Step 4 Grasp the fan tray handle and pull it out only partially (0.25 inches), to unmate the connector and unseat it
from the backplane. After unmating the connector, allow three seconds to let the fan blades stop spinning
completely.
When unmating the connector, gently move the fan tray from side to side, if necessary. The fans are equipped
with a braking mechanism that fully stop the blades within three seconds of being de-energized (You will not
be able to visualy inspect the fan to see whether the blades are spinning or not).
Step 5 Place your other hand underneath to support the bottom of the fan tray and then slide it out of the bay
completely.
Only the fan tray is removed from the chassis (excluding the adapter).
What to do next
Set the removed fan tray aside and immediately proceed with installing the replacement or spare fan tray.
