Disagree. It’s somebody’s job somewhere to have this data on-hand. You just have to find them.

I've been looking through everything we have (including the CDROMs from 2002-2003) but the main issue is that the publication numbers listed for the physical manual they need (03-4200) is quite different than the publication numbers for all of our stuff. Everything we have uses a publication number like 297-3601-450, so it's possible that installation manual is a separate, special manual you/the company installing the switch would have for the initial physical install and the rest of the publications assume you already have an installed DMS-10.

There's a chance we never even had that manual ourselves, if that's the case! I did find our original installation proposal documents - our DMS-10 was installed in 1989/1990 :)

Yeah, thats the rub, it would have been held by the Nortel Installers.

Do you have a copy of 297-3401-000?

Edit - I think the document we're looking for is IM 03-4200

Assuming the number is correct - the Installation Method documents appear to be NN-NNNN rather than NNN-NNNN-NNN

I did find some IM papers, I can look through them again tomorrow and see what I can turn up.
