[calix-nsp] Hi guys.

[Roberto Nanclares]

I have a question and hopefully somebody can help me.

 We are having problems with a customer saying that the fan trays for
his Calix C7 shelves need to be manufactured after 2005. The ones
before 2005 don't work for him.

 The problem is that I don't know how to identify the manufacturing
date of the fan trays. How can I do that if possible?

Thanks in advance.
