Bulk Erase Configuration Memory
The bulk erase function can be used for the following purposes:
• Erase all configuration and cardholder database (sanitize board, less third party applications)
• Update OEM default parameters after OEM code has been changed
• Recover from database corruption causing LNL-X4420 board to continuously reboot
If clearing the memory does not correct the initialization problem, contact LenelS2 OnGuard Technical Support.
Bulk Erase Steps
Important: Do not remove power during steps 1-6.
1. Set S1 DIP switches: 1 & 2 "ON" and 3 & 4 "OFF."
2. Apply power to the LNL-X4420 board. LED 1 on for about 15 seconds while LNL-X4420 boots up.
3. After the LNL-X4420 boots up, watch for LEDs 1 & 2 and 3 & 4 to alternately flash at a 0.5 second rate.
4. Within 10 seconds after the above pattern starts, change switches 1 or 2 to "OFF." If these switches are not
changed, the LNL-X4420 board will power up using the OEM default communication parameters.
5. LED 2 will flash indicating that the configuration memory is being erased. Full memory erase takes up to 60
seconds, usually a lot less.
When complete, only LEDs 1 & 4 will flash for about 3 seconds.
6. The LNL-X4420 board will complete its initialization in 2 seconds after LEDs 1 & 4 stop flashing.
