5 beeps & falsing power LED after Installing a Broadcom dual network card into my dc7800

dc7800
Linux

If I install a Broadcom BCM 95720A dual gigabit network adapter card into either of the PCI-e x1 slots on my dc7800 SFF, the power LED flashes continuously and there are 5 beeps which repeat 5 times and then stop. At this point the PSU fan speeds up to macimum speed and the system won't boot nor is there anything on the screen. I have tried removing all other option cards from the system but it's obviously the Broadcom NIC that's causing this. I've tried 3 different cards and both of the PCI-e x1 slots.

 

What is the cause of this and if the BCM 95720A is not supported in thsi system, what other dual gigabit NICs are comptaible with this system? (Note I can't use the PCI-e x16 slot since I normally have a graphics card in it).

 

Thanks in advance for any suggestions,

Andy

Hi

 

1 low profile PCI, 2 low profile PCI Express x1, 1 low profile PCI Express x16 (standard),

2 full-height PCI slots (available via optional riser card)

Well this doesn't really answer my question of why the Broadcom PCI-e x1 network card doesn't work in this system.  Also, fitting the optional PCI riser kit means getting PCI bus adapters for my dc7800 SFF and I would then lose the PCI-e x16 slot which I use for graphics. But the Broadcom card works OK in a dc7900 SFF (and so do Intel quad port low profile NICs) so switching to one of these systems is my best option.

 

Thanks for the suggestion but I think the dc7800 SFF isn't the best choice for what I wanted to do whereas the dc 7900 SFF is.
