The fan tray continues to operate indefinitely and provide sufficient cooling even when a single fan fails,
provided the room temperature is within the operating range. You can check the status of fans by viewing
the LEDs on each fan tray. See “PTX10000 Fan Tray LEDs and Fan Tray Controller LEDs” on page 53.
You cannot replace a single fan. If one or more fans fail, you must replace the entire fan tray.
In addition to the fan trays, there is an internal fan in each power supply.
