The net5501 manual states:
Please note that there is limited power available for the three PCI expansion
connectors.
There are only 20W available on the 3.3V power pins and 5V pins combined.
If a 2.5” hard disk is used, it will also need to share the available power.

5A should be plenty I'd think .. but I guess it also depends on the

A few years ago I experienced issues with an ALIX board and a high power
Ubiquiti/Atheros-based mini-PCI card .. if memory serves I think it was
an XR-2 .. in that case though the miniPCI card would sort of brown ou

Yes, only I'd expect the increase in power draw to be the same when the
built-in ports fir

That's an intersting theory. I also run an external nic in the PCI
Hi Nix,
It's almost certainly a power issue as power draw for the lan card will
not be a static thing - ie will increase when transmitting packets vs idle.
Best case is that you have access to a DC-regulated power supply,
perhaps one of these -

So I just bought a lan1741 for my six-year-old net5501 (running the
latest stable Linux kernel), because four ports just isn't *enough*.
Unfortunately, it seems to not work entirely well.
Enough packet flow over any ports on the lan1741 (not necessarily tiny
packets either: a few thousand 1500-byt
