SRX5K-SCB3 provided stable switching control within our chassis. System communication remained consistent even during peak loads.
Reliable switch control board for enterprise environments.
Improved internal switching stability.
Consistent chassis communication and uptime.
Dependable control board for SRX5K deployments.
Solid hardware ensuring smooth internal operations.
Stable backbone for SRX5K switching fabric.
Reliable performance across all installed modules.
The SRX5K-SCB3 is the third-generation control board for Juniper SRX5000 Series gateways, managing system control plane, routing protocols, and high-availability fail-over.
High-performance multi-core CPU, N+1 control-plane redundancy, hot-swap capability, secure boot, and real-time system monitoring via integrated LEDs.
Compatible with all Juniper SRX5000 Series chassis (SRX5100, SRX5500, SRX5800) that accept SCB3 modules; not supported on legacy SCB1/SCB2 slots.
Power down the chassis, slide the SRX5K-SCB3 into an empty SCB slot until it clicks, secure the captive screws, then power on and verify boot via CLI or front-panel LEDs.
