HPE JL818A Aruba CX 4100i 24-Port Ethernet Switch

HPE JL818A – Aruba CX 4100i 24‑Port PoE+ Rugged Edge Switch

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.
