Today I installed the 15.1R6.7 on my EX2200-C at home – this Release fixed one of the most annoying Bugs –> The Temp-Sensors are now “seen” again and the red-alert is gone.

By setting GEPHY1 to 0 degrees C the Alarm has no intention to cry – and finally my Juniper-Rack is green again – thanks Juniper 🙂

In the next days I will lab some more with this release – I expect it to be “recommended” ASAP by Juniper because 99% of our Customers didn’t move from 12 to 15 due to this nasty optical bug. Of course there are also some problems with dot1x in 15.1R5 but that’s a different story 😉
