Abstract:
1. A method for cascading power supply resets, comprising: maintaining connectivity of communications signals between a first portion of a network that is upstream of a first power supply and a second portion of the network that is downstream of the first power supply; receiving power into the first power supply from a power source; converting the power from the power source with the first power supply and providing the converted power to the second portion of the network; terminating a power conductor received into the first power supply from a second power supply that is upstream of the first power supply and coupled to the first portion of the network, wherein terminating the power conductor comprises preventing supply of power from the second power supply to the second portion of the network; monitoring a voltage on the power conductor; and resetting the first power supply when the voltage on the power conductor is below a threshold for an amount of time.
