Which switch delivers more PoE power, and at what standard?

The ES-48-500W provides a 500W shared PoE budget rated to the 802.3at (PoE+) standard, with a per-port ceiling of 34.2W. That budget is sufficient for most 802.3at cameras and single-radio access points, but a fully loaded chassis—48 ports each drawing 34.2W—would require 1,641W, so budget allocation planning is mandatory. The internal power supply is rated at 150W DC, with total system power (including PoE) reaching 500W.

The USW-PRO-MAX-48-POE raises the ceiling on both dimensions. Its PoE budget is 720W simultaneous, and the standard is 802.3bt (PoE++), which allows up to 90W per port. The internal AC supply is rated at 870W (100–240V AC, 50/60 Hz), reflecting the higher headroom. The 220W delta in total budget translates directly to the ability to power more power-hungry endpoints—dual-radio Wi-Fi 6E APs, PTZ cameras with heaters, or 802.3bt-class devices—without external injectors or midspan hardware. The ES-48-500W does not support the 802.3bt standard; devices requiring more than 30W per port cannot be powered from it natively.

How do switching capacity, forwarding rate, and port-speed options compare?

The ES-48-500W specifies a switching capacity of 140 Gbps (per marketing spec tile) alongside a separate listing of 20 Gbps (per the structured spec field) and a non-blocking throughput figure of 70 Gbps with a forwarding rate of 104.16 Mpps in the datasheet section, but also lists 14.88 Mpps in the structured spec field. These figures are inconsistent across the provided data; buyers should confirm against the official Ubiquiti datasheet. Uplinks consist of 2× 10G SFP+ and 2× 1G SFP ports. All 48 RJ45 access ports run at 1G.

The USW-PRO-MAX-48-POE lists 224 Gbps switching capacity with 112 Gbps non-blocking throughput and a forwarding rate of 167 Mpps—both figures are internally consistent and higher than either ES-48-500W number. Port-speed mix is also broader: the 48-port RJ45 bank includes both 1G and 2.5G capability, and uplinks are 2× 10G SFP+. The 2.5G access ports are a meaningful differentiator for Wi-Fi 6/6E APs that exceed gigabit throughput. The ES-48-500W does not list 2.5G access-port support in the provided specifications.

What management capabilities and compliance certifications does each switch carry?

The ES-48-500W is explicitly spec'd as Layer 2/3 Managed with Web GUI, CLI, SNMP, and an RJ45 serial console port—four distinct management access paths. Layer 3 capability indicates support for inter-VLAN routing and static routing functions at the switch level, which is relevant for distributed camera networks that need to route traffic locally rather than hairpin through a core router. Certifications listed are CE, FCC, and IC.

The USW-PRO-MAX-48-POE lists management as 'Ethernet' in the structured spec field, which does not specify Layer 2 vs. Layer 3 capability, CLI access, SNMP support, or a serial console; these details are absent from the provided specifications. However, it adds VLAN support of up to 1,000 VLANs—a figure not specified for the ES-48-500W—and carries NDAA compliance certification, which is a procurement requirement for U.S. federal, state, and many enterprise contracts. Its certification list includes CE, FCC, IC, and Anatel (Brazil). The NDAA designation is absent from the ES-48-500W specifications.

Which should you choose: the ES-48-500W or the USW-PRO-MAX-48-POE?

Our take: The USW-PRO-MAX-48-POE is the stronger choice when the deployment requires higher per-port power, 802.3bt devices, broader multi-speed access ports, or NDAA-compliant hardware. Its 720W PoE++ budget exceeds the ES-48-500W's 500W PoE+ budget by 220W, its switching capacity of 224 Gbps versus 140 Gbps (or 70 Gbps non-blocking per the ES-48-500W datasheet) is materially higher, and its forwarding rate of 167 Mpps versus 104.16 Mpps gives it more headroom under sustained mixed traffic. The 2.5G access-port option on the USW-PRO-MAX-48-POE directly addresses Wi-Fi 6/6E backhaul needs. The ES-48-500W remains a valid option for pure 802.3at PoE+ environments where Layer 3 switching, CLI/SNMP access, and a confirmed serial console port are operationally important—features explicitly spec'd on the ES-48-500W but not confirmed in the USW-PRO-MAX-48-POE data provided. NDAA-governed bids must use the USW-PRO-MAX-48-POE.
