Currently, we are running this:
Cisco 7206VXR (NPE300) processor (revision D) with 122880K/40960K bytes of memory.
Processor board ID 18278379
R7000 CPU at 262MHz, Implementation 39, Rev 1.0, 256KB L2 Cache
6 slot VXR midplane, Version 2.1
The question: will the midplane version handle the NPE-G1 and where is the documentation?
