Detailed Specifications
HPE R0X38B - 48-Port 1 Gb PoE+ Module (Class 4)
Overview
The HPE R0X38B is an access-layer expansion module designed for the Aruba CX 6400 family of modular chassis. If you already operate a 6400-series chassis and need to add a dense block of copper-based access ports supporting PoE+, this module gives you 48 RJ-45 ports at 1 Gb each with Class 4 PoE (up to ~30 W per port) to power devices such as Wi-Fi access points, VoIP phones or IP cameras. It fits directly into the chassis slot and integrates with chassis-level management, power and redundancy. The module is ideal for campus or branch wiring closets where high port-density and power-enabled access are required and you want to leverage your existing chassis investment.
Key Features
48 × 10/100/1000 Mb RJ-45 ports with Class 4 PoE support×delivers power to access devices without extra injectors.
Designed for Aruba CX 6400 modular chassis×slots into the chassis plate and integrates with existing modules.
Enables high-density access for copper-connected endpoints while centralizing management and power supply.
Simplifies access-layer wiring: one module handles large port count with power support, reducing number of standalone switches.
Ideal for branches or wiring closets with many powered endpoints, while enabling uplinks/backhaul to higher layers via the chassis.
