| 6000-S4001134 | T:LAN | Adds Supplemental Log Entry To T:LAN EVENT LOG To Distinguish Between Actual NVCM Issues And ‘RAM:FILE Re-Initialized’ Entries Caused By User Performing Diagnostic RTC Tests Using The NPA Command $ADBC3243. Real RAM:FILE (NVCM) Issues Will Be Listed As A Single ‘RAM:FILE Re-Initialized’ Entry In The Log. User Initiated Diagnostic RTC Tests Will Show The ‘RAM:FILE/Battery Testing’ Entry Right Next To The ‘RAM:FILE Re-Initialized’ Message As The RTC Tests Are Invasive And Require The Restoration Of the NVCM Contents After Each Test. | |

OPTIMA RECOMMENDATIONS
Perform T:LAN OS Update To A Level Above BN7655
T:LAN OS Versions prior to BN7655 contain a pre-calculated table to determine the DST Start and DST End dates (North America/Canada DST Rules). To guarantee proper DST adherence, Optima recommends that all customers upgrade the T:LAN firmware running in their production units before the current table based data reaches its end. The table based method will provide reliable service until 2026. The new algorithm based method to determine the DST start and end dates helps extend the service life of a T:LAN unit until at least 2037.
Perform T:LAN OS Update To BN7798
Optima recommends that all T:LAN units that have been in production networks for close to 20 years (or more) be regularly checked for the presence of the ‘RAM:FILE Re-Initialized’ and/or ‘RTC Battery Failed’ entries in the T:LAN EVENT LOG.
T:LANs are equipped with a lithium battery on its main printed circuit board. The battery offers a data retention span of nine years (with the unit powered down) and has a total life expectancy of more than 20 years (powered unit). A reliable retention of the T:LAN configuration settings cannot be assumed once the battery is spent. Depleted batteries must be replaced. Please refer to “T:LAN Battery Replacement Procedure” in the T:LAN USER GUIDE for instructions on how to properly and safely replace the lithium battery.
Customers are also encouraged to update to BN7798 before performing the proactive maintenance step [N]PA $ADBC3243 in order to fully test the RTC battery.
