Description
Aruba Instant On 1930 48G 4SFP/SFP+ Smart-Managed Switch (Part Number: JL685A) is a high-density enterprise-class Layer 2+ smart-managed Gigabit switch designed for corporate office backbones, educational campuses, and mid-sized commercial organizations. It delivers 48 autosensing 10/100/1000BASE-T Gigabit RJ-45 ports and 4 dedicated 1G/10G SFP/SFP+ optical transceiver slots for ultra-fast fiber uplinks to core network infrastructure. Delivering an impressive non-blocking 176 Gbps switching capacity and a packet forwarding rate of 130.95 Mpps, it accommodates high volumes of concurrent network traffic with ease.
The 1930 48G incorporates an innovative thermal architecture that provides fanless silent 0 dB operation, a rare engineering breakthrough for a full 48-port Gigabit switch. It provides robust Layer 2+ management features, including IPv4 static routing (up to 32 static routes), 802.1Q VLAN segmentation, link aggregation, and IEEE 802.1X security. Network setup and remote cloud administration are seamlessly orchestrated via the Aruba Instant On mobile app or web portal without requiring subscription licenses.
