  • Rugged IP30 design withstands harsh industrial environments
  • Fanless passive cooling enables silent operation in noise-sensitive areas
  • 12 PoE ports deliver up to 360 W power budget for devices
  • IEC 61850-3 and IEEE 1613 compliance suits substation deployments
  • AOS-CX OS provides consistent management across the Aruba CX portfolio

Industrial Ethernet Access Switch

The Aruba CX 4100i JL817A is a 12-port ruggedized switch built for industrial and outdoor deployments where standard office gear cannot survive. It targets network teams extending enterprise connectivity to factory floors, railway waysides or utility substations. The IP30-rated enclosure and fanless design allow operation across extended temperature ranges without moving parts to fail.

Layer 2 Access with PoE Budget

This model delivers Layer 2 switching with built-in high-speed uplinks and a 360 W PoE budget that can mix 30 W and 60 W ports for cameras, sensors and wireless access points. Passive cooling removes airflow requirements, so the switch fits sealed cabinets or DIN-rail mounts where dust, vibration or moisture rule out active fans. Software licensing is not required for the switching feature set.

DIN-Rail Mounting and Standards Compliance

The fanless 12-port chassis mounts on a DIN rail, saving rack space in compact enclosures while meeting IEC 61850-3 and IEEE 1613 for substation environments. Compliance with railway tolerances means vibration and shock resistance are validated for trackside use. Copper uplink ports provide deterministic latency for time-sensitive industrial protocols without relying on fibre transceivers.

Highlights
