Abstract
An exemplary system in accordance with some embodiments includes a field-replaceable unit (FRU) and a controller. The FRU may include an FRU Ethernet coupler comprising an FRU return node and an FRU power node. The controller may include a controller Ethernet coupler including a first controller node and a second controller node. The controller may include a comparator and a switch. The controller may be operable to detect whether the FRU is connected to the controller by comparing a voltage at the first controller node to a reference voltage. The controller is also thereby operable to, when the controller Ethernet coupler is connected to the FRU Ethernet coupler with an Ethernet cable, cause current flow from a voltage source to the FRU.
