Ubiquiti UISP-S-PRO vs Ubiquiti USW-ENTERPRISE-24-POE: Specification Comparison
Both the Ubiquiti UISP-S-PRO and the USW-ENTERPRISE-24-POE are 24-port managed PoE switches in 1U rack-mount form factors, making them genuine cross-shop candidates for installers sizing out edge switching for IP camera, access control, or wireless AP deployments. The comparison turns on PoE standard and power budget, switching performance and port speeds, and management depth — three axes where the two models diverge meaningfully despite sharing the same port count and vendor.

Which switch delivers more PoE headroom and what PoE standard does each support?
The USW-ENTERPRISE-24-POE provides a documented 400W PoE budget across 24 ports rated at PoE+ (IEEE 802.3af/at), backed by an internal 550W universal AC/DC power supply (100–240V). This yields an average per-port budget of approximately 16.7W, sufficient to power 802.3at devices such as PTZ cameras, dual-radio APs, and door controllers without external injectors.
The UISP-S-PRO specifies PoE on all 24 ports at 802.3af only — the lower standard, capped at 15.4W per port at the PSE. No aggregate PoE power budget figure is provided in the available specifications for the UISP-S-PRO, so total budget cannot be directly compared. Installers powering 802.3at devices on the UISP-S-PRO cannot confirm compatibility from the provided specs and should verify with the datasheet.
For deployments where powered devices require 802.3at (30W class), the USW-ENTERPRISE-24-POE is the only model with a confirmed spec. The UISP-S-PRO's 802.3af rating limits per-port delivery and its aggregate budget is unspecified.
How do port speeds, switching capacity, and forwarding rate compare between the two switches?
The USW-ENTERPRISE-24-POE specifies 24 ports at 2.5G/1G PoE+ plus two 10G SFP+ uplinks, a switching capacity of 124 Gbps aggregate (62 Gbps non-blocking), and a forwarding rate of 92 Mpps. The dual SFP+ uplinks allow direct 10G fiber or DAC connection to a core switch or router.
The UISP-S-PRO specifies 24 Gigabit Ethernet PoE ports. No switching capacity, forwarding rate, or uplink port count/speed figures are provided in the available specifications. The port speed ceiling is 1 Gbps per access port, and no dedicated uplink ports are identified in the provided data.
For high-density camera or AP deployments where aggregate uplink bandwidth and non-blocking throughput are selection criteria, the USW-ENTERPRISE-24-POE supplies concrete, verifiable numbers (124 Gbps / 92 Mpps / 10G uplinks). The UISP-S-PRO's performance envelope cannot be assessed from the provided specifications.
What management capabilities, operating environment ratings, and compliance certifications does each model carry?
The USW-ENTERPRISE-24-POE specifies an operating temperature range of -5 to 40°C (23 to 104°F), SGCC steel enclosure, and certifications including NDAA compliance, CE, FCC, IC, and Anatel (05485-22-08356). VLAN support is documented at up to 1,000 VLANs. Management interface is listed as Ethernet in the provided specs.
The UISP-S-PRO specifies Web GUI and CLI management, SNMP support, and features including VLAN, QoS, Port Mirroring, and Link Aggregation per the datasheet-sourced fields. It also includes BLE (Bluetooth Low Energy). Operating temperature range, enclosure material, and regulatory certifications are not present in the provided specifications. NDAA compliance status is not stated.
For federally funded or government-adjacent projects where NDAA compliance is a contract requirement, only the USW-ENTERPRISE-24-POE carries a confirmed NDAA designation in the provided data. The UISP-S-PRO's explicit mention of CLI, SNMP, QoS, Port Mirroring, and Link Aggregation gives it a documented management feature set; the USW-ENTERPRISE-24-POE's management depth beyond VLAN count and Ethernet connectivity is not fully enumerated in the provided specs.
Which should you choose: the UISP-S-PRO or the USW-ENTERPRISE-24-POE?
Our take: The USW-ENTERPRISE-24-POE is the stronger choice when PoE power budget, port speed, and regulatory compliance are primary selection criteria. On power, it delivers a confirmed 400W PoE+ (802.3at) budget versus the UISP-S-PRO's 802.3af-only rating with no aggregate budget stated — a critical delta for PTZ cameras or dual-radio APs drawing up to 30W. On performance, it specifies 62 Gbps non-blocking throughput at 92 Mpps with dual 10G SFP+ uplinks, while the UISP-S-PRO provides no switching capacity or uplink speed data in the available specs. On compliance, the USW-ENTERPRISE-24-POE carries a confirmed NDAA designation; the UISP-S-PRO does not. The UISP-S-PRO may suit UISP-platform carrier or ISP edge deployments where 802.3af suffices and BLE-assisted provisioning or CLI/SNMP management is valued, but buyers cannot evaluate its full performance envelope without consulting the datasheet directly.

Frequently Asked Questions
Which should you choose: the UISP-S-PRO or the USW-ENTERPRISE-24-POE?
The USW-ENTERPRISE-24-POE is the stronger choice when PoE power budget, port speed, and regulatory compliance are primary selection criteria. On power, it delivers a confirmed 400W PoE+ (802.3at) budget versus the UISP-S-PRO's 802.3af-only rating with no aggregate budget stated — a critical delta for PTZ cameras or dual-radio APs drawing up to 30W. On performance, it specifies 62 Gbps non-blocking throughput at 92 Mpps with dual 10G SFP+ uplinks, while the UISP-S-PRO provides no switching capacity or uplink speed data in the available specs. On compliance, the USW-ENTERPRISE-24-POE carries a confirmed NDAA designation; the UISP-S-PRO does not. The UISP-S-PRO may suit UISP-platform carrier or ISP edge deployments where 802.3af suffices and BLE-assisted provisioning or CLI/SNMP management is valued, but buyers cannot evaluate its full performance envelope without consulting the datasheet directly.
Can the UISP-S-PRO power the same PoE devices as the USW-ENTERPRISE-24-POE?
Not necessarily. The USW-ENTERPRISE-24-POE supports PoE+ (IEEE 802.3at) at up to 30W per port with a 400W aggregate budget. The UISP-S-PRO is rated for PoE at IEEE 802.3af only, which caps per-port delivery at 15.4W. Devices that require 802.3at — such as many PTZ cameras and dual-radio APs — are not confirmed compatible with the UISP-S-PRO based on the available specifications.
Is either switch suitable for a government or federally funded security project requiring NDAA compliance?
Based on the provided specifications, only the USW-ENTERPRISE-24-POE carries a confirmed NDAA Compliant designation. The UISP-S-PRO specifications do not include an NDAA compliance statement. Installers working on projects with NDAA requirements should select the USW-ENTERPRISE-24-POE or verify the UISP-S-PRO's compliance status directly with Ubiquiti before specifying it.
Which switch is better suited for a high-density enterprise deployment with a core-layer uplink?
The USW-ENTERPRISE-24-POE is the better-documented choice for high-density enterprise use. It provides dual 10G SFP+ uplinks, 62 Gbps non-blocking switching capacity, 92 Mpps forwarding rate, and support for up to 1,000 VLANs — all confirmed in the available specifications. The UISP-S-PRO lists no uplink port specifications, switching capacity, or forwarding rate in the provided data, making a direct performance comparison impossible from specs alone.
