Hi,
With the NPE-G1 the I/O controller has its own PCI bus so with that
installed it show slike this:
PCI bus mb1 (Slots 1, 3 and 5) has a capacity of 600 bandwidth points.
Current configuration on bus mb1 has a total of 0 bandwidth points.
This configuration is within the PCI bus capacity and is supported.
PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points.
Current configuration on bus mb2 has a total of 400 bandwidth points.
This configuration is within the PCI bus capacity and is supported.
Thanks for the offlist replies everyone, it looks like the back plane is
going to be the limiting factor in this device due to the 1gbps total
capacity [1].
