and I have an L2 controller and a router brick, power module and all the cables, etc..
I have put it together as per the tech pubs document...

I have a router brick not an Origin 300 NUMA link brick
This is likely to cause my biggest headaches:
a) The Router Brick/NumaLink Modules are reported to be the hardest to overcome the serial security issue <not withstanding the claim of one member - for which he can't or won't provide detail>
b) SGI probably used a NumaLink Module <rather than an O3k Router brick> for a reason. I'm aware that that reason could have solely been for marketing purposes, but this snippet from the PCI Module manual might offer a hint:
TechPubs wrote: The SGI 300 compute module cannot connect to a P-brick because the P-brick requires a connection to the I/O interface (II) of a Bedrock ASIC. The I/O interface of the SGI 300 compute module's Bedrock ASIC connects to an internal Xbridge ASIC.
In order to expand the I/O capabilities of the SGI 300 compute module, the network interface (NI) of the SGI 300 compute module's Bedrock ASIC is used. This interface must connect to another NI port; therefore, it must connect to a device that has a Bedrock ASIC. The PCI expansion module has a Bedrock interface card (BIC) that contains a Bedrock ASIC. (The P-brick does not contain a Bedrock ASIC.)
This Bedrock-to-Bedrock communication is referred to as peer I/O. The PCI expansion module is a “peer” I/O device to the SGI 300 compute module. In other words, the SGI 300 compute module communicates with the PCI expansion module in the same manner that it would communicate with another SGI 300 compute module.
So does the Numalink module also use peer-to-peer topology and the O3k Router not?
None of this is well documented and anyone who has achieved this has kept it secret.
I started a wiki topic

I have sent PMs to various people and the response I have gotten back have been terse and opaque, which kind makes want to dump it all in land fill and move somewhere rural overseas.
