Change Air Flow

troy_alan — Tue, 05 Jul 2022 18:49:45 GMT

I replaced the all fans and power supplies in two switches to convert them f2b to b2f airflow. Now both switches have "Code 5: Air flow mismatch detected in slot 1" warnings.

I assume rebooting the switches will fix this but is there a command that I can run to avoid rebooting them?

Hi Roy,

Can you provide the output of "show fan detail" and "show power detail"?

Thanks,
Chris Thompson

There still looks to be a mismatch as 2146N-40897(17116) is back to front and 1912N-40192(17115) is front to back.

I think Fan 6 is also back to front as well.

Thanks,
