Silver 1U rack-mount switch with 48 RJ45 ports and four SFP slots

TP-Link

TP-Link TL-SG3452P 48-port Gigabit L2+ managed PoE network switch

SKU CH-7CKR-TG1BW

A 48-port Gigabit L2+ managed PoE+ switch with four SFP slots, 384 W budget and Omada SDN integration

  • Switch Type1
  • 48 PoE+ ports deliver up to 30W each for powering IP cameras and access points
  • 384W total PoE budget supports dense deployments without extra injectors
  • 4 SFP slots enable Gigabit fibre uplinks for backbone connectivity
  • Omada SDN integration provides centralised cloud management across multiple sites
  • L2+ static routing moves traffic between VLANs efficiently without a separate router

48-Port Gigabit PoE+ Switch

The TP-Link TL-SG3452P delivers 48 PoE+ RJ45 ports compliant with 802.3 at/af standards, each supplying up to 30W within a total 384W budget. Four Gigabit SFP slots add fiber uplink flexibility. The L2+ managed feature set targets businesses deploying IP cameras, VoIP phones or wireless access points across a single rack-mountable unit.

Thermals Noise and Power

The chassis measures 17.32 x 12.99 x 1.73 inches and weighs 12.65 lbs, fitting a standard 1U rack space. Internal cooling handles the 384W PoE load plus switching overhead without external power bricks. Fan speed scales with temperature, so acoustic output remains proportional to actual port utilisation rather than running at a fixed high rate.

Build Integration Requirements

The switch integrates with the Omada SDN platform for centralised cloud management via hardware controller, software controller or the Omada app. Static routing and 802.1Q VLAN support simplify Layer 3 segmentation. IPv6 readiness and security features such as ACL, DHCP Snooping and 802.1X authentication protect traffic. PoE Auto Recovery reboots unresponsive powered devices automatically, reducing on-site maintenance. Builders needing more than 48 powered ports or a higher per-port wattage ceiling should plan for additional switches.

Questions about this item

How do I mount the TL-SG3452P in a rack and what clearance mistake should I avoid?

The unit measures 17.32 x 12.99 x 1.73 inches and weighs 12.65 lbs; allow enough rear space for the 384 W power supply airflow so heat does not recirculate.

Which components will need attention or replacement after extended use?

The internal fans and the 384 W power supply are the primary wear items; dust buildup on fan intakes reduces cooling for the 48 PoE+ ports.

What limit appears first when all 48 PoE+ ports run near 30 W continuously?

The 384 W total PoE budget caps combined draw, so sustained full-power use on every port will hit the budget before per-port limits.
