Questions & Answers
What is the SRX5K-SCB3 Switch Control Board?
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.
What are the key features of the SRX5K-SCB3?
High-performance multi-core CPU, N+1 control-plane redundancy, hot-swap capability, secure boot, and real-time system monitoring via integrated LEDs.
Which SRX platforms are compatible with the SRX5K-SCB3?
Compatible with all Juniper SRX5000 Series chassis (SRX5100, SRX5500, SRX5800) that accept SCB3 modules; not supported on legacy SCB1/SCB2 slots.
How do I install the SRX5K-SCB3 in my SRX chassis?
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.
Can I hot-swap the SRX5K-SCB3 without service interruption?
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.
Does the SRX5K-SCB3 support control-plane redundancy?
Yes, the SCB3 supports active/passive and active/active redundancy, enabling seamless fail-over and zero-packet-loss policy enforcement.
What are the power and cooling requirements?
Typical power consumption is 60 W; the chassis’ shared fans and power supplies provide adequate cooling and redundancy per Juniper SRX5K installation guidelines.
What is the MTBF of the SRX5K-SCB3?
The SRX5K-SCB3 has an MTBF (Mean Time Between Failures) of over 100,000 hours under standard operating conditions.
What environmental specifications apply to the SRX5K-SCB3?
Operating temperature: 0 °C to 55 °C; humidity: 5%–90% non-condensing; altitude: up to 5,000 m per IEC 60850-1 standards.
How do I upgrade the firmware on the SRX5K-SCB3?
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.
What warranty does Juniper offer for the SRX5K-SCB3?
Juniper provides a limited one-year hardware warranty, covering defects and offering advanced replacement options with an active Juniper support contract.
Where can I find the SRX5K-SCB3 installation and configuration guide?
Download the “Juniper SRX5000 Series Hardware Guide” and “Junos OS Administration Guide” from the Juniper Support portal under the SRX5K documentation section.
How do I troubleshoot SRX5K-SCB3 initialization errors?
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.
Is the SRX5K-SCB3 compliant with industry standards?
Yes, it meets FCC Part 15, CE, UL/CSA, RoHS, and NEBS Level 3 certifications for safety, EMI, and environmental compliance.
What performance impact does the SCB3 have on the SRX5K platform?
The SCB3 enhances control-plane processing capacity by 30%, accelerates routing convergence, and supports up to 1 million sessions in the forwarding plane.
How do I order a replacement SRX5K-SCB3?
Contact your Juniper account manager or authorized reseller with SKU SRX5K-SCB3; provide chassis serial number for compatibility verification.
How can I monitor the health status of the SRX5K-SCB3?
