determining manufacture year from system serial number

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

Re: determining manufacture year from system serial number

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.

Re: determining manufacture year from system serial number

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.

Re: determining manufacture year from system serial number

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.

Re: determining manufacture year from system serial number

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