[AMD2800]

Hi everyone,
I have a Compaq ProLiant ML350 PIII 1g. Running UNIX Sco 5.0.5 It's been runing great fro while. lucky for my since I hate when i need to touch this machine. Not very familiar with Unix. Lately the network connection get interrupted and everyone looses connection when i check the screen it said that is connected again and there is not problem but it seems like it does this once maybe twice a month and once start losing connection it keeps doing it till i reboot the server. then it work great till the next time.
I thought about getting a new board 163355-001 but I am not sure how hard is going to install this board. I assumed is not plug and play huh? any suggestions would be greatly appreciated.

Thanks,
AMD2800
