FMC-RK rack-mount card cage with internal power supply The FMC-RK rack-mount card cage contains 14, one-inch slots that can be populated with rack-mountable media converter units. A modular, internal power supply is provided in the rack. The unique design of the rack and power supply eliminates the possibility of a single-point failure of any module in the system from affecting the operation of the other modules.
The FMC-RK card cage employs automatic electronic current limiting within each rack-mountable module, rather than providing the current limiting within the power supply unit. In the event of a failure, only the faulty module shuts down and the operation of the other modules within the rack continue unimpaired. This automatic current limiting feature is also self-resetting, should the fault or overload be of a temporary or intermittent condition.
