Normal Fan Speed for ASR 9010

[Yuliya S]

Hi guys, do you know normal fan speed for ASR 9010?

I see two various values for two my boxes with same hardware configuration:

  Fan speed (rpm) and run time (in hours) :

  FAN0 FAN1 FAN2 FAN3 FAN4 FAN5 FAN6 FAN7 FAN8 FAN9 FAN10 FAN11

0/FT0/* (Speed) 

4170 4200 4170 4110 4140 4170 4140 4200 4170 4170 4140 4140

  Fan speed (rpm) and run time (in hours) :
        FAN0    FAN1    FAN2    FAN3    FAN4    FAN5    FAN6    FAN7    FAN8    FAN9    FAN10   FAN11

0/FT0/* (Speed) 
        3540    3510    3540    3570    3510    3510    3510    3540    3510    3540    3510    3510
0/FT0/* (Run Time) 
        N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A
0/FT1/* (Speed) 
        3480    3480    3510    3540    3480    3540    3510    3510    3480    3570    3540    3540
0/FT1/* (Run Time) 
        N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A     N/A

Fan speed is dependent upon which fan trays are used in the 9010, the temperature of the router, and what the altimeter is set to. As well if you only have one fan tray inserted this will affect the speed as well as it has to do more work.

Both 9010s are within normal range.

Thanks,

Hi Sam

Is there some kind of parameter that defines which one should be the normal operation range (RPM) of the fan in ASR9010, before trigger an alarm?

Thanks in advance for your help!

Show environment table should have these values listed.

Thanks Sam, please let me to know how should I interpret the Major (Lo) threshold? the router shows 4230 as Low for Major.

R/S/I Modules Sensor                   Minor         Major           Critical 

                                                      (Lo Hi)        (Lo Hi)        (Lo Hi)

0/FT0/*
                        host Inlet0               --/--             --/ --           --/ --
                        host Hotspot0          --/ --           --/ --           --/ 86
                        host FanSpeed_0    --/10070    4230/ --      --/ --  
                        host FanSpeed_1    --/10070    4230/ --      --/ --

Thanks,

Marcelo

As long as your fans are between 4230 and 10070 the fans are in a normal operating range. How fast they spend is dependent upon the temperature of the environment / router. The fans can go above 10070 or below 4230 but that indicates an issue with the environment that should be addressed. When this happens the router will raise an alarm message.

hi.

how to check fan speed RPM range for ASR9910 ?

admin show environment table has this info.
