Alarm Information

TEM_HA

Handling Process

First of all the room tempeture was reduced upto the normal range. Then N1SL64 board was pulled out for 5mins so that the tempeture of board and SFP module is cooled down. This is dangerous situation in which board hardware may get faulty

Root Cause

After analysis N1SL64 board's SFP module on input port was over heated due to high temperature in room. 

Suggestions

Always make sure that room temperature is in the best range to avoid any heat up situations of equipments.
