Juniper EX9200-40XS 40-Port 10GbE SFP+ Line Card | MACsec Switch

Build secure high-speed switching capacity into an EX9200 chassis with the EX9200-40XS line card. It provides 40 10GbE SFP+ ports and MACsec support, giving network architects a way to scale encrypted connectivity without sacrificing port density. That combination is valuable in environments where traffic protection is mandatory and uplink count drives design decisions. This module fits organizations that need more than basic transport. MACsec helps protect data in motion at the link layer, which is especially important for aggregation paths carrying sensitive workloads, regulated traffic, or inter-building links. By keeping encryption close to the switching fabric, you reduce exposure while maintaining the performance profile expected from 10GbE infrastructure. The modular line card approach also supports disciplined lifecycle planning. Instead of replacing an entire switch platform to gain more high-speed ports, teams can extend the existing EX9200 chassis with a purpose-built module. That preserves operational consistency, simplifies expansion, and supports procurement strategies centered on long-lived infrastructure assets.
