There's a fairly easy way to

There's a fairly easy way to derive the manufacture date if you happen to know the serial number. 

The serial number will be in the format: ‘LLLYYWWSSSS’; where ‘YY’ is the year of manufacture and ‘WW’ is the week of manufacture.  The date code can be found in the 4 middle digits of the serial number.  In the case of serial number SAD08300D4W, ‘08’ is the year code and ‘30’ is the week code. You can then decode the date use the following:

Here are the Manufacturing Year Codes:

                01 = 1997                              06 = 2002                              11 = 2007                              16 = 2012

                02 = 1998                              07 = 2003                              12 = 2008                              17 = 2013

                03 = 1999                              08 = 2004                              13 = 2009                              18 = 2014

                04 = 2000                              09 = 2005                              14 = 2010                              19 = 2015

                05 = 2001                              10 = 2006                              15 = 2011                              20 = 2016

 

And here are the Manufacturing Week Codes:

                1-5 : January                  15-18 : April                        28-31 : July                          41-44 : October

                6-9 : February                19-22 : May                         32-35 : August                   45-48 : November

                10-14 : March                 23-27 : June                        36-40 : September           49-52 : December

 

I hope this helps.

Re: Cisco Serial Number Lookups

   Getting the serial numbers is easy enough but you would probably have to go to cisco and give them the serial numbers to see when they were manufactured.

Would happen to know who I could contact at cisco for that?

Re: Cisco Serial Number Lookups

Try this ...

1.  Go to the Service Contract Centre:  http://www.cisco.com/warp/public/437/scc/index.html
2.  Click "Launch Tool"
3.  A window should hopefully pop up.  In the search bar, choose "Serial Number" and you enter you-know-what in the box next to it.
4.  Here's the funny bit ... If you have a result, then good.  If you don't you'll have a hyperlink to "log a support case".  I recommend this is your next step.  It takes Cisco a maximum of 4 hours to respond to your initial queries.

Hope this helps.  May I request if you can rate my post if this is helpful?  Thank you very much.

Hi sshapero!

Hi sshapero!

Thanks so much for your answer to the question.  It worked great!  I was having some problems with devices failing and they were all from the same month/year.  I was able to SSH into the other devices that I have and find the ones that might possibly have issues.

Thanks again,

Jeff
