Looking for IE4000 Architecture white paper

[RB6502]

I'm looking for a white paper or other document describing IE4000 architecture.  I poked around on Cisco.com and came up with some links to a document:Cisco IoT New Product IE4000 Switch: Part 3: Cisco IE4000 Hardware Technical Details - 25956 - The Cisco Learning Network (DOC-25956), but apparently that's no longer available.

Hello,

the IE4000 is a very simple product when it comes to HW architecture.   its not modular.

there's a central ASIC that does all the Forwarding of the Ethernet frames.  the CPU is not in the datapath.  the CPU maintains ASIC configuration.

you can't find a HW architecture diagram because, the product is pretty simple, therefore no real need for a document to show it.
