Regarding danger temperature zone

I’m writing to about temperature issue.
The thing is, High temperatures are dangerous.
But, I don't know danger temperature zone.
Hence, Is there the cisco set up a standard about the temperature value?

for example, 70oc -> critical, 100oc -> need to rma

plesae refer to below log.
module 9 asic-1 temperature: 63C module 9 asic-2 temperature: 59C

"show environment alarm

"show environment alarm thresholds module 9" should show you the minor and major threshold values for the temperature sensors on that line card

thats the temp specification

thats the temp specification the room should be running in between to have the device operating normally at proper temps , where the device is stored basically , these are recommendations , you will see nearly all data sheets have a max of 70 degrees but then can vary how cold the room can be too some as low as 40 or 20

Hi

Hi

if you check your modules data sheet online you will see they have guidelines for the temp to be ran at , 63 is high you may need more air conditioning in room /ventilation

Diff modules can vary though so always best to check the sheet for esach type but generally you want to be below 50%

As an example I just checked a few 6500s I have here and there all below 50% and within the range expected for my module 6748

module 2:
  module 2 power-output-fail: OK
  module 2 outlet temperature: 34C
  module 2 inlet temperature: 30C
  module 2 device-1 temperature: 34C
  module 2 device-2 temperature: 31C
module 3:
  module 3 power-output-fail: OK
  module 3 outlet temperature: 38C
  module 3 inlet temperature: 26C
module 4:
  module 4 power-output-fail: OK
  module 4 outlet temperature: 32C
  module 4 inlet temperature: 28C
  module 4 device-1 temperature: 37C
  module 4 device-2 temperature: 29C
module 5:
  module 5 power-output-fail: OK
  module 5 outlet temperature: 33C
  module 5 inlet temperature: 29C
  module 5 device-1 temperature: 38C
  module 5 device-2 temperature: 31C
module 7:
  module 7 power-output-fail: OK
  module 7 outlet temperature: 29C
  module 7 inlet temperature: 24C
  module 7 device-1 temperature: 32C
  module 7 device-2 temperature: 33C
  module 7 asic-1 temperature: 25C
  module 7 asic-2 temperature: 25C
  module 7 asic-3 temperature: 25C
  module 7 asic-4 temperature: 25C
  module 7 asic-5 temperature: 25C
  module 7 asic-6 temperature: 25C

Environmental Conditions

   Operating temperature: 32 to 104°F (0 to 40°C)

   Storage temperature: –40 to 167°F (–40 to 75°C)

   Relative humidity: 10 to 90 percent, noncondensing

   Operating altitude: –197 to 9843 ft (–60 to 3000m)

Thank you for your reply.

Thank you for your reply.

If this issue is unrelated to aircon, What should i check?  (this means that air condition has already installed)

VIP Purple

Make sure none of the rack

Make sure none of the rack panels where the fans are on the chassis are obstructing the airflow if the temp in the room is ok or that no other device is blocking airflow

Make sure no other devices are seeing same issue that way it will isolate it to just the chassis , turn up the aircon if possible  see if it makes a difference over a day

Thank you for your assistance

Thank you for your assistance.

I have a last question..

As I know, Operating temperature means that equipment is working normally. Then What do you mean by "Storage temperature"
