Description
Aruba Instant On 1930 48G Class4 PoE 4SFP/SFP+ 370W Smart Switch (Part Number: JL686A) is an enterprise-class, high-density Layer 2+ Gigabit PoE+ switch engineered for demanding enterprise campus networks, educational facilities, and large commercial venues. It provides 48 autosensing 10/100/1000BASE-T Class 4 PoE/PoE+ ports and 4 dedicated 1G/10G SFP/SFP+ optical transceiver slots for ultra-fast backbone aggregation. Featuring a non-blocking 176 Gbps switching capacity and a forwarding rate of 130.95 Mpps, it is powered by a robust 370W PoE budget to drive high-density IP surveillance systems, Wi-Fi 6 access points, and VoIP communications.
The 1930 48G PoE+ 370W features smart variable-speed cooling fans that automatically optimize airflow and keep acoustic noise to a minimum. It delivers enterprise-grade Layer 2+ capabilities, including IPv4 static routing (up to 32 routes), 802.1Q VLANs, link aggregation, and IEEE 802.1X network access control. Network administrators can easily configure, monitor, and troubleshoot the switch remotely from any mobile device using the Aruba Instant On mobile application or cloud web portal without software licensing fees.
