Customer reported TEM_HA alarm on one of the STM64 board in OSN7500. Site engineer visited the site for inspection and found high temperature in room
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
After analysis N1SL64 board's SFP module on input port was over heated due to high temperature in room.
Always make sure that room temperature is in the best range to avoid any heat up situations of equipments.
