FAQ-OSN3500 N3SL16A not report alarm when OSPITMPCUR value is higher board threshold working temperature

Publication Date:  2012-07-25 Views:  84 Downloads:  0
Issue Description
L1 engineer queried the board performance,found the OSPITMPCUR value was 84.9 degree,it was higher than 65 degree that is the board threshold working temperature ,but there was no temperature high alarm

Handling Process

we can use the following commands to query the threshold about optic module temperature on slot6 and slot12 board.

:optp:6,00,9b,01,30,08,c6,c6,c6,3c,3c,3c;
:optp:c,00,9b,01,30,08,c6,c6,c6,3c,3c,3c;
:optp:6,00,9b,01,08,13,01,04
:optp:c,00,9b,01,08,13,01,04
:optp:6,00,9b,01,30,08,e7,e7,e7,a5,a5,a5;
:optp:c,00,9b,01,30,08,e7,e7,e7,a5,a5,a5;

for example
:optp:6,00,9b,01,08,13,01,04
Optp cmd : 0813
01 04 04 f6 fb 00 //0x04f6 = 1270(decimalist) it shows the threshold about optic module temperature is 127 degree.
If the threshold about optic module temperature value is higher than OSPITMPCUR value,it is normal ,if the threshold about optic module temperature value is lower than OSPITMPCUR value,we can replace this board to solve this issue


Root Cause
The OSPITMPCUR shows the temperature value is not the board temperature ,it shows the optic module temperature.
Suggestions
Null
