SD Card
The SD card is a core of the RAC18-IP device. The SD card contains all software elements that guarantee proper device functioning: real-time operating system and libraries.
The SD card is originally located inside the device; the SD card must be inserted into the device prior to the mounting process.
In case the device has suffered a hardware failure, it is possible to take the SD card out of the broken device and insert it into a replacement unit. In order to access the SD card in the device:
Turn the power supply off.
Discharge any static electricity by touching a known, securely grounded object.
Open the device's housing (push the device's sides to open snap fits, or use a tool as a lever, for example, a screwdriver, delicately pushing a snap fit inside).
Snap fits
Once the housing is open, locate the SD card, which is placed in the upper left corner of the device's board.
The SD card socket, installed in the RAC18-IP device, has a hinged ejecting mechanism, and it needs to be pushed slightly to the left to be opened.
Once the socket is open, pull out the SD card.
In order to insert the SD card back in the device, place it in the socket label side up, close the socket, and block it pushing it slightly to the right.
