Appendix B
SD Card Usage Notice
We recommend you to plug the 512 Mbytes external SD card to IPX-600. There are two very
important benefits of using the SD card:
1. The storage size of voicemail and CDR records is 10 times larger.
2. When under some terrible situation that the IPX-600 damaged, you can get a new IPX-600 in
a fastest speed and insert the old SD card into it, the whole configurations of the old IPX-600
will be back, no need to worry about any re-configuration and storage lost.
This appendix will describe the SD card behavior in more details.
Fresh SD card
- When you plug a fresh SD card into IPX-600, IPX-600 will backup all current configurations to
the SD card in the booting time.
Load Setting Sequence
- During system boot up, if the SD card is inserted and is not fresh, the system will load the
settings from the SD card; these settings will then be saved into system flash memory after
boot up. If there is no valid configuration in the SD card or the SD card is not plugged into the
system, the system will load the configurations from the system flash memory instead.
Configuration Synchronization
- During the web page configuration, when the Apply button in each page is pressed, the new
settings will be saved into the system flash memory and SD card simultaneously.
Factory Default
- When the Factory Default button in the management/upgrade page is pressed, the
configurations in system flash memory and SD card will be cleared to factory default values.
Don’t try to unplug the SD card at runtime
- IPX-600 does not support hot plug-and-unplug, so that please power off the machine before
plug/unplug the SD card into socket. Don’t unplug the SD card during system runtime.
Persistent Storage
- The CDR records and Voicemail when stored into the SD card, the storage could be
permanent.
- The CDR records and Voicemail when stored into the SD card, the storage size could be
much larger.
