I'm looking to retrieve the manufacture date on Extreme / Enterasys switches. Found this article https://gtacknowledge.extremenetworks.com/articles/Q_A/Serial-number-of-Extreme-switch-numbers-meani.... It states the first two digits are year and the 3rd/4th digits is week of manufacture along with an alpha (manufacturer) and five more digits after that.

My serial numbers have 7 digits after the first 4 digits then an alpha like A, B, E, H, J, F. Am I to assume those 7 digits after the first 4 are unique designations? Is there a document which explains the alpha at the end? Example. My serial number is 12345678901A. Looking for more details on these serial numbers.
