Product overview

The HPE A5120-48G SI Switch (JE072A), part of the FlexNetwork 5120 SI Series, is a managed Layer 3 Ethernet switch designed for enterprise access and distribution layers. It features 48 RJ-45 autosensing 10/100/1000 Mbps ports and 4 fixed Gigabit Ethernet SFP ports, supporting cabling types including Ethernet 10Base-T, 100Base-TX, and 1000Base-T. With an 8K MAC address table, IEEE 802.1Q VLAN support for 4,094 IDs, up to 77.4 Mpps throughput, and latency under 3 µs at 1000 Mb, it ensures high-performance wire-speed switching. Management options include web browser interface, SNMP, and secure HTTPS GUI, with protocols like IPv6, ACLs, IGMP, and Ethernet OAM. The 1U rack-mountable form factor houses an internal fixed AC power supply. Ideal for medium to large enterprise networks, it supports static IPv4 routing, stacking via IRF for resilience, and simplifies operations with IMC integration, enhancing availability and reducing complexity.
