Juniper EX9200-15C 15x 100GbE Line Card with MACsec | Enterprise Switching

Scale secure aggregation and core switching with a line card designed for high-density 100GbE connectivity. The Juniper EX9200-15C adds 15 x 100GbE ports to EX9200 modular systems, giving infrastructure teams the bandwidth headroom needed for east-west traffic, data center interconnect, and high-speed campus backbones. MACsec support helps protect traffic in motion without forcing a separate security layer into the path, which is valuable when encryption must coexist with low-latency forwarding. In modular environments, that balance matters: you get the port density required for growth, while preserving the operational model of a chassis platform already built for scale. This line card is a fit for organizations standardizing on Juniper EX9200 infrastructure and looking to expand capacity without replacing the switching fabric. It is the kind of component that justifies its place in the chassis by delivering more usable bandwidth, stronger link security, and a cleaner upgrade path than lower-density alternatives.
