HPE JC065B 

12500 48‑Port Gig‑T LEC Expansion Module

The HPE JC065B is a high-density 48-port Gigabit Ethernet LEC (LAN Expansion Card) module designed for the ProCurve12500 Switch Series. Offering 10/100/1000Base‑T connectivity on each RJ‑45 port, this module boosts port density within the chassis without requiring external switches or cabling. Perfect for enterprise data centers or core/distribution layers, it supports server uplinks, aggregation, or high-performance edge connectivity. Administrators can add up to 48 copper Ethernet interfaces in a single module slot to expand capacity seamlessly. Ideal for environments where resilient Gigabit access is needed at scale, it integrates with full chassis features such as redundant supervisors, hot-swappable modules, and advanced routing services.

Features

This LEC Expansion Module installs directly into a line card bay within the ProCurve 12500 chassis, providing flexible expansion of copper connectivity. The JC065B delivers 48 RJ‑45 ports that auto-negotiate 10/100/1000 Mbps over twisted‑pair cabling, compatible with standard Cat5e/Cat6 infrastructure. By centralizing uplinks or access ports within the chassis, it helps optimize cabling management and streamlines network architecture in dense deployments Engineered for high availability and scalability, this module works with the ProCurve 12500’s distributed fabric architecture and Comware OS platform, supporting advanced protocols (IRF, MPLS, OSPF, BGP, VRRP, etc.). It enables in-service software upgrades (ISSU), non-stop forwarding, and hot patching—ensuring minimal disruption during maintenance or expansion

Advanced Options

Weighing approximately 3–6 kg depending on configuration, the module fits cleanly into chassis bay and draws power from shared power supplies, with full chassis redundancy. Compliance with RoHS and WEEE environmental standards ensures regulatory adherence. The JC065B pairs well with other high-speed modules and supervisor cards to deliver scalable, high-performance switching infrastructure in enterprise-grade networking environments.Built for high-availability enterprise networks, the JC065B module integrates tightly into the ProCurve 12500 chassis, which supports redundant supervisors, fabric modules, fans, and power supplies for seamless uptime. The module is hot-swappable—allowing live insertion or removal without system outage. Copper Gigabit ports are auto-sensing, simplifying deployment in mixed-speed environments. With all ports supporting full-duplex Gigabit, it delivers consistent performance for server aggregation, edge networking, or uplink spines within a chassis-based switching fabric
