Product Description
The C2 incorporates two C1PS Power Supply units that provide redundancy in the unlikely event of a power supply failure. Two AC line cords (one per power supply module) are provided, allowing each supply to be connected to a separate uninterruptible power supply, providing the highest level of reliability in mission-critical applications. An audio alarm provides an aural indication in the event that one of two power supply modules has failed. The design approach employed by ComNet™ for equipment mounted within the model C2 chassis rack unit with modular C1PS power supplies, provides for the elimination of a single-point failure in the event of a major fault within any module located within the chassis rack. This is accomplished through the use of automatic electronic current limiting within each rack-mountable module, rather than providing the current limiting within the power supply unit which supports the power requirements for equipment located within the rack. In nearly all competing designs, a major fault within a module, located within the chassis rack, results in the power supply unit going into a current limiting condition, and as a result, all of the modules within the rack shut down. The C2 rack design employed by ComNet™ eliminates this possibility, as 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. Furthermore, all modules located within the chassis rack are hot-swappable, so that it is not necessary to power-down the rack when removing or replacing modules.
