Keysight PCIe Host Desktop Adapter Installation Guide 21Remote Chassis Power On and PCIe WakeRemote Chassis Power On and PCIe WakePCIe Wake refers to a signal placed on the PCIe link when the chassis powers-onthat turns on the host PC.Remote chassis power-on is a when the host PC turns on the chassis using thePCIe sideband CPWRON signal.PCIe Wake Generated by the ChassisThe Keysight M9010A, M9018B and M9019A PXIe chassis assert the PCIe WAKEsignal when they power on. The signal propagates through the PCIe cable to thehost PC. Whether or not the host PC powers on when receiving the WAKE signalis controlled by the PC’s BIOS and by the PCIe Host Adapter installed in the PC.Some PCIe Host Adapters have a switch setting that determines if the adapterpasses the signal on to the PC. For information about your PC’s BIOS, consultyour PCs documentation.Early versions of the M9048B and M9049A modules had this feature permanentlyenabled. To disable this feature, a resistor must be removed from the PC board;contact your local Keysight Service office. Later versions of these two moduleshave a small DIP switch. The default (from the factory) setting disable the PCIeWake feature.Some PCs BIOSs may have PCIe Wake included under the Wake onLAN (WoL) setting. If you cannot find a specific BIOS setting forPCIe Wake, try enabling/disabling the Wake on LAN feature.Figure 7 Location of PCIe Wake Switch (disabled, default setting)M9048B M9049A |
