The fan tray continues to operate indefinitely and provides 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
LEDs and Fan Tray Controller LEDs" on page
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.
