What PoE standard does the JG238A support?

IEEE 802.3at PoE+ across all 24 Gigabit ports, delivering up to 30W per port with intelligent allocation via auto-detection, class-based, LLDP-MED, or manual methods for efficient power delivery to APs, cameras, and VoIP devices.

What is the switching capacity and latency?

144 Gbps non-blocking switching capacity with up to 107.2 Mpps throughput. Latency measures <3.2 μs at 1 Gbps and <2.6 μs at 10 Gbps, ensuring wire-speed performance for enterprise access layer deployments.

Does this switch support stacking?

Yes, Intelligent Resilient Framework (IRF) stacking provides up to 96 Gbps full-duplex bandwidth using CX4 links. Multiple units operate as one logical switch with 50 ms failover for high availability and simplified management.

Is IPv6 supported on this model?

Full IPv6 support including dual-stack operation, IPv6 multicast, and routing features for future-proofing enterprise networks transitioning from IPv4 infrastructure.

What management interfaces are provided?

Web GUI, industry-standard CLI, SNMP v1/v2c/v3, RMON, and syslog. Supports centralized IRF management and Ethernet OAM (IEEE 802.3ah) for link monitoring and fault detection.

Product overview

The HPE JG238A 5500-24G-PoE+ SI Ethernet Switch is designed for enterprise campus and branch office networks requiring high-performance Gigabit Ethernet connectivity with Power over Ethernet Plus (PoE+) support. It features 24 autosensing 10/100/1000BASE-T RJ-45 PoE+ ports compliant with IEEE 802.3at, delivering up to 30W per port for powering IP phones, wireless access points, and cameras, along with 4 dual-personality Gigabit SFP ports for fiber uplinks. The switch provides a non-blocking 144 Gbps switching capacity with up to 107.2 Mpps throughput and low latency under 3.2 μs at 1 Gbps, supporting Layer 2 and basic Layer 4 features including VLAN tagging (4K VLANs), IP multicast snooping, voice VLAN, QoS with 8 queues, and jumbo frames up to 9216 bytes. Intelligent Resilient Framework (IRF) enables stacking up to 96 Gbps bandwidth for simplified management and high availability with 50 ms failover. Robust security includes ACLs, port security, and DHCP snooping. Ideal for convergence-enhanced networks with IPv6 support and advanced OAM for link monitoring. Rack-mountable 1U form factor suits standard 19-inch EIA cabinets.
