Ubiquiti ECS-48S-POE – Enterprise Campus 48S 48-Port PoE+++ Layer 3 Switch
Overview
The Ubiquiti ECS-48S-POE is a 1U full-depth UniFi Enterprise Campus Layer 3 switch designed for high-density access and aggregation deployments. It provides 48 PoE+++ Ethernet ports across 32 multi-gigabit 2.5GbE ports and 16 multi-gigabit 10GbE ports, together with 25G SFP28 and 100G QSFP28 uplink interfaces.
The switch supports Layer 3 networking, switch stacking, Etherlighting™, redundant hot-swappable power supplies, and hot-swappable fan modules. Its high-capacity PoE architecture supports up to 90W per PoE+++ port for compatible powered devices.
Technical Information
The ECS-48S-POE provides 680Gbps switching capacity, 340Gbps total non-blocking throughput, and a 506Mpps forwarding rate. The switching platform supports up to 1,000 VLANs, a 32,000-entry MAC address table, 512 IPv4 static routes, and an 8MB packet buffer.
All 48 RJ45 ports support PoE+++ with negotiated power levels up to 90W per port. The switch uses two hot-swappable 1,200W AC/DC power modules and four hot-swappable fan modules. Total PoE availability is dependent on input voltage and power configuration, with up to 2,150W available in 200–240V shared mode.
Compatibility
The ECS-48S-POE is managed through UniFi Network and requires UniFi Network version 10.6.101 or later according to Ubiquiti's current technical specifications. Its Ethernet ports support multiple link speeds, while the SFP28 and QSFP28 interfaces provide higher-speed fiber or direct-attach connectivity when compatible transceivers or cables are used.
For rack installation, Ubiquiti specifies a 19-inch four-post rack with post depths from 650 to 1,000mm. Ubiquiti also notes that a 4-post rack, or appropriate center-mount bracket or cantilever shelf support, should be used for two-post rack installations.
Key Features
- 32 × 2.5GbE RJ45 and 16 × 10GbE RJ45 PoE+++ ports
- 4 × 25G SFP28 and 2 × 100G QSFP28 interfaces
- 680Gbps switching capacity and 340Gbps non-blocking throughput
- Two hot-swappable 1,200W power modules with redundant operation
- Four hot-swappable fan modules and UniFi switch stacking support
Applications
The ECS-48S-POE is suited to enterprise campus access, high-density PoE deployments, WiFi 7 access-point infrastructure, surveillance networks, AV systems, and other environments requiring multi-gigabit access with high-capacity uplinks.
Its 10GbE PoE+++ ports can provide high-bandwidth wired connectivity and up to 90W of power to compatible devices, while the 25G SFP28 and 100G QSFP28 interfaces support high-speed network uplinks and inter-switch connectivity.
DC Supplies Product Note
When sizing the ECS-48S-POE, distinguish between the switch's 250W maximum consumption excluding PoE output and its maximum 2,400W consumption including PoE output. Available PoE capacity also changes according to AC input voltage and whether the two power modules operate in shared or redundant mode.
