Referring to
 Will a 'Series 1" option module work in a 140/180-Class S-Series I/O Module or Fabric Module?



Never heard of cards referred to as Series 1 and Series 2.  They are normally referred to as Type 1 and Type 2     A Type 1 card can be installed in a 140/180 class blade.

Hi Curtis, 

I checked the document and you are right. The option modules are normally referred to as Type 1 rather than series 1 used there. For the sake of consistency i will change that document to be in line with normal terminology

Unfortunately many cases are being generalized for knowledge base articles  so much that they either become unhelpful or wrong.  In this case even the specific case described is wrong according to extreme documentation.   In practice  we have at least one Type1 card running in a 140 or 180 class blade.

I see what has happened in this case. It is not as simplistic as type 1 or type 2 modules. There are earlier versions of some modules that require a specific serial number range to be compatible with later blades. I will get an article created that covers the scenarios fully.

Hi Curtis, 

Firstly, thanks for bringing to our attention the need for evolve content to clearly explain all the different option modules, types and compatibility. I have written an article that i think will be helpful. I think the origianl article that you highlighted was correct but i agree that it could have been clearer since there is some distinction of terms needed. Please take a look at the article below and let me know what you think to it. I hope it is a good central reference for all thing option module and has links out to other articles where appropriate.

Thank you!  That is a much better and informative article.    I am much less confused about series, types, revisions, etc.  I know GTAC is  writing these in their "spare time" between calls so they do not have the time to do  the level of research and writing  it took to generate your article.             If I may make a suggestion, move the note at the bottom about the series 1 serial numbers up to the Series 1 section.

So i just did a few minor edtis, moved the series 1 serial number section as i agree it works better up there and added  a section on how to determine type from part number as well. I also just wanted to let you know that there is a feedback section at the bottom of each article that you can use to communicate with us on specific articles, good or bad , we need to hear both. These are closely monitored and actioned. 

Thanks
Glyn
