Hewlett Packard Enterprise JD199B Switch Module

The HPE JD199B Switch Module from the HPE 7500 Series expands Gigabit Ethernet copper port capacity, delivering 48 x 10/100/1000 RJ-45 ports (Port Configuration) to support scalable network expansion in enterprise LANs, campus networks, data centers, and industrial Ethernet environments. Maintenance teams and system integrators rely on this part for switch expansion, module replacement, network upgrades, and restoring reliable port availability, with common deployments in core switches, aggregation switches, campus networks, and industrial environments that require scalable high-density wired connectivity. Designed for core, aggregation, and access-layer deployments, it enables edge device connections and uplink aggregation, with PoE-ready deployments available when paired with a compatible chassis and power setup. This hot-swappable copper Ethernet expansion module (Form Factor: Expansion module / line card) provides 1 GbE per port and is compatible with HPE 7500 Series switches to restore port availability and support network upgrades. Alternate Part Number JD199A; common replacements include HPE JD234A 7500 24-port Gigabit SFP Extended Module.
