Publication Date:  2012-07-25 Views:  48 Downloads:  0
Issue Description
OSN1500 CXL  boards temperature is very high. T2000 SDH Performance Monitor reports 82 C, but TEMP_OVER alarm is not reported for this board.
Alarm Information
Null
Handling Process
1. Use command :cfg-get-bdtemp to obtain XC board temperature, that could trigger TEMP_OVER alarm, the real temperature of the board obtained thru this command was 62 C. 
2. Use :cfg-get-bdtempth to obtain XC board temperature threshold, that used for TEMP_OVER alarm generating. The default thrshold set to 65 C. 
3. To check alarm generating mechanism OK or not the threshold had been set to 60 degrees instead of 65, the CXL board reported TEMP_OVER alarm then.
Root Cause
The SDH Performance displays optical ports (laser) temperatures of CXL boards, but not the board temperature. The types of working temperature that can be queried vary with board types. The laser temperature does not trigger TEMP_OVER alarm. 
Suggestions
Null
