Working Principle
Every license key is a unique key for one and only one option or device type up-
grade or software option, coded with a serial number.
During system startup, the operating software reads the EEproms to check the en-
abled hardware options and to check the device type. The read device type leads
to a filter within the hardware access level of the operating software to ensure that
only the dedicated M/E are controllable by the user.
The software licenses are stored within a file license.txt and the built-in license
manager will check and verify the valid license key codes once per day and if the
code is invalid or terminated, the license manager will kill the software option mo-
dule during runtime. Software options may be enabled temporarily (start time, end
time).
For each ordered license, the manufacturer creates a license code which is entered
prior to delivery to the customer, thus enabling the option. Furthermore, a license
document is provided with all required information and is added to the documenta-
tion for the customer.
Please note that the key code is indicated only in this License Document –
keep it save!
When placing a special order for software options only, the license document of the
indicated switcher is created and send to the customer together with the complete
System CD-ROM. For creating the license key, the customer has to inform the
manufacturer about the serial number of the respective subassembly.
The respective serial numbers are contained in the Diagnose menu when selecting
the mainframe host.
