HPE S0U61A – Aruba CX 5420 24‑Port 1 Gb RJ‑45 Access Module
Overview
The HPE S0U61A is a 24-port 10/100/1000 Mbps RJ-45 line card built for the Aruba CX 5420 modular chassis. It’s a straightforward, non‑PoE access layer module that delivers cost‑efficient gigabit connectivity where power over Ethernet isn’t required. Ideal for access closets, campus edge, or branch deployments, this card plugs into the 5420 chassis and leverages the AOS‑CX operating system for full Layer‑3 routing, automation, and VSX high-availability. Because it’s part of the modular chassis, it provides growth flexibility — mix it with other cards (PoE, fiber, high-speed) as your network evolves.
