Switch Control Board SRX5K-SCB3 Overview
The SRX5K-SCB3 (SCB3) caters to high-end security markets requiring support for higher
capacity traffic, greater interface density (slot and capacity scale), and improved services.
The SCB3 is supported on SRX5400, SRX5600, and SRX5800 Services Gateways.
The SCB3 supports the standard midplane and the enhanced midplane.
Some key attributes of the SCB3 are:
•
With the existing midplane and fabric link speed of 8.36 Gbps, supports a bandwidth
of 205 Gbps per slot with redundant fabric support and 308 Gbps per slot without
redundancy.
•
With the enhanced midplane and fabric link speed of 10.2 Gbps, supports a bandwidth
of 249 Gbps per slot with redundant fabric support and 374 Gbps per slot without
redundancy with the enhanced midplane
•
Improved fabric performance with the next-generation fabric (XF2) chip.
•
Full performance with fabric redundancy for higher-capacity line cards.
•
Support for MPC line cards such as SRX5K-MPC (IOC2) and IOC3
(SRX5K-MPC3-40G10G or SRX5K-MPC3-100G10G) only.
•
Two 10-Gigabit Ethernet SFP+ ports (These ports are disabled and reserved for future
use).
The Routing Engine installs directly into a slot on the SCB3, as shown in
.

Routing Engine SRX5K-RE-13-20 Overview
The Routing Engine is an Intel-based PC platform that runs Junos OS. Software processes
that run on the Routing Engine maintain the routing tables, manage the routing protocols
used on the device, control the device interfaces, control some chassis components, and
provide the interface for system management and user access to the device (see
A USB port on the Routing Engine accepts a USB memory card that allows you to load
Junos OS.
