The CWCHASSIS is supplied with a single power supply but can also be fitted with a second power supply (sold separately) that provides redundancy in the unlikely event of a power supply failure. LED indicators provide visual indication in the event that one of the two power supply modules has failed. The design approach employed by ComNet for equipment mounted within the CWCHASSIS chassis rack unit with two modular CWCHASSISPSU 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. 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.
