Hi Samir
Following is my understanding on OD2s.
https://meraki.cisco.com/lib/pdf/eol/meraki_eol_od2.pdf
Excerpts from the above Url says OD2s
• End-of-Sales Announcement: July 26th, 2012
• End-of-Sales Date: October 30th, 2012
• End-of-Support Date: October 30th, 2017
I understand you may be able to use OD2s without License if you have not upgraded your Pro Dashboard to Enterprise Dashboard. Also Pro Dashboard is not available any more.
If you create a new Dashboard that shall be Enterprise and one needs to purchase License to use the Access Points.
Having said that I shall recommend reaching Cisco Meraki Support for better understanding.
Regards,
Ajit
