Overview
The Juniper SRX5K-SCB3, part of the SRX5000 line, is a Switch Control Board designed to enhance the performance and reliability of network infrastructures. It features 10 Gigabit Ethernet technology, primarily through optical fiber media, supporting the 10GBase-X network technology. This board is equipped with two total expansion slots, specifically designed for SFP+ modules, providing flexibility in network connections and expansions.
At the core of the SRX5K-SCB3 is the I2C bus logic, which facilitates low-level communication with each component on the board. This is critical for monitoring and managing the health and performance of the network hardware. Additionally, the board includes component redundancy circuitry, ensuring continuous operation and minimizing downtime in case of component failure. Another key feature is the Control Board/Routing Engine mastership mechanism, which determines the active and standby statuses between the two, ensuring seamless operation and failover capabilities.
The hardware also boasts a Gigabit Ethernet switch connected to the embedded CPU complex, which is essential for managing internal data flow and processing. Moreover, the switch fabric integrated into the SRX5K-SCB3 provides the necessary switching functions for the Modular Port Concentrators (MPCs), enhancing the efficiency and speed of data routing within the network.
Control over the hardware is further extended through the Control field-programmable gate array (FPGA), which offers a Peripheral Component Interconnect (PCI) interface to the Routing Engine. This interface is crucial for high-speed data transfers and communication between the Routing Engine and other components. The board also includes circuits dedicated to chassis management and control, alongside power circuits designed to supply the Routing Engine and SCB3, ensuring stable operation under various conditions.
The SCB3 is designed with a slot specifically for the Routing Engine, underlining its role in centralizing network control and management functions. With a power requirement of 300 W and a weight of 9.6 lb (4.4 kg) when outfitted with the Routing Engine, this board is both efficient and relatively lightweight for its capability set.
- Supports 10 Gigabit Ethernet with optical fiber media.
- Features two SFP+ expansion slots for network flexibility.
- Incorporates I2C bus logic and component redundancy circuitry for enhanced reliability.
