circulation across the components inside the expansion unit. Air
flows through the expansion unit from the front to the back.
You can hot-swap the fans (replace them while the expansion unit is
turned on and running), as long as you complete the exchange
within 10 minutes. This time limit applies only to the total time that
a fan is out of the expansion unit, beginning when you remove the
failed unit and ending when you reseat the new one. This does not
include the time it takes you to perform this entire procedure
(checking LEDs, unpacking the new fan, and so on).
Both fan units must always be in place, even if one is not
functioning properly, to maintain proper cooling.
Note: Refer to Table 2 on page 60 for more information on LEDs.
