If one fan on the tray fails, the other fans continue to run. A sensor on the
supervisor engine monitors internal air temperature. If the air temperature
exceeds a specified threshold, the environmental monitor displays warning
messages. Threshold and status level descriptions are provided in the

Supplies”
section.
To replace a fan assembly, see
Chapter 4, “Removing and Replacing FRUs.”
