Overview
Overview
The Ubiquiti UniFi Enterprise Campus 48S PoE is the stacking-capable member of the ECS switch family — a 1U rack-mount Layer 3 managed switch that combines high-density PoE+++ delivery with built-in 100G QSFP28 uplinks and switch stacking for scalable, high-availability campus distribution. All 48 data ports support PoE+++ (up to 90W per port), providing enough power for Wi-Fi 7 access points, IP cameras, VoIP, and PoE++ devices across large deployments.
The port layout includes 32 × 2.5 GbE RJ45, 16 × 10 GbE RJ45, 4 × 25G SFP28, and 2 × 100G QSFP28 — delivering 680 Gbps switching capacity with 340 Gbps non-blocking throughput. Switch stacking allows multiple ECS-48S-POE units to be managed as a single logical switch, simplifying large deployments. Dual hot-swappable 1,200W PSUs, four hot-swappable fans, a 1 GbE OOB management port, and a serial console port round out the enterprise feature set. NDAA compliant, CE/FCC/IC certified.

Software
Managed by UniFi Network
The ECS-48S-POE is fully managed through the UniFi Network application — the same centralised platform used across the entire UniFi ecosystem. Configure VLANs, PoE schedules, port profiles, inter-VLAN routing, stacking topology, and Layer 3 features from a single interface with no per-device licensing fees. The OOB management port allows secure out-of-band access to the switch even when the main network is unavailable.
Core management capabilities
- Switch stacking management — configure and manage multiple ECS-48S-POE units as a single logical switch from the UniFi dashboard.
- Port management — configure speed, PoE output, VLAN assignment, and port profiles per port.
- PoE scheduling — set time-based PoE on/off schedules per port to manage power consumption and device uptime.
- VLAN & routing — create and manage VLANs, inter-VLAN routing, and static routes directly in UniFi Network.
- Remote monitoring — real-time port statistics, power draw per port, and switch health via UniFi Cloud from anywhere.
- OOB management — dedicated 1 GbE management port provides out-of-band access independent of data plane connectivity.
- Firmware updates — push updates remotely without on-site access.
- Pro AV profiles — one-click network optimisation for Dante, NDI, Q-SYS, and other professional AV protocols.
Requirements
