Table 1: show chassis temperature-thresholds Output Fields

Field name

Field Description

Item

Chassis component. If per FRU per slot thresholds are configured, the components about which information is displayed include the chassis, the Routing Engines, FPCs, and FEBs. If per FRU per slot thresholds are not configured, the components about which information is displayed include the chassis and the Routing Engines.

Chassis Default

Default values of the chassis in degrees Celsius.

Routing Engine

Default values of the routing engine in degrees Celsius.

Fan speed

The fan speed changes at the threshold when going from a low speed to a higher speed. When the fan speed changes from a higher speed to a lower speed, the temperature changes two degrees below the threshold.

Temperature threshold settings, in degrees Celsius, for the fans to operate at normal and high speeds.

  • Normal—The fans operate at normal speed if the component is at or below this temperature and all the fans are present and functioning normally.

  • High—The fans operate at high speed if the component has exceeded this temperature or a fan has failed or is missing.

An alarm is not triggered until the temperature exceeds the threshold settings for a yellow alarm or a red alarm.

Yellow alarm

Temperature threshold settings, in degrees Celsius, that trigger a yellow alarm.

  • Normal—The temperature that must be exceeded on the component to trigger a yellow alarm when the fans are running at full speed.

  • Bad fan—The temperature that must be exceeded on the component to trigger a yellow alarm when one or more fans have failed or are missing.

Red alarm

Temperature threshold settings, in degrees Celsius, that trigger a red alarm.

  • Normal—The temperature that must be exceeded on the component to trigger a red alarm when the fans are running at full speed.

  • Bad fan—The temperature that must be exceeded on the component to trigger a red alarm when one or more fans have failed or are missing.

Fire shutdown

Temperature threshold settings, in degrees Celsius, for the device to shut down.
