I have difficultly in understanding software packages in the IPO 500V2.
Documentation says;
Erasing the Core Software
When the firmware loaded by the control unit is erased, the control unit begins making BOOTP requests for replacement firmware files. IP Office Manager can act as a BOOTP server and respond to the control units request with the appropriate file from those installed with IP Office Manager.
What is this firmware and where it resides? Is this the same we load to the SD card?
If we follow the step above, does it erase the software in the SD card?
