Can anyone confirm whether a change was made? The switch I hear most often was previously running 10.0R4.

Sorry for hijacking your thread, but do you (or does anyone) know why the fan speed changes like this? I've noticed on EX-series, the fans go from 'spinning at normal speed' to 'spinning at high speed' on a regular schedule even when the ambient temperature hasn't significantly changed and the box isn't doing much in particular. We've got some EX2200 switches in physical spaces where the jet engine-like noise the EX4200 generates isn't desirable. Unfortunately the EX2200s make quite a racket when their fans spin at high speed as well.

[j-nsp] snmp fan bug? and are environmental thresholds configurable?
Hi, We have a bunch of mx480's running either 10.3r3 and 10.4r2 About 20 times a day the fans in these boxes switch from normal speed to intermediate speed. When this happens our nagios reports unknown status on the fans. When I do a snmpwalk of oids .1.3.6.1.4.1.2636.3.1.13.1.6.4 and .1.3.6.1.4.1.2636.3.1.13.1.6 I indeed see integer 1 (unknown) This would suggest a bug right? Or is it an old mib? In jnxOperatingState I see running and runningAtFullSpeed only, or should intermediate be reported as "running"? I cannot find a mention of this issue in the release notes of 10.3 or 10.4 Either way, do any of you have a PR about the issue? It would save a lot of time and effort if I open a case and mention a PR number. My other question is related to the env thresholds. Apparently the temperature in the facility where these boxes are located is just around the threshold where these boxes switch from normal to intermediate. Does anyone know if these thresholds are configurable? I'd like to change the threshold 2c lower.
