HP NC510C losing connection
Upon installing the NICs, Windows found a driver and installed it. I was able to configure the NICs normally and the NIC functioned fine...
.. for a short time... before the 'cable disconnected' icon appeared in the systray. The NIC's icon in the Network Connection control panel also indicates it is disconnected. Physically looking at the server, the NIC has a blinking link/activity light, and the port on the Cisco 4900M shows an active connection.
If the Network Connection is disabled then reenabled, the status goes to normal, and the NIC will communicate for a short time, before the event is repeated.
I noticed an event from NXP2NIC in the system event log which stated the driver and firmware do not match, update the driver. I updated the driver to 3.4.336.0.
The same situation occurs. After a few minutes of normal functionality, the NIC indicates the cable is disconnected, when it is not, and all physical link indicators are normal.
I'm stumped on this. Any input?

Re: HP NC510C losing connection
when Windows automatically assigns a driver to a NIC that is in fact more than just re-branded by HP, it might do so based on assumptions about the chips on the NIC that might not be 100% correct. Have a look whether HP provides a driver download for this NICs, and compare the driver in this package to what Windows uses. If it's different, I'd try that driver. Dunno how well it will run on another vendors platform, but I'd expect it to do just fine.
BTW, any "errdisable" state changes on the interfaces at the Cisco side?
HTH,
Andre.

Re: HP NC510C losing connection
It returns the following:
NetUserGetInfo:failed ,
Any switch with that command returns the same.
I'm thinking there's an incompatibility somewhere, or the driver just doesn't work.

Re: HP NC510C losing connection
The problem is the driver doesn't function properly with >32GB RAM in the system. The three servers I'm having issues with have 64GB RAM.

Re: HP NC510C losing connection
My server is a HP DL380-G5 with 16GB of memory.
Is there a driver that we can get from NetXen instead of HP? NetXen's website no longer exists after they were bought out by Qlogic.

Re: HP NC510C losing connection
once or twice a week, i get an entry in the system event log saying that "the network link is down. Check to make sure the network cable is properly connected" then one second later, the link comes back. In the teaming statistics, the CRC count has gone up and the Overruns count has gone up on one of the two adapter ports.... the other adapter port remains clean with zero errors. On the physical layer, the Cisco 6509 hasnt noticed a thing.... no errors of any kind, no disconnect..... nothing. and if I bring up the gui showing the NIC statistics on the Windows server, it says its been connected several days.... in other words, it didnt physically disconnect either. The teaming is 802.3ad LACP on both the server and the Cisco 6509. In between network disconnects, the adapter port will handle as much as 30-40 Terabytes of traffic being sent to it. The traffic is 80% backup traffic destined to the Windows server across the teamed 10Gig NICs. Anyone know what the Properties of the NC522SFP should be in a scenario like this?
