SD Card
You can order a PLX3x gateway with an optional SD card (Part Number SDI-1G).
In the event of a module failure, you can move the SD card from one module to
the next and resume operation.
In general, if the SD card is present when you power up or reboot the module,
the module uses the configuration on the SC card.
With an SD Card
PCB downloads the configuration to the SD Card in the module.
The module does not transfer the configuration data from the SD card to
internal memory. If you remove the SD card and reboot to the module, the
module loads the configuration data from the module’s memory. If there is no
configur
ation data in the module’s memory, the module uses the factory
default configuration.
Without an SD Card
PCB downloads the configuration to the
module’s internal memory.
If you insert a blank SD Card into the module after the module has been
configured, the module does not use the configuration on the SD card unless
you reboot the module. If you want to copy the configuration to the SD card,
you must download the configuration while the SD card is in the module.

Connecting Power to the Unit
WARNING: Be sure not to reverse polarity when applying power to the gateway. This causes
permanent damage to the gateway’s internal power distribution circuits.
