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.
Yes, with N+1 redundancy configured, you can remove and replace the SCB3 module while the secondary control board maintains full forwarding and management services.
Yes, the SCB3 supports active/passive and active/active redundancy, enabling seamless fail-over and zero-packet-loss policy enforcement.
Typical power consumption is 60 W; the chassis’ shared fans and power supplies provide adequate cooling and redundancy per Juniper SRX5K installation guidelines.
The SRX5K-SCB3 has an MTBF (Mean Time Between Failures) of over 100,000 hours under standard operating conditions.
Operating temperature: 0 °C to 55 °C; humidity: 5%–90% non-condensing; altitude: up to 5,000 m per IEC 60850-1 standards.
Upload the latest Junos OS image to the chassis, set the boot media to SCB3, then execute “request system software add” via CLI; the SCB3 firmware auto-installs on next reboot.
Juniper provides a limited one-year hardware warranty, covering defects and offering advanced replacement options with an active Juniper support contract.
Download the “Juniper SRX5000 Series Hardware Guide” and “Junos OS Administration Guide” from the Juniper Support portal under the SRX5K documentation section.
Check front-panel LEDs for status codes, review “show chassis hardware” and “show system alarms” in CLI, then consult Juniper KB articles for specific error resolutions.
Yes, it meets FCC Part 15, CE, UL/CSA, RoHS, and NEBS Level 3 certifications for safety, EMI, and environmental compliance.
The SCB3 enhances control-plane processing capacity by 30%, accelerates routing convergence, and supports up to 1 million sessions in the forwarding plane.
Contact your Juniper account manager or authorized reseller with SKU SRX5K-SCB3; provide chassis serial number for compatibility verification.
Use “show chassis firmware firmware-level” and “show chassis environment” CLI commands or Junos Space Network Management Platform to view SCB3 status indicators and logs.
