Will a 450 5 GHz AP running ver 12.2 that fails to reboot due to cold temp problem work once again after it warms up if left unpowered until then or is it a brick that must be replaced now? Had one get power cycled last night while changing out a UPS and the temp is 26 degrees F.
It should come back to life once warm… however, we have seen cases where certain units are non-functional even at room temperature. If you can get it warm, and get it to boot up, it’s recommended to immediately upgrade to R12.2.2.
Please upgrade ALL of your radios to R12.2.2 as soon as possible to eliminate the issue.
If you are unsuccessful in getting that one to boot, please contact tech support
