The TP-Link TL-SG3452 is a Managed switch of the L2+ level, specifically designed for use in enterprise networks, campus infrastructures, and ISP environments. It features 48 Gigabit Ethernet ports (10/100/1000 Mbit/s) and 4 SFP slots for fibre connections, making it a powerful solution for networks with high port requirements. The device is designed as a 1U rackmount unit and offers a compact form factor with dimensions of 440 mm (width) × 220 mm (depth) × 44 mm (height). The device colour is black. It is fanless designed, enabling quiet operation and low maintenance requirements.

Applications

The TL-SG3452 is suitable for professional network infrastructures, particularly in enterprises requiring a scalable and centrally managed network environment. Integration into the Omada-SDN ecosystem enables central cloud management, allowing multiple sites to be monitored and configured via a single interface. Features such as Zero-Touch Provisioning (ZTP) simplify the setup of new devices without manual configuration. The network environment can thus be efficiently and securely managed, regardless of location.

Functions and Equipment in Detail

The switch offers extensive management functions, including web-based management, CLI control via the integrated console port (RJ-45/Micro-USB), as well as support for SNMPv1/v2c/v3 and SNTP. The Dual-Image function enables a secure firmware update strategy, where a backup software version is stored to quickly revert to a stable version in case of failure. System event logging and MIB support assist in network monitoring and diagnostics.

Technology Explained Simply

The switching capacity is 104 Gbit/s, ensuring high throughput for simultaneous data traffic across all ports. The transfer rate is 77.38 Mpps (millions of packets per second), highlighting efficiency in packet processing. The MAC address table includes 16,000 entries, sufficient to manage a large number of devices in the network. Support for Jumbo Frames up to 9000 bytes enables more efficient data transfer, especially for applications with high data throughput. The Store-and-Forward technology ensures that data packets are fully received and checked before forwarding, enhancing network security.

Compatibility and Accessories

The TL-SG3452 is equipped with 4 SFP slots, compatible with various SFP modules such as the TL-SM311LS (Singlemode LX) or TL-SM311LM (Multimode SX). These modules enable connections via fibre optic cables, extending the network’s reach and bandwidth. Additionally, Omada SM311LM Multi-Mode SFP modules (8-Pack) and Omada SM311LS (8-Pack) are available, suitable for larger networks. The Omada Nek SM331T is a copper transceiver also compatible with the switch.

Mounting and Installation

The switch is designed for mounting in a 19-inch rack and is delivered with a rack mounting kit. Installation is performed via the integrated power supply, designed for an input voltage of 100–240 V AC. The device features an integrated power supply, enabling operation without an external power unit. The operating temperature ranges from 0 to 40 °C, and the storage temperature from -40 to 70 °C. Relative humidity during operation is 10–90 %, and during storage 5–90 %.

Operational Advantages

The TL-SG3452 offers comprehensive security functions, including IP-MAC-Port binding, Access Control Lists (ACL), Port Security, DHCP Snooping, IGMP Snooping, BPDU filtering/protection, Loop Protection, and DoS-Defend. These functions protect the network from unauthorised access, ARP attacks, broadcast storms, and other threats. The Quality of Service (QoS) functions support L2- to L4-based prioritisation, enabling critical applications such as VoIP or video streaming to be prioritised. Support for VLANs (up to 4000) with features such as Port-based VLAN, Private VLAN, Protocol-based VLAN, Tagged VLAN, and Voice VLAN enables flexible network segmentation. Link Aggregation and Port Mirroring support network performance and diagnostics. Broadcast storm control and Spanning Tree Protocols (STP/RSTP/MSTP) prevent network failures caused by loops. The Static Route function supports routing within the network. IPv4 and IPv6 routes (48 each) enable IP address management in modern networks. Authentication is supported via MAC-based authentication, Port-based authentication, AAA, RADIUS, and TACACS+. SSH and SSL support enhances security during remote management.

Delivery Contents

The delivery includes the TL-SG3452 switch, an AC power cable, a rack mounting kit, rubber feet, and a quick start guide. These components enable direct installation and commissioning of the device without additional purchases.

Certification

The device is certified with CE, FCC, and RoHS, confirming compliance with European and American safety and environmental standards.
