I'd like to confirm how one determines the manufacture year from a system serial number. Is the following true? I couldn't confirm this via docs on Cisco:
Do a "show version" and locate the System Serial Number.
The serial number is in this format: LLLYYWWSSSS
LLL = location of the supplier
YY = year of manufacture
WW = week of manufacture
SSSS = serial-id
Year codes:
01 = 1997
02 = 1998
03 = 1999
04 = 2000
05 = 2001
06 = 2002
07 = 2003
08 = 2004
09 = 2005
10 = 2006
11 = 2007
12 = 2008
Solved! Go to Solution.

I agree, it would make more sense for it to be a definitive value.Looking back over our records (1998 to present) across different types and, presumably, suppliers of kit, they appear to hold true as fixed values.

Hi david, I'm sure I used to have this information somewhere!
The closest I've come to finding it is this link.

You are correct apart from for the year of manufacture; your digits are correct, but it seems to define the number of years as a Cisco supplier, so presumably that could change dependent upon the supplier and the term of their relationship with Cisco, it's not very clear.
Hope this helps.

Thanks. It seems a bit odd that the number of years a company has been a Cisco supplier would be recorded versus the year the part was manufactured but maybe that's the way it was done just for those Cisco ONS 15454 line cards.

Thanks! This validates at least what I've checked against some of our own inventory.

I have some switches MDS, they start with AMS1635XXXX and AMS1650XXXX is the same for them? What is the meaning of AMS?
