Detailed Specifications
HPE S0U73A - Aruba CX 5420 20-Port 1G Class-4 PoE + 4 SFP+ Module
Overview
The HPE S0U73A is a mixed-port line card for the Aruba CX 5420 modular chassis. It delivers 20 copper ports of 10/100/1000 with PoE Class 4, plus four SFP+ uplink ports that support 1 Gb or 10 Gb. This module is ideal when you need to power devices (like phones, APs, IoT) at the edge, while maintaining high-bandwidth uplinks via SFP+. In a practical deployment, it could handle dozens of PoE-powered access points or cameras while tying back to the core or aggregation layer through its SFP+ ports. It's built to run under AOS-CX, so you retain full Layer-3 routing and modern network automation features. The card is TAA-compliant, making it suitable for enterprise or regulated procurement, and fits into the CX 5420's 4U, 6-slot chassis.
Key Features
20× 1 Gb RJ-45 ports with Class 4 PoE, powering a broad array of edge devices.
4× SFP+ uplinks (1G/10G) for high-speed connectivity to aggregation or core switches.
Generous PoE budget (~600 W) to support multiple high-draw PoE devices.
Layer-3 functionality via AOS-CX, enabling OSPF, static routing, VRRP, and ACLs.
