Item Chassis component. You can congure the threshold informaon
for components such as the chassis, the Roung Engines, and FPC
for each slot in each FRU to display in the output. By default,
informaon is displayed only for the chassis and the Roung
Engines.
Fan speed Temperature thresholds, in degrees Celsius, for the fans to operate
at normal and at high speed.
• Normal—The temperature threshold at which the fans operate
at normal speed and when all the fans are present and
funconing normally.
• High—The temperature threshold at which the fans operate at
high speed or when a fan has failed or is missing.
NOTE: An alarm is triggered when the temperature exceeds the
threshold sengs for a yellow, amber, or red alarm.
Yellow or amber alarm Temperature threshold, in degrees Celsius, that triggers a yellow or
amber alarm.
• Normal—The temperature threshold that must be exceeded on
the device to trigger a yellow or amber alarm when the fans are
running at full speed.
• Bad fan—The temperature threshold that must be exceeded on
the device to trigger a yellow or amber alarm when one or more
fans have failed or are missing.
