Issue Description
In slot 6, newly inserted LPUF -21 board can not register and it resets repeatedly. Logbuffer to print information is as follows.

Handling Process

Check the Dblg Diagnosis log information, we Discovery the reason of LPU6 Reset was as following .there was a CRC Error on the file which LPU obtained from the master board. Then lead to failure of the loading of the board.then the board can not register ;

The We try to replace the LPU board with a new one ,but the same fault was found . And the same information was printed;

We tried to switchover the mpu , and the same fault was found . And print information the same ;

as The two spare parts had the same fault phenomenon,  Therefore, it should not be a hardware fault;

Therefore we suspected there maybe a fault on the packet inside the MPU's cfcard; So we check the packets for the accuracy with the following command:

notes: this command including the check towards two mpu board.both master and slave

when we use the following command to check the packet in master mpu singly . there was the same error;

 

notes: this command was only including the check towards master mpu .it would print the fault in much more details.

the fault recovered after the Field engineer re-loaded the packet.

Root Cause

there was a fault on the packet inside the mpu's cfcard. during the lpu booting , it would request to download the related files form the mpu ,as it was damaged ,the LPU failed to loading. so the new lpu board failed to register ,after the new packet reloaded ,the lpu reigsterd successfully.

Solution

Back on the subject board Removing after in Fault recovery ;

Suggestions

Removing Of large packets exist in the mistakes generally condition of into introduction due to errors when part of LPUG -21 Related, and LPUG Board do not related, and equipment in no until LPUG -21 , only LPUG Board, so 一 does not affect LPUG Board running, but the effect to the newly inserted LPUG -21 Board registration. ;
