inrow cooling : tempreature sensor fault

[BillP]

Hi guys

we install 24 RC301s in one of our customer site. but 2 of them have rack temperature sensor fault . we uninstall it and install it again and the error was disappear.but after a while the fault is apear again. i changed the sensors,but still have problem . any help or idea ?

Hello Seyed. Is the rack inlet sensor reading a temperature when it is in fault or does it say err? Do we have any other sensors (temperature or leak) connected up to this unit or is it just this one rack inlet sensor? There are four places where that sensor can be plugged into the board. Have you tried all four spots?

Thank you

No , it does not read any temperature when goes to fault . each device has a leak sensor and i try all four spot for connecting temp sensor. is it any chance to for received noise from this sensor ? because this inrow is behind of PDPM racks?

 please check in unit status which sensor is faulty shows like (Err) instead of gives temp value. just replace that sensor hopefully after that cooling unit will working fine .unit status show every sensor status.

Hello. Can you take this sensor and move it to a unit that is not throwing a sensor error and also take the sensor from the good unit and put it in this unit to see if the fault follows the sensor or stays with the unit?

Thank you
