Arista Supervisor Module - control processor

The supervisor modules for the 7300 series run Arista Extensible Operating System (EOS) and handle all control plane and management functions of the system. One supervisor module is needed to run the system and a second can be added for stateful 1+1 redundancy. Each supervisor module takes up only a half slot resulting in very efficient use of space and a higher density design. A pulse per second clock input port enables synchronizing with an external source to improve the accuracy of network timing and monitoring tools.
