ASR9k Fan Speed Problem

Hi,

We have an ASR9K with following chassis and cards:

ASR-9006

0/RSP0/CPU0 A9K-RSP880-SE(Active)
0/RSP1/CPU0 A9K-RSP880-SE(Standby)
0/FT0/SP ASR-9006-FAN-V2
0/FT1/SP ASR-9006-FAN-V2
0/0/CPU0 A9K-36x10GE-TR
0/1/CPU0 A9K-MOD400-TR
0/1/0 A9K-MPA-2X100GE
0/2/CPU0 A9K-48X10GE-1G-TR
0/3/CPU0 A9K-48X10GE-1G-TR
0/PS0/M0/SP PWR-3KW-AC-V2
0/PS0/M1/SP PWR-3KW-AC-V2
0/PS0/M2/SP PWR-3KW-AC-V2
0/PS0/M3/SP PWR-3KW-AC-V2

our IOS is:

6.2.3

We want to change router Fans for maintenance (one of internal fan in one fan module has problem), but when we change one or two fans we detect high router temperature.

I attached two graphs of this router. temp.png is router temperature. And fanspeed.png is router fan speed. when we change fan module, fan speed goes to 7000 rpm and temperature goes to 44 c. before changing fan module, temperature is 32 c and fan speed is 14000 rpm.

would you please tell me about our problem and how can we solve it?

 

Best Regards

Farhad

are you sure you are using correct replacement fan part compatible with router? because if there is any incompatible modules, fan module will not work. also what are the console output when you doing the task? any special warnings or errors in logs?

Please rate this and mark as solution/answer, if this resolved your issue
Good luck

This looks for me either FAN faulty again, or you may need to clean the filters
