Table 95: show chassis temperature-thresholds Output Fields (Connued)
Field Name Field Descripon
Fire shutdown Temperature threshold, in degrees Celsius, at which the switch
shuts down in case of re.
When a temperature alarm is triggered, you can idenfy the condion 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 operang 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 o.
Table 96 on page 339 lists the possible causes for the switch to generate a temperature alarm. It also
lists the respecve remedies.
Table 96: Causes and Remedies for Temperature Alarms
Cause Remedy
Ambient temperature is above
threshold temperature.
Ensure that the ambient temperature is within the threshold temperature limit.
