Detailed Specifications

HP JG236A 

5120‑24G‑PoE+ Managed switchGigabit Switch – 24× PoE+ + 4× Shared SFP Ports, Layer 3

The 5120‑24G‑PoE+ switch (JG236A) delivers comprehensive access-layer networking with 24 auto-sensing 10/100/1000BASE‑T PoE+ ports and 4 dual‑personality shared SFP ports. Ideal for edge deployments in SMB and enterprisenetworks, it supports static Layer 3 routing (IPv4/IPv6), IRF stacking, and advanced QoS and ACL controls. With a centralized PoE+ power budget of up to 370 W, this robust 1U switch simplifies deployment of IP phones, wireless APs, and surveillance cameras while offering scalability and performance in a resilient chassis.

Features

This managed Layer 3 Ethernet switch supports static IPv4/IPv6 routing, ACL-based security, and quality-of-service (QoS) features like traffic classification and policing. It enables high reliability through IRF stacking—up to four units configured as a single logical switch with cross-rack stacking over long distances. Two interface slots allow optional 10 GbE expansion modules. The four dual‑personality ports can operate as either RJ‑45 or SFP, offering flexible optical uplinks or copper connections.

Advanced Options

Full management support includes CLI, web GUI, SNMP, RMON, SSH, and integration with HP Intelligent Management Center (IMC). Traffic analytics and link visibility are enhanced via sFlow, port mirroring, and storm control. It is ideal for campus access, server farm edge, or PoE‑powered device aggregation.

Product Key Features

    • 24 × 10/100/1000 Mbps PoE+ RJ‑45 ports

    • 4 dual‑personality RJ‑45/SFP ports

    • Static Layer 3 routing with IPv4/IPv6 support

    • IRF stacking supports up to 4 devices as one logical switch

    • Up to 370 W total PoE+ power budget

    • Dual interface module slots for optional 10 GbE expansion

Reliability & Performance

With a switching capacity of approximately 144 Gbps and forwarding rate around 107.2 Mpps, this switch provides low-latency, line-rate performance. Latency is <3.2 µs at Gigabit speeds and <2.6 µs over 10 GbE ports. Onboard memory includes 128 MB SDRAM and 16 MB flash with 2 MB packet buffer. It supports jumbo frames up to 9,216 bytes and maintains a 16K MAC address table. PoE+ operation delivers up to 370 W for powered devices. Power efficiency and stack-level redundancy ensure high availability. Engineers can configure airflow direction and election modules for rack-optimized thermal performance. IRF stacking improves uptime and simplifies network expansion.
