I have installed an Intel PRO/1000 MT Dual NIC into an HP Elite 8200 box on which I'm running Citrix Xenserver 6. The HP box also has an onboard NIC which works fine.
I'm having problems with the dual NIC. If I plug a cable into one or the other, but not both at the same time) that NIC lights up and shows as connected in the XenServer console. But as soon as I plug a cable into both NICs neither of them lights up and XenServer seems to lose sight of both of them.
Why can't both work simultaneously? Do I need to run an Intel utility of some sort on them to configure/flash them in a certain way for a Linux box (XenServer is based on Red Hat)?
I have also tried getting them both to work when booting into a Linux Live CD so I don't think it's a XenServer problem. I have also found that the exact same problem exists when the dual NIC card is installed in a Windows 7 system - one of the NICs will work, but as soon as you plug a cable into both the lights go out. So it doesn't seem to be an operating system issue.
