Aruba Instant On 1840 48G Class 4 Power over Ethernet 4 SFP - Smart-managed Layer 2+ Ethernet switch, White

The Aruba Instant On 1840 48G Class 4 PoE 4SFP switch is an unmanaged, plug-and-play device that requires no configuration to expand wired network capacity. It features 48 Gigabit Ethernet RJ-45 ports, with 24 PoE ports providing a total power budget of 370 W. Class 4 PoE simplifies the installation of access points, IP cameras, and VoIP phones by eliminating the need for individual power adapters. Four dedicated SFP slots allow for network expansion, providing high-speed fiber uplink connections to servers or core routers. Powering connected hardware through data cables centralizes electrical management across the network.

The 1U rack-mountable chassis is designed to integrate into standard server cabinets. The unit measures 443 x 253 x 44 mm and weighs 3.54 kg. With a 19 dB noise level, the switch is quiet enough for use near active workspaces. Front-panel LEDs indicate status, activity, speed, and full-duplex operation for immediate visual monitoring. A physical reset button allows for manual reboots during on-site troubleshooting, and the system supports firmware updates for future security and operational patches. At maximum load, the device draws 462.5 W from the mains.

• 104 Gbit/s switching capacity and a 77.37 Mpps forwarding rate ensure steady throughput under peak network load.
• 16,000-entry MAC address table for tracking and routing traffic across local networks.
• Auto-MDI/MDIX on all copper ports eliminates the need for crossover cables during installation.
• Support for jumbo frames allows for larger data packets, improving efficiency for bulk file transfers.
• 1.5 MB packet buffer memory helps prevent dropped packets during brief periods of congestion.
