Statement of Volatility
Clearing user and site-specific data from a LinkRunner AT Tester
The LinkRunner AT incorporates volatile and non-volatile memory. Volatile memory is memory whose contents are lost when power is removed. Non-volatile memory is memory whose contents are retained when power is removed. Both memory types can be sanitized to remove user and site-specific data previously stored in memory. The sanitation processes for each memory type are provided below.
Volatile Memory
Memory type | Size | User modifiable | Function | Process to sanitize |
SRAM | 608KB | Yes | Program data and stacks | Turn off power for at least 60 seconds. Battery removal is not required. |
SRAM | 1MB | Not directly | Frame buffer for packets received from the network | Turn off power for at least 60 seconds. Battery removal is not required. |
Non-Volatile Memory
Memory type | Size | User modifiable | Function | Process to sanitize |
Program Memory | 3 MB | No | This is the LinkRunner executable program code | No user data stored. The program code is updated/re-flashed using LinkRunner Manager. |
Factory Programmed | 4KB | No | Instrument Serial Number and MAC address | No user data stored. This information is programmed into the unit once in the factory. |
EEPROM | 128KB | Yes | Storage of user profiles and reports | Clear the current settings using Tools > Restore Factory Default. |
Note: The time of day clock is a separate chip which contains only time and date information. It can be cleared by removing the main battery for at least 2 hours.
