The SRX5K-SCB3-BB is a Switch Control Board (SCB3) designed for the Juniper SRX5000 line, providing integrated control-plane functions and base chassis management.
The SCB3 control board is compatible with SRX5400, SRX5600, and SRX5800 service gateway chassis when installed in the base slot.
Key features include dual control-plane CPUs, redundant management ports, in-band and out-of-band management, and support for Junos OS high availability.
Power down the SRX5000 chassis, slide the SCB3 into the base slot until it clicks, secure the retaining screws, then power up the chassis to auto-detect the board.
No, the SCB3 is sold as a hardware component; Junos OS licenses and feature licenses must be purchased separately.
No, the SCB3 must be installed or replaced when the chassis is powered down to ensure safe insertion and proper initialization.
The SCB3 control board consumes up to 80 watts under typical operating conditions.
Yes, when paired with an SCB3 in a dual-control-plane configuration, the SRX5K supports active/backup redundancy for nonstop control-plane operations.
The SCB3 is UL, CE, FCC, and RoHS compliant and meets NEBS Level 3 requirements for carrier-grade installations.
Standard lead time is 2–4 weeks, depending on stock availability and shipping destination.
Use the Junos CLI to set up out-of-band management via mgmt0 or in-band management on fxp0 interfaces with commit commands.
Juniper offers a one-year limited hardware warranty covering defects in materials and workmanship.
Download the latest Junos OS releases and SCB3 firmware from the Juniper Customer Support Portal using your account credentials.
Connect to the console port, review boot logs for error messages, verify power rails, and replace the control board if hardware faults persist.
Yes, you can upgrade by replacing the SCB2 in the base slot with the SCB3 and updating to a supported Junos OS version.
