Which quad-gigabit nic for 2950 ?

Hello

I don't show that card in the part list of a 2950. It is validated for a 2970. Here is a similar card that is validated for the 2950:

D985J

Thanks

Thanks, where can I find generally , list of supported hardware per server model ?

I'm not aware of any hardware lists that are public. You can go to the support page of the server and select the parts option. You can also contact sales to see what is available. Most parts for the 2950 are likely end of life and no longer available through normal sales. The part I listed can only be purchased through spare parts. It may be available for purchase from normal sales, but I was not able to locate a part number aside from spare parts.
