Recognise the Production Date of your Cisco Equipment based on the Serial

Today i learnt that the Production Year and Week is ‘hidden’ in the Cisco Serials 🙂

The format of the serial is always like ‘xxxYYWWxxxx’, ‘YY’ is Code for the Year, but not the Year itself! ‘WW’ is the week of manufacture.
