Removing Individual Fans
Cooling and air flow: Once you remove an individual fan, make sure you replace it within two
minutes. If you cannot replace it, insert the original unit. When you have the replacement unit,
repeat the replacement procedure. Vacant spaces formerly occupied by fans alter air flow patterns
in the server system and may cause environmental conditions to exceed the environmental limits of
the server.

2. Remove the front cover. See "Removing the Front Cover" on page 50.
3. Place your ring finger and thumb in the fingerholds of the fan in the chassis.
4. Gently pull the fan directly upward and out of the fan board assembly.

recognize the absence of the fan. Before replacing the fan, make sure that
the LED shows a fault and recognizes that the slot for the fan is vacant.
