Lindy LF1TBELRG User Manual

The upgrade program rewrites the LINDY CPU Switch Smart’s firmware code. If the 

upgrade process is interrupted then the LINDY CPU Switch Smart will have invalid 

code and will not be able to operate. It is therefore good practice to ensure that the 

upgrade process is always fully completed. A partial or failed upgrade may be 

rectified by performing another upgrade. If the upgrade process is interrupted 

accidentally then you should immediately repeat the upgrade process without 

moving switch 7 from the flash upgrade (ON) position. Switch 7 forces the LINDY 

CPU Switch Smart into flash upgrade mode and prevents the upgraded code from 

being run. Running faulty or partially upgraded code may have unpredictable results 

and may damage your LINDY CPU Switch Smart or computing equipment. For 

obvious reasons, the code that the LINDY CPU Switch Smart uses to perform 

upgrades is not itself upgradeable - a common problem on some flash upgradeable 

products that could effectively be destroyed by a partial upgrade!
