Use a small screwdriver to gently press the release button and release the catch while pulling gently
forward on the service controller. The service controller will move slightly forward.
Note: If you meet any resistance, do not press harder, or you might damage the release mechanism.
6. You can stop pressing the release button and pull the service controller fully out of the frame, as
shown in Figure 84
Note: When you replace a service controller, it is normal to change the worldwide node name
(WWNN) of the new service controller to match the one that is being replaced. In this case, you will
have two service controllers with the same WWNN. Clearly label the service controller that you are
removing and indicate that its WWNN is now a duplicate and that it must not be connected to a SAN
before its WWNN is reset.
