Hello,
I find that our computer room is quite warm but I am not sure the temperature is suitable for our equipement. I ran a "sh env temp" on our catalyst 6500, but I can't quite now how to interpret these values. Documents I found show the operational temp for a cat6500 is between 0 and 40C, but which of the values in the sh env will tell me the if the temperature is OK or not:
sh env temp
VTT 1 outlet temperature: 31C
VTT 2 outlet temperature: 51C
VTT 3 outlet temperature: 33C
module 1 outlet temperature: 37C
module 1 inlet temperature: 28C
module 1 device-1 temperature: 28C
module 1 device-2 temperature: 35C
module 2 outlet temperature: 38C
module 2 inlet temperature: 28C
module 2 device-1 temperature: 28C
module 2 device-2 temperature: 35C
module 3 outlet temperature: 39C
module 3 inlet temperature: 28C
module 3 device-1 temperature: 28C
module 3 device-2 temperature: 34C
module 6 outlet temperature: 37C
module 6 inlet temperature: 31C
module 6 device-1 temperature: 27C
module 6 device-2 temperature: 34C
module 6 aux-1 temperature: 33C
module 6 aux-2 temperature: 33C
module 7 outlet temperature: 27C
module 7 inlet temperature: 22C
module 7 device-1 temperature: 32C
module 7 device-2 temperature: 33C
module 7 asic-1 (SSO-1) temp: 23C
module 7 asic-2 (SSO-2) temp: 23C
module 7 asic-3 (SSO-3) temp: 23C
module 7 asic-4 (SSO-4) temp: 23C
module 7 asic-5 (SSA-1) temp: 23C
module 7 asic-6 (HYPERION-1) temp: 23C
module 7 RP outlet temperature: 27C
module 7 RP inlet temperature: 27C
module 7 EARL outlet temperature: 35C
module 7 EARL inlet temperature: 23C
module 9 outlet temperature: 44C
module 9 inlet temperature: 27C
module 9 EARL outlet temperature: 33C
module 9 EARL inlet temperature: 34C
module 10 outlet temperature: 46C
module 10 inlet temperature: 28C
module 10 EARL outlet temperature: 33C
module 10 EARL inlet temperature: 32C
module 11 outlet temperature: 49C
module 11 inlet temperature: 28C
module 11 EARL outlet temperature: 34C
module 11 EARL inlet temperature: 35
Thanks...

Hi, you can set the green and yellow thresholds on your switch env, you can check the status with "show env temperature status" command it will tell you if the temp is too high or too low. have a look at the Cisco document below it should be helpful. HTH
Usage Guidelines
On a Cisco ME switch, you can use the show env temperature command to display the switch temperature status. The command output shows the green and yellow states as OK and the red state as FAULTY. If you enter the show env temperature status command on this switch, the temperature information is the same as the show env all command output.
You can use the system env temperature threshold yellow global configuration command to configure the yellow temperature threshold. If not configured, the yellow threshold defaults to 10 degrees Celsius below the red threshold.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.
Examples
Displays for the Cisco ME 3400G-12CS switch are different than those for other Cisco ME switches. This is an example of output from the show env all command for the Cisco ME 3400G-12CS switch:
Switch> show env all
FAN 1 is OK
FAN 2 is OK
TEMPERATURE is OK
Temperature Value: 31 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 56 Degree Celsius
Red Threshold : 66 Degree Celsius
POWER SUPPLY 1 is OK
POWER SUPPLY 2 is Alarm disabled
This is an example of output from the show env all command for other Cisco ME switches:
Switch# show env all
FAN is OK
TEMPERATURE is OK
POWER is OK
RPS is NOT PRESENT
This is an example of output from the show env fan command for the Cisco ME 3400G-12CS switch:
Switch> show env fan
FAN 1 is OK
FAN 2 is OK
This is an example of output from the show env fan command for other Cisco ME switches:
Switch> show env fan
FAN is OK
This is an example of output from the show env power command for the Cisco ME 3400G-12CS switch:
Switch> show env power
POWER SUPPLY 1 is OK
POWER SUPPLY 2 is Alarm disabled
These are examples of output from the show env temperature command for the Cisco ME 3400G-12CS switch:
Switch> show env temperature
TEMPERATURE is OK
Switch> show env temperature status
Temperature Value: 31 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 56 Degree Celsius
Red Threshold : 66 Degree Celsius

The inlet temperatures of the modules are an indication of the temp of the air beeing drawn into the Catalyst. Your switch seem to be drawing air that is around 28C, which is above the industry general recommended range for a computer room. In the long run this might affect the lifetime of your equipment.
Check if your room is colder than the inlet temps, and improve airflow into the switch if you can.
