Hello,
I have a question about the following show command:
RP/0/RSP0/CPU0:ASR9010(admin)#sh environment temperatures
Fri Feb 17 08:20:50.905 SCHILE
R/S/I Modules Sensor (deg C)
0/0/*
host Inlet0 33.2
host Hotspot0 42.1
0/1/*
host Inlet0 33.5
host Hotspot0 43.5
0/RSP0/*
host Inlet0 27.8
host Hotspot0 40.6
0/RSP1/*
host Inlet0 27.8
host Hotspot0 40.3
0/FT0/*
host Inlet0 26.8
host Hotspot0 28.5
0/FT1/*
host Inlet0 27.1
host Hotspot0 30.0
What temperature should be monitored?, Inlet or Hotspot?.
What is the maximum temperature that can have the router?
Regards,

Hello Jaime,
There are typically two temperature sensors per line card. Where the sensors are located varies from card to card, based on how the airflow is designed for that particular card. With the CLI command "show environment temperatures" you can read out the measured temperature from both sensors. "Inlet" is generally a sensor very near where the fans would be. On the ASR9010, this would be near the "bottom" of the chassis where the fan trays are. It's generally a spot on the card that is "upwind" of all the heat generating components. "Hotspot" is the exactly that: it's the hottest spot on the linecard and again varies a lot depending on where exactly the heat generating components are.
So better to monitor hotspots
For the threshold information you can use
admin sh envir table

Hello Vadim,
Thanks for the explanation, I understand perfectly.
In sh environment table command I can see:
RP/0/RSP0/CPU0:ASR9010(admin)#sh environment table
Fri Feb 17 08:49:49.722 SCHILE
R/S/I Modules Sensor Minor Major Critical
(Lo Hi) (Lo Hi) (Lo Hi)
0/0/*
host Inlet0 --/ -- --/ -- --/ --
host Hotspot0 --/ -- --/ -- --/ 86
That´s means that 86°C the maximum temperature that one LC could have?

Jaime Soto.

Hi Jaime,
yes, normally the thresholds are
Chassis critical ambient temperature (avg of RSPs inlet), rising ==> raise at/above 56C falling ==> clear below 54C Card critical over temperature (hotspot) rising ==> raise at/above 86C falling ==> clear below 84C Card critical over temperature shutdown (hotspot) RSP ==> at/above 93C LC ==> at/above 90C

Thanks again Vadim.
A last question:
Is there any way to the ASR sends an alarm in a more low threshold?, for example I want that when temperature is 70C the router sends an alarm.
Regards,
Jaime.

Hi Jaime,
Unfortunatelt not, these thresholds are not configurable
So the alarm will be sent when the thresholds are reached.
