HPE S0U78A Aruba CX 5420 8 Port SFP+ (1G/10G) LRM Module

Overview

The HPE S0U78A is a line-card module for the Aruba CX 5420 modular chassis, providing 8 SFP+ ports capable of 1 Gb or 10 Gb connectivity. It’s designed for fiber uplinks or distributed fiber access at the edge, where long-reach LRM optics are used. Because it runs under the AOS‑CX operating system within the 5420 chassis, you retain full Layer‑3 routing, automation, and high-availability features. In practice, it’s ideal for connecting to aggregation or core switches over fiber, or for distributing downstream fiber-connected devices in enterprise, campus, or branch deployments.

Key Features

• 8 × SFP+ ports (1G / 10G) — supports both legacy and modern uplinks.

• LRM-capable — compatible with long-reach multimode fiber optics.

• TAA-compliant — meets trade agreement act requirements for regulated procurement.
