48-Port PoE+ Managed Switch

The TP-Link TL-SG3452XP is a rackmount managed switch built for business networks that need both data and power over a single cable. It provides forty-eight gigabit RJ45 ports with PoE+ support plus four 10 Gbps SFP+ uplink slots for high-speed aggregation. The unit suits installers deploying IP cameras, wireless access points or VoIP phones across a single rack.

500 W PoE+ Power Budget

The switch delivers up to 30 W on each of its forty-eight PoE+ ports while staying within a total 500 W power budget. This figure decides how many high-draw devices can run simultaneously without an external injector. Ports comply with 802.3af and 802.3at standards so compatible endpoints negotiate power automatically.

Fan-Cooled 0-40 °C Operation

Active cooling keeps the chassis within its 0 to 40 °C operating range while powered from 100-240 V AC mains. The 1U rackmount form factor fits standard cabinets and the included rackmount kit secures the 17.30" x 13.00" x 1.70" enclosure. Acoustic output scales with thermal load during normal use.

Questions about this item

What does the 500 W PoE+ budget mean when I plug in 48 devices?

The switch can deliver up to 30 W per port across all 48 ports, but the total power drawn cannot exceed 500 W, so full 30 W is only available on a subset of ports at once.

How do the four 10 Gbps SFP+ uplinks limit real-world throughput?

Each SFP+ slot accepts 10 Gbps transceivers for fibre or copper uplinks, providing non-blocking 10 Gbps links to core switches or servers without sharing bandwidth with the 48 gigabit ports.

What physical space and mounting hardware does the unit need in a rack?

The switch measures 17.30" x 13.00" x 1.70" and includes a rackmount kit for standard 1U installation, plus rubber feet for desktop use.
