	An unplanned CPU module replacement on a FAS250 or a nonclustered FAS270	If possible, shut down the appliance by entering the following command at the console: halt Caution Use the `halt` command to perform a clean shutdown whenever possible.
	A planned CPU module replacement on a clustered FAS270c	Determine which module is to be replaced. From the partner CPU module, perform a takeover operation by entering the following command: `cf takeover`
	An unplanned CPU module replacement on a clustered FAS270c, where the partner node did or did not perform a takeover	Proceed to Step 2.
2	Put on the antistatic wrist strap and attach the grounding leash to the appliance chassis.
3	Disconnect all cables to the CPU module that you are replacing.
4	At the rear-center of your appliance, using your thumb and index finger of both hands, press the cam mechanism levers in the middle of the CPU module to release it. The following figure shows how to release the cam mechanism.
