MX2008 SFB2 Redundancy
Seven out of eight MX2008 SFB2 boards are required for line-rate operation. The system can continue
operating with fewer than seven SFB2s, but forwarding performance is impacted.
MX2008 SFB2 Components
Each MX2008 SFB2 consists of the following components:
One PF fabric chip per card
PCIe control of one PF ASIC
I2C bus logic interface, used for component management and monitoring of temperature, and voltage
Switch fabric—Provides the switching functions for the MPCs
Fabric capacity—MX2008 SFB2 supports 2000 Gbps per slot throughput without redundancy
Circuits for chassis management and control
Power circuits for the MX2008 SFB2
LED—Provides status of the MX2008 SFB2
