Ubiquiti ECS-48S-PoE Enterprise Campus 48-Port 2.5G/10G PoE+++ Stackable Layer 3 Switch

48-Port Campus Access with High-Power PoE

The Ubiquiti ECS-48S-PoE is a managed Layer 3 campus switch with thirty-two 2.5GbE and sixteen 10GbE PoE+++ access ports. It combines 48 powered connections, four 25G uplinks and dedicated 100G stacking interfaces, with up to 2,150 W of PoE in shared mode at 200–240 V AC.

Highlights

Powered Multi-Gigabit Access

• 32 × 2.5GbE and 16 × 10GbE access ports.
• Up to 90 W PoE+++ per port, within the total power budget.

Uplinks and Stacking Hardware

• Four SFP28 uplinks supporting 25G, 10G and 1G.
• Two rear 100G QSFP28 stacking ports.

Serviceable Campus Hardware

• Two hot-swappable 1,200 W power modules and four replaceable fan modules.
• Etherlighting, out-of-band management Ethernet and serial console.

Key Features

A Port Mix for Larger Access Networks

Thirty-two 2.5GbE ports support a larger group of powered endpoints, while sixteen 10GbE ports serve higher-bandwidth devices. Allocate ports around the access points, workstations and other equipment being installed. This port mix differs from the non-stacking ECS-48-PoE, so the two models should be assessed individually.

Size the PoE Budget for the Power Mode

Each access port supports up to 90 W at the switch, subject to the total available budget. With the supplied pair of 1,200 W modules, 200–240 V AC provides 2,150 W in shared mode or 950 W in redundant mode. Lower input voltage reduces these figures. Reserve sufficient PoE capacity for the intended failover mode; the per-port maximum cannot be supplied to all ports simultaneously at full load.

25G Uplinks and Stacking Interfaces

Four SFP28 uplinks support 25G, 10G and 1G connections to compatible aggregation equipment. The two rear QSFP28 interfaces are dedicated 100G stacking ports, rather than general-purpose uplinks. Stacking and cross-stack LAG are listed in the technical specifications, but Ubiquiti currently marks stacking as coming soon on its enterprise overview. Confirm availability in the intended firmware and UniFi Network release before relying on these functions.

Layer 3 Services and Access Controls

Inter-VLAN routing, static routing, a local DHCP server and DHCP relay support campus network segmentation. 802.1X, DHCP snooping and ACLs help control network access. QoS, multicast controls and Pro AV profiles support environments carrying voice, video and business traffic.

Serviceable Hardware and Clear Port Identification

Hot-swappable power and fan modules simplify servicing within the rack. Etherlighting helps identify port location, link speed and native network assignments. A local touchscreen, dedicated management Ethernet interface and serial console provide additional access for setup and troubleshooting.

UniFi and Rack Requirements

UniFi Network version 10.6.101 or later is required. Suitable uplinks can connect to the Enterprise Campus Aggregation switch. Verify the required optics or DACs and purchase them separately. The full-depth 1U chassis requires a four-post rack, or suitable centre support or a cantilever shelf for a two-post installation.

Summary

The ECS-48S-PoE combines powered multi-gigabit access, 25G uplinks and serviceable rackmount hardware for campus networks. Choose the PSU operating mode around the endpoint load and redundancy requirement, and confirm stacking software availability before designing a topology that depends on it.
