Control Board Overview
Inspect the Control Boards to ensure that control and monitoring functions occur for the
router.
The Control Board works with an adjacent Routing Engine in the host subsystem on M120,
M320, T320, T640, T1600, TX Matrix, and TX Matrix Plus routers to provide control and
monitoring functions. These functions include determining Routing Engine mastership,
controlling power, performing reset and SONET clocking for the other router components,
monitoring and controlling fan speed, and monitoring system status using I²C controllers.
