The Juniper Networks SRX5K-MPC3-40G10G Input/Output Card (IOC) is a high-performance, multi-rate interface module designed for Juniper SRX5400, SRX5600, and SRX5800 Services Gateways. Built to support demanding security and networking environments, this IOC delivers an optimal balance of port density, throughput, and scalability for service providers and large enterprise data centers.
Featuring 24 × 10GbE SFP+ ports and 6 × 40GbE QSFP+ ports, the SRX5K-MPC3-40G10G enables seamless integration of high-density aggregation and high-speed uplinks within a single slot. With a total throughput of up to 240 Gbps (full duplex), it is engineered to handle heavy traffic loads while maintaining consistent, wire-rate performance.
Powered by the advanced Juniper Trio chipset, this IOC delivers robust Layer 2 and Layer 3 capabilities, including deep packet buffering, advanced QoS, and efficient traffic handling, ensuring optimized data flow before traffic is processed by Services Processing Cards (SPCs). This architecture enhances overall system performance and supports large-scale deployments with massive session counts and complex security policies.
The SRX5K-MPC3-40G10G provides flexibility for evolving network infrastructures, allowing organizations to combine 10GbE aggregation ports with 40GbE uplinks for high-speed connectivity to core networks or data center fabrics. It supports a wide range of optical transceivers and DAC cables, enabling both short- and long-distance connectivity options.
Designed for high availability and operational efficiency, the module features a hot-swappable design, allowing installation or replacement without disrupting network services. When paired with the SRX5K-SCB3 switch control board, it delivers optimal performance and scalability for next-generation security architectures.
Integrated with Junos OS, the Juniper SRX5K-MPC3-40G10G is an ideal solution for high-performance firewalling, VPN services, and secure data center interconnect, providing the reliability, flexibility, and throughput required for modern network security infrastructures.

FAQs:
Q1. Can I use the 40GbE ports as 10GbE ports?
Yes. Depending on the Junos version and configuration, the QSFP+ ports can typically be channelized using breakout cables to provide four 10GbE interfaces per port.
Q2. Does this card require the SCB3?
While it may operate with an SCB2, the SRX5K-SCB3 is highly recommended (and often required depending on the chassis configuration) to provide the necessary backplane bandwidth to support the 240 Gbps throughput of this card.
Q3. Is this card compatible with SPC2 or SPC3?
The MPC3-40G10G is compatible with both SPC2 and the high-performance SPC3. However, to realize the full throughput potential of the card, it is best paired with SPC3 modules.
Q4. Does this card support MACsec?
Support for MACsec is dependent on the specific hardware revision and Junos release. Generally, this card focuses on high-density transport rather than link-layer encryption.
Q5. Are the transceivers included?
No. SFP+ and QSFP+ transceivers (SR, LR, etc.) are sold separately and should be selected based on your fiber distance and cabling requirements.
