Cisco switch temperature alert for C9500-24Y4C

[user1981]

Dear all,

we have C9500-24Y4C Datacenter switch which is about 1 year old. Lately we are getting following alert from the switch;

Temp: Outlet_B   R0                Normal            40 Celsius

Temp: Inlet_A    R0                Minor             46 Celsius

Temp: Inlet_B    R0                Normal            43 Celsius

We have managed our datacenter at 20 degree temperature even though inlet A is showing a bit high temperature. what might be the cause? please suggest.

Hi,

We have managed our datacenter at 20 degree temperature even though inlet A is showing a bit high temperature. what might be the cause? please suggest.

The 20 degree that you are referring to is the room temperature and not the device itself. Depending on the rack mount type, the rack or cabinet type you have installed, the device temperature can be within 5 to 10 degrees higher than the room. If you want to lower the temperature on the device then you would have to lower the temperature for the room and keep an eye on it for a while to make the device temperature also change.

Hi, i have the same issue too. other devices in the same rack show 15 degree less inlet temperature. Also the outlet temperature is lower then the inlet temperature like show here in the first post.

Dear all,

we have one C9500-48Y4C and the same problem. The inlet temperature from sensor A is higher than the outlet temperatur. Instead of sensor B, there is all normal:

R0 Temp: Outlet_A Normal 42 Celsius (55 ,60 ,65 ,75 )(Celsius)
R0 Temp: Outlet_B Normal 37 Celsius (60 ,65 ,70 ,80 )(Celsius)
R0 Temp: Inlet_A Minor 45 Celsius (45 ,55 ,65 ,70 )(Celsius)
R0 Temp: Inlet_B Normal 37 Celsius (55 ,65 ,75 ,80 )(Celsius)

The Switch is in a normal rack and and only a few ports are in use (16 from the 48 Twe and 2 from the four Hu). There should also all inlets be open for good air flow and no impact.

An other switch (2960X) in the same rack, has no problems.

I see also now a Bug for this:
