TP-Link TL-SG3452XP JetStream 48-Port Gigabit L2+ Managed PoE+ Switch - 4x 10GE SFP+, 500W PoE Budget
The TP-Link TL-SG3452XP is a 48-port rack-mount L2+ managed switch with PoE+ on every copper port and four 10-Gigabit SFP+ uplinks. It is built for larger sites — a floor of access points, a camera estate, a building full of VoIP handsets — where the switch has to both power the edge and carry its traffic back over 10G fibre.
Why this product
PoE+ on all 48 Gigabit ports
Every copper port supplies up to 30 W under 802.3af and 802.3at, with a 500 W budget shared across the switch. Perpetual PoE keeps powered devices alive through a reboot and fast PoE brings them back before the switch has finished starting.
Four 10GE SFP+ uplinks
Four SFP+ slots run at 1 or 10 Gbps, so the switch can be fed by 10-Gigabit fibre to the core rather than bottlenecked on a Gigabit uplink. Modules and DAC cables are sold separately.
176 Gbps switching capacity
A 176 Gbps switching fabric and a 130.94 Mpps forwarding rate, with a 12 Mbit packet buffer and 9 KB jumbo frame support.
L2+ with static routing
Forty-eight IPv4/IPv6 static routes across up to 128 IP interfaces, plus a DHCP server and relay, handle inter-VLAN routing without a separate Layer 3 device.
Ring protection with ERPS
ERPS v1 and v2 with up to 255 rings sit alongside the usual STP, RSTP and MSTP, for ring topologies that need sub-second recovery.
Omada SDN capable
Runs standalone from its own web UI and CLI, or joins an Omada network managed centrally from an OC200 or OC300 hardware controller, the software controller, or the cloud-based controller.

- Powers 802.3af and 802.3at devices — Wi-Fi access points, IP cameras, VoIP phones and door controllers — at up to 30 W per port, using Alternative A pinout.
- The four SFP+ slots accept 1 Gbps or 10 Gbps transceivers and DAC cables for uplinks to a core switch or between buildings.
- Managed from a browser over HTTPS, or by CLI over the RJ45 console port, the Micro-USB console port, Telnet or SSH. SNMP v1/v2c/v3 and RMON are supported, with dual image and dual configuration.
- Fits a standard 19-inch rack. A rackmount kit, screws, power cord, console cable and rubber feet are in the box.
- SFP+ modules, DAC cables and media converters are sold separately.
- TP-Link states that only one SM5310-T 10G RJ45 SFP+ module can be inserted at a time.
- TP-Link states the 500 W PoE budget is not guaranteed and will vary with the devices connected and the environment.
- Zero-Touch Provisioning requires the Omada Cloud-Based Controller specifically.
- TP-Link states that the ISP features — sFlow, QinQ, L2PT, PPPoE ID insertion and IGMP authentication — work in standalone mode only, not under controller management.
Best for
- Larger offices, schools and campuses powering a full floor of access points and cameras from one rack unit.
- Sites with a 10-Gigabit core, where the four SFP+ uplinks stop the access layer becoming the bottleneck.
- Networks already running Omada access points or gateways, which can bring the switch under the same controller.
- Ring topologies needing ERPS recovery alongside conventional spanning tree.
- Installations that want light inter-VLAN routing at the access layer rather than a separate Layer 3 switch.
Trade-offs
- High-power PoE devices: the ports are rated to 30 W each under 802.3af and 802.3at. PTZ cameras with heaters and some large displays expect the higher 802.3bt power classes.
- Powering 48 devices at full draw: 500 W across 48 ports averages about 10 W each. A full estate of 30 W devices will exceed the budget.
- Quiet rooms: three fans, rated by TP-Link at up to 48.2 dBA at one metre under full load at 45 °C. This belongs in a comms cabinet.
- Anyone wanting plug-and-play: this is a managed switch and it needs configuring.
- Buyers who need transceivers in the box: SFP+ modules and DAC cables are a separate purchase.
The TL-SG3452XP is TP-Link's 48-port L2+ managed PoE+ switch: every copper port carries power, four SFP+ slots carry 10-Gigabit uplinks, and a 500 W budget is shared across the estate.
All 48 Gigabit ports supply up to 30 W under 802.3af and 802.3at, using Alternative A pinout, which covers the great majority of access points, IP cameras, VoIP handsets and door controllers. Perpetual PoE keeps powered devices running through a switch reboot, and fast PoE brings them back up before the switch has finished starting. The 500 W budget averages roughly 10 W per port across a full chassis, so a mixed estate of low- and high-draw devices is the realistic load rather than 48 devices at maximum.
The four SFP+ slots run at 1 or 10 Gbps. On a site with a 10-Gigabit core that keeps the access layer from becoming the bottleneck, which matters once 48 ports of traffic are aggregating into one uplink.
Management is a full L2+ set: up to 4K VLAN groups with 802.1Q, QinQ and voice VLAN, STP, RSTP and MSTP plus ERPS v1 and v2 across as many as 255 rings, LACP aggregation, 802.1X with RADIUS authentication and accounting, time-based ACLs, eight QoS queues and IGMP for up to 1,000 groups. Forty-eight static routes across 128 IP interfaces, with a DHCP server and relay, cover inter-VLAN routing without a separate Layer 3 switch.
It runs standalone from its own web interface or CLI, or joins an Omada SDN network managed centrally alongside TP-Link access points and gateways. Three fans stay off below a 60 W PoE load at 25 °C; under a full load TP-Link rates it at up to 48.2 dBA at one metre. SFP+ modules and DAC cables are sold separately.
