Cisco Switch Model is cisco WS-C3750G-24PS (PowerPC405).
Following is the log of this switch. So anybody helps me to understand this?

%HARDWARE-2-THERMAL_WARNING: Temperature has reached warning threshold

if you worried about this logs, look at below explanation and required further information what is the device connected along with controller information.
