JG257A FlexFabric 5800-48G-PoE⁺ Ethernet Switch

The HPEJG257A, part of the FlexFabric 5800 series, is a robust Layer-3 managed Gigabit Ethernet Switch featuring 48 auto-sensing 10/100/1000 Mbps RJ-45 ports with PoE+ support, plus 4 x 10 GbE SFP+ uplink slots. Engineered for enterprise edge, distribution, or data center access layers, it delivers high throughput, flexible uplink options, and a full suite of routing and switching protocols×all in a compact 1U rack-mount design.

Features

Housed in a 1U rack-mount chassis, the 5800-48G-PoE⁺ offers a total of 48 front-facing Gigabit PoE+ ports for powering IP phones, wireless access points, security cameras, or other endpoints directly through Ethernet cabling. Four dedicated SFP+ expansion slots support 10 GbE uplinks, enabling high-speed aggregation to core layers or servers. A powerful Layer-3 architecture supports static routing, RIP, OSPF, and ECMP, delivering enterprise-class performance with low latency and cut-through switching capability

Advanced Options

With 512 MB SDRAM and 512 MB flash memory, this Ethernet Switchincludes advanced features such as VLAN segmentation, link aggregation, QoS prioritization, DHCP relay, SNMP v1/v2c/v3, sFlow, Telnet/CLI access, and RMON support. Fleet-wide management is facilitated via web GUI or CLI access. The Ethernet Switchincludes support for redundant, hot-swappable power supplies and fan trays, enhancing reliability in high-availability deployments. It is TAA-compliant and RoHS/WEEE certified.
