What is the switching performance?

The switch provides a 104 Gbps nonblocking architecture with up to 77.4 million pps throughput and latency under 3 µs. It supports jumbo frames up to 10K bytes and hardware ACLs for secure wire-speed operation.

Does it support VLANs and Layer 3 features?

Yes, it supports IEEE 802.1Q with 4,094 VLAN IDs and an 8K MAC address table. As a static Layer 3 switch, it offers basic IPv4/IPv6 routing with 32 entries, trunks up to 26x8 links, and IPv6 ACLs.

Is it rack-mountable and what are dimensions?

Rack-mountable in 1U height, dimensions are approximately 17.3(w) x 10.24(d) x 1.72(h) inches (43.94 x 26.01 x 4.36 cm). It fits standard 19-inch racks for enterprise data centers.

What management and reliability features are included?

Includes Ethernet OAM (IEEE 802.3ah) for link monitoring, smart link for 50 ms failover, flow control (IEEE 802.3x), and serial console. Comprehensive QoS and security policies enhance manageability.

Is PoE supported on this model?

No, the HPE 5120-48G SI (JE072-61201) is a non-PoE model focused on data switching. PoE+ variants like JG091B exist for powered devices, but this prioritizes pure Gigabit performance.

Product overview

The HPE 5120-48G SI Switch (SKU: JE072-61201) is a fully managed Layer 3 Gigabit Ethernet switch from the HPE 5120 Series, designed for enterprise access and distribution layers. It features 48 RJ-45 autosensing 10/100/1000BASE-T ports and 4 fixed Gigabit Ethernet SFP ports, supporting nonblocking 104 Gbps switching fabric and up to 77.4 million pps throughput. Rack-mountable in a 1U form factor, it provides high-density connectivity with an 8K MAC address table, 4,094 VLAN support, and jumbo frames up to 10K bytes for efficient large data transfers. Key capabilities include Ethernet OAM for link monitoring, comprehensive IPv6 support, hardware-based ACLs for security, and diversified QoS policies. Ideal for Gigabit to the desktop in enterprise networks or MAN distribution, it ensures wire-speed forwarding, redundancy via smart link failover (50 ms), and simplified management through serial console and standard protocols. This entry-level static Layer 3 switch enhances network reliability and performance without PoE.
