Temperature: 0°C to 40°C/32°F to 104°F
Humidity: 10% to 85% (non-condensing)
So outside the switch, temperature up to 40C are ok.
Inside an enclosed and heat producing environment temperatures are always higher then the surroundig cooler air.
With 45 inside I guess outside air (ie in the compute room) is around 25-30 degrees, which is well within limits.
I would not worry about it.
