized switching fabric and robust hardware design aimed at stable operation under typical enterprise workloads
- Form factor and reliability: 1U rack-mountable chassis with proper ventilation to sustain long, uninterrupted operation in network closets
how to install TL-SG3452
- Unbox the switch and verify all components, then place the unit in a suitable rack or a secure, ventilated workspace
- Connect the power cord and ensure the device powers on correctly; check status LEDs for normal operation
- Connect endpoints (PCs, printers, IP phones, etc.) to the 48 copper ports and use the 4 SFP slots for uplinks to the core, server, or edge devices
- Access the management interface via the default IP address or through DHCP on your network; log in with the default credentials and configure a secure administrator account
- Set up VLANs, assign ports to appropriate VLANs, configure QoS rules for critical applications, enable security features (DHCP snooping, IP-MAC binding, ACLs), and establish link aggregation where needed
- Save the configuration and perform a basic health check by validating connectivity between devices across VLANs and confirming multicast groups are properly managed
Frequently asked questions
- What is the TL-SG3452 best for? It is ideal for small to mid-sized networks that require a high-density 48-port Gigabit switching solution with flexible SFP uplinks, solid Layer 2+ features, and centralized management.
- Does it support PoE? This specific model is non-PoE. If you need PoE capabilities, consider a PoE-enabled JetStream model such as TL-SG3452P.
- How can I manage the switch? You can manage it via a web GUI for ease of use, with CLI access (SSH/Telnet) for advanced configurations, and SNMP for monitoring and integration with network management systems.
- Can I aggregate links? Yes, the switch supports Link Aggregation (LACP) to increase bandwidth and provide redundant connections between switches or to servers.
- What security features are included? The switch includes IP-MAC binding, DHCP snooping, port security, ARP protection, and ACLs to control traffic and mitigate common threats.
