Patent attributes
Techniques pertaining to powering multiple platforms with a minimum impact on air passage in a predefined environment are disclosed. Instead of connecting each of the platforms in a chassis to a power supply therein, the present invention uses what is referred to as cascading powering to power all platforms within minimum cable delivery. According to one embodiment of the present invention, each platform is provided with a pair of power connectors. At least one of the platforms has a power connector located towards or near a power supply so that only a short cable is needed to power the platform. The power is serially provided to an adjacent platform via a pair of corresponding connectors, each located on one of the two adjacent platforms. Such configuration is extended to the remaining platforms. As a result, all platforms are powered by the same power supply without using individual cables directly to the power supply.
