Before performing the following procedure, read “Safety Notices” on page xi.
Removing a Processor Fan in a Non-Hot-Swap Environment
Note: A processor fan in a non-hot-swap environment means that your system is
configured at the factory with one processor fan installed. To place your system
into an environment that enables the hot-swapping of the processor fans, you
must purchase a second processor fan and insert it into the unused docking
connector. It is not necessary to shut down the system when adding the second
processor fan.
To remove a processor fan in a non-hot-swap environment, do the following:
1. On a Model 6C4, open the front and rear rack doors and place the system into the
service position as described in “Placing the Model 6C4 into the Service Position”
on page 355.
On a Model 6E4, open the bezel door.
2. Shut down the system as described in “Stopping the System” on page 350.
3. Disconnect the power source from the system.
Note: This system may be equipped with a second power supply. Before continuing
with this procedure, ensure that the power source to the system has been
completely disconnected.
4. Continue with the procedure in “Hot-Swap Fan Assembly Removal” on page 393.
