When disabling unconnected network ports in Windows 2008 / 2008R2 running on X4170M2 or X4270 M2 hardware you may see a number of correctable WHEA events being logged in the Windows System event logs.
This may also lead to uncorrectable WHEA events under heavy network load which will trigger a Windows Blue Screen of Death (BSOD) crash of type WHEA_UNCORRECTABLE_ERROR(124) causing the system to unexpectedly reset.
