ComNet C2: Rack Mount Card Cage With Redundant Power Supply

ComNet C2: Rack Mount Card Cage With Redundant Power Supply

Product Code: CN-C2*


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 two 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 achieved by 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.
