Description

The Juniper SRX5000 Series SCB3 Switch Control Board (Redundant Option) is a high-capacity fabric module designed for SRX5400, SRX5600, and SRX5800 enterprise firewalls demanding maximum throughput and resilience. Installed in SCB slot 2 or 6, this redundant variant maintains full system performance even under fabric failure, delivering up to 374 Gbps per slot on an enhanced midplane. Featuring Juniper's next-generation XF2 fabric chip and fabric link speeds up to 10.2 Gbps, the SCB3-R ensures uninterrupted traffic forwarding for high-density service provider and large enterprise environments.

The SCB3-R supports both standard and enhanced midplane configurations and is compatible with the full range of SRX5000 MPC line cards including IOC2, IOC3, and IOC4 variants. It monitors critical system functions such as fan speed, board power status, and PDM status, while providing chassis-wide interconnection across all installed MPCs. Requires Junos OS 15.1X49-D10 or later for redundant SCB operation on SRX5800 platforms. Buy today from iptrading.com.au — fast shipping and expert service across Australia.

FAQs

Q: What is the difference between the SRX5K-SCB3 and the SRX5K-SCB3-R?
A: The SRX5K-SCB3-R is the Redundant Option variant of the SCB3. It installs in SCB slot 2 or 6 to provide fabric redundancy alongside the primary SCBs in slots 0 and 1. The redundant configuration ensures full system performance is maintained if a primary SCB fails, making it essential for mission-critical deployments.

Q: Which SRX5000 chassis models support the SRX5K-SCB3-R?
A: The SRX5K-SCB3-R is compatible with the SRX5400, SRX5600, and SRX5800 firewall chassis. For redundant SCB operation on the SRX5800, Junos OS 15.1X49-D10 or later is required.

Q: What MPC line cards are supported with the SCB3-R?
A: The SCB3-R supports SRX5000 MPC line cards including IOC2 (SRX5K-MPC), IOC3 variants (SRX5K-MPC3-40G10G and SRX5K-MPC3-100G10G), and IOC4 variants, enabling high-density interface configurations in the chassis.

Q: Does the SRX5K-SCB3-R support enhanced midplane configurations?
A: Yes. The SCB3-R supports both standard and enhanced midplane configurations. With an enhanced midplane, it delivers fabric link speeds of up to 10.2 Gbps and up to 374 Gbps per slot in non-redundant mode, providing significantly higher capacity for demanding environments.

Q: Can I purchase the SRX5K-SCB3-R in Australia?
A: Yes. iptrading.com.au stocks Juniper SRX5000 Series modules and accessories for B2B customers across Australia. We offer fast shipping and expert pre-sales and post-sales support. Contact our team for availability, lead times, and volume pricing.

Q: What system management functions does the SCB3 perform?
A: The SCB3 monitors and controls critical chassis functions including fan speed, board power status, and PDM (Power Distribution Module) status. It also provides fabric interconnections to all MPCs within the chassis, acting as the central switching and control plane for the SRX5000 platform.
