To remove and install individual fans, follow these steps:
Caution: 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.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Remove the top cover. See "Removing the Top Cover" on page 25.
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.
5. Slide the replacement fan into the fan board assembly.
6. When you start to feel some resistance, gently push down on the center of the fan
until the connectors solidly join.
7. Install the top cover. See "Installing the Top Cover" on page 25.
Note: After removing an individual fan, the system takes a few seconds to 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.
Follow the instructions in this section to remove and install the hard drive bay.
The chassis contains one hard drive bay. The hard drive bay accommodates up to five
3.5-inch by 1.0-inch hot-swap Ultra 160 SCSI SCA hard drives.
