5525-X Fan speed slow ?

[sdawson35]

Hi,  We have multiple ASA 5525-X firewalls however one reports the fans running at 5300 rpm and a status of okay all our other 5525's report a fan speed of 6144.

The unit reporting 5300 rpm is running 8.6.(1)2, and the others are running 9.8.(2)17.

I have not found  a bug report for 8.6 and fan speed reporting issues so what could the problem be ?

If believe the OK stands for the fan health, not for the speed.

Fan speed changes based on the temperature.

To check if the temperature is ok you can use: show environment temperature
