OSN3500 MD12 Boards report TEMP_OVER alarm due to software bug

Publication Date:  2012-07-25 Views:  34 Downloads:  0
Issue Description
OSN3500 MD12 boards report TEMP_OVER alarm, the alarm clears by itself but appears again after some time. Cold reset MD12 cards and PEG8 cards, the problem still exsit.

SCC Version is 5.21.31.35.




Alarm Information

TEMP_OVER

Handling Process
Upgrade the version of PEG8 to 1.52 and its later versions to solve this problem, and please pay attention that board software should keep consistent with SCC version.


Root Cause
1, The software of N1MD12 board is running on the N1PEG8 board, so we check the software version of PEG8 board using the following command (:sftm-get-testver:bid), we find that the software is 1.51.

2, We recur this problem in lab, when the software version of PEG8 is 1.51, then the MD12 will report TEMP_OVER alarm, this is a software bug, and has been solved at the version of 1.52.


 

Suggestions
If the version of PEG8 board is 1.51, and all the MD12 boards on the NE report TEMP_OVER alarm, the alarm clears by itself but appears again after some time, please refer to this case. For this case,  PEG8 board version is 1.51, this version also does not match with SCC version (5.21.31.35), the right version is 1.52.
