Aruba 4100i 12-port 1GbE (8-port Class 4 POE and 4-port Class 6 POE) 2-port SFP+ DIN Mount Switch (JL817A)
Ruggedized Ethernet access switch

Overview:

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 implifies 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.

• Ruggedized Layer 2 switch series provides high performance, fully manageable, and reliable, Ethernet connectivity to IoT, access points, and user devices in harsh environments. Versatile form factors with fast 1/10GbE uplinks deliver both 30W and 60W PoE to improve IoT power.


• Layer 2 feature set with static routing and no switch software licensing required.


• Aruba Dynamic Segmentation 1 enables enhanced security and simplified access for users and IoT.


• Management flexibility with support for Aruba Central, easy-to-use Web GUI, CLI, and Aruba NetEdit.

Features:

Ruggedized Aruba CX Switches

The Aruba CX 4100i Switch Series provides IP30 Ethernet connectivity with high speed uplinks, 30W and 60W PoE, to securely extend the enterprise network and support IoT in harsh environments.

Using Aruba AOS-CX operating system across Aruba CX switching platforms and deployment domains provides a simpler, more consistent operator experience.

Achieve versatile deployment with fan less 12 port DIN rail mount and 24 port 1U rack mount models with built-in 1/10GbE uplinks and up to 360W Class 4 and Class 6 PoE.

Fully-managed enterprise class switches deliver Layer 2 capabilities with support for static routing, ACLs, robust QoS, traffic prioritization, and IPv6 support.

Simplifies ownership with no switch software licensing or subscriptions required.

Performance and Power

The Aruba CX 4100i Switch Series is designed with Aruba ASICs that deliver very low latency, increased packet buffering, and adaptive power consumption.

Deploy IoT devices and wireless access points in harsh environments with models that support up to 360W IEEE 802.3at Class 4 and IEEE 802.3.bt Class 6 Power over Ethernet.

Built-in wire speed 1/10GbE uplinks remove bottlenecks at the access layer where devices connect.

Operational in extended temperatures from -40°C to 70°C using Aruba's industrial transceivers.

Simplified Configuration and Management

The Aruba CX 4100i Switch Series provides flexibility to manage and simplify configurations with Aruba NetEdit, easy to use built-in web GUI, or industry standard CLI.

Aruba NetEdit introduces automation that allows for rapid network-wide changes and verifies policy conformance post network updates.

Software-defined ready with REST APIs for fine-grained programmability of network tasks.

Smarter Segmentation

The Aruba CX 4100i Switch Series supports Aruba Dynamic Segmentation that automatically applies and enforces user, device, and application-aware policies on Aruba wired and wireless infrastructures.

Automated device profiling, role-based access control, and Layer 7 firewall features deliver enhanced visibility and performance for a better overall experience for both IT and end-users alike.

Reduces time-consuming and error-prone task of adds, moves and changes.
