Switch Control Board Srx5K-Scb3 Specifications - Juniper SRX5400 Hardware Manual

• 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

SRX5K-SCB3 LEDs | 52
Each SRX5K-SCB3 (SCB3) consists of the following components:
• I2C bus logic for low-level communication with each component
• Component redundancy circuitry
• Control Board/Routing Engine primary-role mechanism
• Gigabit Ethernet switch that is connected to the embedded CPU complex on all components
• Switch fabric to provide the switching functions for the MPCs
• Control field-programmable gate array (FPGA) to provide the Peripheral Component Interconnect
(PCI) interface to the Routing Engine
• Circuits for chassis management and control
• Power circuits for the Routing Engine and SCB3
