WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

You can remove and install a CMM from a powered-off system or from a powered-on system using a hot-swap procedure. The chassis cannot be managed while you
replace the CMM hardware.

Note – Make sure that you install the CMM supported for your chassis

NOTE: When replacing the chassis management module (CMM), you must restore the configuration settings maintained in the CMM. Before replacing the chassis management module (CMM), save the configuration using the Oracle ILOM backup utility. Refer to the Oracle Integrated Lights Out Manager (ILOM) 3.0.x Documentation for instructions on backing up and restoring the Oracle ILOM configuration. https://docs.oracle.com/cd/E19860-01/E21549/bbghcfdj.html

WHAT ACTIONS ARE REQUIRED:

Remove the CMM
1. Remove any cables connected to the CMM
2. Press together and hold the ejector button on the module ejector lever.
3. To unlatch the module from the chassis, pull the ejector lever away from the module and up.
4. Pull the ejector lever toward you until you are able to pull the rest of the module out by hand.

Caution – To ensure proper system cooling and operation, you must replace the CMM within one minute or you must power off the chassis.

Install the CMM

1. Align the CMM with the CMM slot.
Ensure that the CMM indicator LEDs of the CMM on the front panel are on the top of the module and facing you.

2. Slide the CMM into the vacant CMM chassis slot.Ensure that the CMM engages with the system chassis guidance system.

3. Close the ejector lever to secure the CMM in the chassis. After you install a CMM in a powered-on system, the CMM automatically begins to initialize.

CMM Reset Sequence

If you have installed the CMM in a powered-off system, the CMM completes the following sequence of operations:
1. CMM receives 3-volt auxiliary standby power and comes out of reset.
2. While the CMM boots up, the green OK LED on the CMM is set to the slow blink state.
3. When the CMM has booted, the CMM sets the green OK LED on the FIM and CMM to the standby blink state, indicating that the chassis is now ready for full power-on.
