Juniper SRX5K-MPC3-100G10G 2x100GE 4x10GE Module | SRX5000, Expansion

Scale high-speed security infrastructure without replacing the platform. Juniper SRX5K-MPC3-100G10G is a plug-in expansion module for SRX5400, SRX5600, and SRX5800 systems, adding 2 x 100GE and 4 x 10GE ports to support dense uplinks, aggregation, and traffic growth. This module is built for environments where port density and optical connectivity matter as much as firewall policy. It gives architects a way to extend SRX5K capacity for high-bandwidth links while preserving the operational model of the existing chassis. That is especially valuable in data centers, service provider edges, and large enterprise cores where downtime and forklift upgrades are not acceptable. Compared with smaller interface cards, this module is aimed at teams that need to concentrate more traffic into fewer slots while keeping the platform aligned with modern backbone speeds. The 100GE ports support high-capacity uplinks, while the 10GE interfaces provide flexibility for aggregation and downstream connectivity. For procurement teams, it is a targeted expansion purchase that extends the life of an installed SRX5000 investment. Use it when the firewall must keep pace with faster transport layers, denser east-west traffic, and growing optical network demands. It is a practical way to add bandwidth where the chassis already has the security services and operational controls in place.
