Detailed Specifications
HPE JG555A 5920AF-24XG 24-Port 10 Gb SFP+ Layer 3 Switch
Overview
The HPE JG555A is a rack-mount 1U Layer 3 switch designed for data centre access and top-of-rack deployment, used by network engineers needing full 10 Gb SFP+ connectivity for server uplinks and high-density aggregation. It offers 24 fixed 1/10 Gb SFP+ ports, delivering high throughput and large routing tables suitable for demanding virtualised environments. It supports full L2 and L3 functionality with IPv4/IPv6 dual-stack, IRF virtualisation for multi-switch clustering and deep packet buffering to handle bursty server-to-server traffic. Its intended placement is in enterprise or campus data-centres where high bandwidth and scalability are required. It integrates into HPE FlexFabric networking architecture and supports centralised management via HPE IMC or CLI.
