Table 66: show chassis temperature-thresholds Output Fields
Field Name
Fire shutdown
When a temperature alarm is triggered, you can identify the condition that triggered it by running the
show chassis environment command to display the chassis temperature values for each component and
comparing those with the temperature threshold values. You can display the temperature threshold
values by running the show chassis temperature-thresholds command.
For example, for FPC 3:
• If the temperature of FPC 3 exceeds 55° C, the output indicates that the fans are operating at a high
speed (no alarm is triggered).
• If the temperature of FPC 3 exceeds 65° C, a yellow alarm is triggered to indicate that one or more
fans have failed.
• If the temperature of FPC 3 exceeds 75° C, a yellow alarm is triggered to indicate that the temperature
threshold limit is exceeded.
• If the temperature of FPC 3 exceeds 80° C, a red alarm is triggered to indicate that one or more fans
have failed.
• If the temperature of FPC 3 exceeds 105° C, a red alarm is triggered to indicate that the temperature
threshold limit is exceeded.
• If the temperature of FPC 3 exceeds 110° C, the switch is powered off.
Table 67 on page 313 lists the possible causes for the switch to generate a temperature alarm. It also
lists the respective remedies.
Table 67: Causes and Remedies for Temperature Alarms
Cause
Ambient temperature is above
threshold temperature.
Field Description
Temperature threshold, in degrees Celsius, at which the switch
shuts down in case of fire.
Remedy
Ensure that the ambient temperature is within the threshold temperature limit.
