CRS317-1G-16S+ fans not stopping

Mon Apr 02, 2018 10:54 pm

After temperature went down to +32-34 CRS317-1G-16S+ isn't stopping fans. Is it normal? Is it possible to stop them?

I've observed this also a couple of times after 2-3 weeks of uptime. Then the fans seem to keep their last state (RPM) and even when the temperature is below 40C they don't stop anymore.
I already opened a ticket once and they first suspected a hardware issue, but as the fans start to bahave well again after a simple reload this seems not to be the case.
Looking on the other issues noted in the forum, I guess CRS3xx is still a to fresh platform to expect no teething troubles ;)

Well, spring is coming. In LA it's not that hot, but already can hits 30 in Celsius. During summer time I believe fans won't stop even when it will be fixed. So, developers have some time to fix it. :D

What if the fans are stuck in low RPM state and the box heats up too much if it's not able to control the fans anymore? Maybe this bug can be triggered while the fans are off...

Upgraded software version up to 6.42rc52 to get HW Offload for LAGs. Surprisingly found out that fans working quietly. Speed fluctuating for about +/- 100 RPM. When temperature goes down and gets lower than 39 fans are stopping.
