[j-nsp] ACX7100-48L

[Aaron Gould]

I might be hitting PR1664302

keep in mind, I have another 7100 racked right beside this one with no 
problems

me at lab-7100-2> show log messages | grep "cooling|shutdown"
...
Jun  8 20:23:23  eng-lab-7100-2 hwdre: HWD_COOLING_FIRE_SHUTDOWN_INIT: 
Cooling zone fire action initiated !!
Jun  8 20:23:23  eng-lab-7100-2 hwdre: HWD_COOLING_FIRE_SHUTDOWN_SENSOR: 
Sensor /Chassis[0]/Fpc[0] Sensor J2 Max Reading crossed fire threshold 
temp value 136, driving chassis to shutdown

but i just now had someone pull the power cords since i couldn't console 
in... so I don't know if this reboot reason is from the power cord pull 
or the previous high temp shutdown PR condition

me at lab-7100-2> show chassis routing-engine | grep reboot
     Last reboot reason             power cycle

interestingly, the PR is said to be fixed in 22.2R2-EVO, wouldn't that 
follow that it should be fixed in my version? 22.2R3.13-EVO

me at lab-7100-2> show version
...
Junos: 22.2R3.13-EVO
