[VoIP] Cisco 3810

[john jones]

The physical difference are unreliable.  The outside pictures may show the part number.  A V3 version IMHO is guaranteed to have a boot prom which will recognize 16M flash ( You are correct, this is 16M not 16k) and 64M DRAM.  Unless you see a "show version" output on a pre-V3 router, you may not be able to upgrade the memory. The boot prom seems impossible to get.

Your best approach is to see the output of the show ver.  It not only shows the memory, but also the analog modules installed.  Note that the 16k of config register memory is fixed and is always 16k so no need to worry about it.

How does one identify with certainty whether a unit is a MC3810V-3, 
MC3810V or MC3810? 

Is there a reliable ID label or is it possible for a newer housing to 
contain an older circuit board? 

Are there mechanical differences that would permit reliable
 identification?

Can one rely on a sign on message at the console or is the sign on 
message generic and not indicate the version?

I assume JN meant 16MB flash.  Is this the rare case of a safe
 assumption?
