Hello
Could you let know if it is normal FAN Speed 0/FT0/* on a Cisco ASR9010 running 5.3.4.
I have two device in cluster, this device are in differente side, but I need to know of 0/FT0/* (Speed) in 9390 is normal until that change fan (because FAN 2 is 0RPM)
Can I have documentation that verificate this range?
I have searched this information but I dont have success
I checked in my device :
admin show env fans
Fan speed (rpm) and run time (in hours) :
FAN0 FAN1 FAN2 FAN3 FAN4 FAN5 FAN6 FAN7 FAN8 FAN9 FAN10 FAN11

ASR 9010 airflow is front-to-back.
Regarding fan operation on the ASR 9010:
The chassis contains two fan trays for redundancy (Figure 2-33 ). The fan trays are located one above the other below the card cage and are equipped with handles for easy removal. The chassis has a front-to-rear cooling path (Figure 2-27 ). The inlet is at the bottom front of the chassis, and the exhaust is at the upper rear.
Each fan tray has 12 fans arranged in three groups of four fans each. Two fans of each group share a fan controller. The power supplied to the fan controller is 1:3 protected. A single fan failure has no impact on air flow because the other 11 fans will compensate for it. If the fan controller fails, there is a possibility of up to two fans failing; however, the design always has two fans operating in a row (three rows of fans) to compensate for the air speed.

It doesn't address the normal fan speeds, but it does provide some detail on their operation.
