EMS device licenses
Purpose
The number of devices served by a program copy is limited by licenses for the devices.
Licensing procedure and installation
A demo license including three devices of each type for a user to evaluate the system is integrated into EMS package by default.
Eltex specialists will generate a personal root license file in the acquisition of licenses. The file should be put into the following directory:
/usr/lib/eltex-ems/conf/licence/
the demo license file should be overwritten (or deleted in advance).
As the number of licenses increases, new files are added to the same directory without root file deletion. Device licenses are aggregated across all files.
When license files have been changed, restart eltex-ems process.
If any questions corresponding license and device acquisition occur, please, contact the managers of Eltex commercial department, phone: +7 383 274-10-01, e-mail: eltex@eltex-co.ru or order a call on our website: https://eltex-co.com

Admin Panel licenses
Purpose
The number of users that can be logged in Admin Panel and work with its WEB interface simultaneously is limited by licenses.
Administrative accounts (e.g. 'admin') are not included in the total number of logged in users when new accounts are created. However, they are included there when the number of simultaneous website visitors is calculated (when entering Admin Panel).

/etc/eltex-wifi-cab/
