====== MicroSD Card ======

A micro SD card is included in the following devices:

  * 52/XC Cores (52-740xC or later), 
  * 52/XC2 Cores,
  * 52/XD Cores, 
  * 52/XD2 Cores,
  * 52/XS Cores (52-180xC or later)
  * 52/XS2 Cores

[{{ :licensing:maintenance_serial_number_microsd_card.png?400|//Maintenance window showing the Serial Number (Sxxxxxxxxx) that is required for licensing//}}]**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.
<WRAP center round info 60%>
**Note**\\  
It could happen that the microSD serial number appears as a negative value with format **S-xxxxxxxxx** in the Maintenance window. This is caused by an error on the Maintenace webpage - the microSD card itself is not affected! \\ This issue **"Maintenance Page: MicroSD Card Serial Number could appear as negative value"** is fixed since the following firmware versions:
  * 8.1.44
  * 8.2.8
A firmware update is recommended in this case.

All available software licenses and feature upgrade licenses are stored on the microSD card. This includes the following licenses:

52-8511 - PC TFT View Software\\ 52-8550 - Routing/Scheduling Software\\ 52-8551 - Routing Software\\ 52-8552 - Routing Software, single matrix\\ 52-8553 - Additional license for 52-8550\\ 52-8554 - Additional license for 52-8551\\ 52-8555 - Monitoring Software\\ 52-8562 - Snapshot Manager Software\\ 52-8563 - Remote Control Software\\ 52-8564 - Remote Control Software, float.\\ 52-8565 - DSP Control Software\\ 52-8566 - DSP Control Software, float.\\ 52-8571 - Pro-Bel Protocol SW-P-02\\ 52-8572 - ESAM-II control protocol\\ 52-8575 - MIDI Protocol Converter Software\\ 52-8581 - Enhanced DSP Processing\\ 52-8582 - XC/XS Core Audio Network\\ 52-8583 - XC/XS Core Control Networking\\ 52-8584 - XC2 Core Gold upgrade\\ 52-8585 - XC2 Core Silver upgrade\\ 52-8591 - SNMP Support for DHDOS


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.

**Note**\\  Only the microSD cards delivered by DHD can be used.
</WRAP>

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.

<WRAP center round alert 80%>
**Warning**\\  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.
