Aruba CX 4100i 12p 1GbE 8p Class4 PoE and 4p Class6 PoE 2p SFP+ DIN Mount Switch

Overview

The Aruba JL817A is a DIN mount network switch designed to deliver robust connectivity and power in environments where dust, vibration, or extreme temperatures challenge typical wiring-closet equipment. It features 12 copper Ethernet ports with differentiated power output—eight ports supply up to 30 watts each, while four ports provide up to 60 watts for demanding devices like outdoor access points and PTZ cameras. Two SFP+ slots support 1 or 10 gigabit uplinks, ensuring high-speed backhaul without bottlenecks. Its fanless design and wide operating temperature range from -40 to 75 °C make it ideal for installation in control panels, roadside cabinets, or factory floors where space and cooling are limited.

Key features
