Overview

About the Aruba CX 4100i 4100i 12-port 1GbE

Aruba CX 4100i Switch Series

The Aruba CX 4100i Switch Series is a modern family of ruggedized Ethernet switches ideal for connecting IoT, access points, and user devices in harsh environments. Created for high performance, reliable, and secure access, the Aruba CX 4100i switches provide versatile deployment options for enterprise networks extending beyond carpeted areas to challenging outdoor and industrial spaces.

Based on the programmable AOS-CX operating system used across the Aruba CX portfolio for a more efficient operator experience, this IP30 ruggedized series operates in extended temperatures, provides protection for sub-station applications with IEC 61850-3 and IEEE 1613 compliance, and has high tolerances for railway applications.

This Layer 2 access switch has convenient built-in high speed uplinks, supports combination of 30W and 60W PoE with up to a 360W power budget, and relies on passive cooling for the fan less 12 port DIN rail mount model and fan less 24 port 1U rack mount model. With enhanced access security, traffic prioritization, and IPv6 support, the Aruba CX 4100i also simplifies ownership and brings peace of mind with no switch software licensing requirements.

As part of Aruba's Edge Services Platform (ESP), Aruba CX switches play a foundational role in the Unified Infrastructure. Automation, embedded analytics, high availability, and secure segmentation are designed into CX switches with Aruba Central delivering a unified, single view of the network that maximizes operational efficiency across enterprise networks. Aruba Dynamic Segmentation extends Aruba's foundational wireless role-based policy capability to Aruba wired switches. What this means is that the same security, user experience and simplified IT management can be enjoyed throughout the network. Regardless of how users and IoT devices connect, consistent policies are enforced across wired and wireless networks, keeping traffic secure and separate.
