Abstract
An approach is provided in which a host system receives a request to power down a selected I/O module located in a PCIe I/O expansion drawer. The host system identifies at least one cable card located in the host system that corresponds to the selected I/O module and transmits at least one set of sideband signals to the PCIe I/O expansion drawer through at least one set of PCIe cable links. The host system, in turn, inhibits the transmission of the at least one set of sideband signals to power down the selected I/O module.
