Overview
The HPE JL818A (Aruba CX 4100i) is a 24-port Gigabit managed access switch designed for edge, industrial and harsh-environment deployments where you need robust wired connectivity plus high-speed uplinks. It supports 20 Class 4 (30 W) PoE+ ports and 4 Class 6 (60 W) PoE ports, with 4 × 10 Gb SFP+ uplinks, making it a good fit for connecting IP cameras, wireless access points and IoT devices in factory floors, substations or transportation racks. It fits neatly into existing rack or DIN-rail setups, and layers into the broader Aruba switching ecosystem.
Key Features
20 ports capable of IEEE 802.3at (Class 4, ~30 W) plus 4 ports capable of IEEE 802.3bt (Class 6, ~60 W) PoE on the RJ-45 interfaces, enabling mixed device power loads.
Four 10 Gb SFP+ uplink ports provide high bandwidth to core/distribution switches and prevent uplink bottlenecks.
Ruggedized chassis rated for industrial-edge use (extended temperature, IP30 rating), allowing operation in harsher environments beyond typical office racks.
Full Aruba AOS-CX management stack with static routing, ACLs, VLAN segmentation and no extra software licensing required, matching enterprise standards with industrial readiness.
