MicroSD Card
A micro SD card is included in the following device:
- 52/XC3 Cores
The 52/XD3 Core is using an SSD drive for storage.
This card acts as a dongle and the licenses stored on the microSD card are bound to the internally stored serial number (Sxxxxxxxxx) of this microSD card. The SNxxxxx number printed on the hologram label (hologram reference number) is only required in case of a microSD card failure to restore the licenses.
Since Firmware version 10.0 checking licenses is done via WebApps
The microSD card also includes the firmware, the configuration and snapshots of this core device.
In case of a replacement of the core device, it is only required to put the microSD card from the installed device to the replacement device (which has to be the same device type as the device that will be replaced). When the replaced core device will be switched on, it will boot with the last configuration state as the first device.
Only the microSD cards delivered by DHD can be used.
It is possible to copy the content of the microSD card, but the licenses will not work on this copy because they depend on the internal unique serial number of the microSD card.
In case of a microSD card failure, the microSD card needs to be returned to DHD! Do NOT throw away the microSD card! Do NOT remove the hologram label with the hologram reference number (SNxxxxx)! In the event of loss of the microSD card, the licenses will not be replaced.
