3.If the faulty CP is the active CP, issue the haFailover command. Wait until the failover has completed. Use the haShow command to verify the CPs are synchronized and the failover is complete.

Depending on the nature of the CP failure, it is possible that the haFailover command may not work. Proceed to the next step anyway.

4.Enter the haDisable command. This is required before physically removing and replacing a CP blade.

5.Power off the blade by sliding the slider switch in the left ejector to the right to the off position. Do not eject the blade until the power LED is off and you have completed the next two steps.

7.Unscrew the thumb screw from both ejectors using the Phillips screwdriver.

8.Lever open both ejector handles simultaneously to approximately 45 degrees and pull the CP blade out of the chassis.
