Install a CMIOU

Language:

Caution - If you remove this component while the server is powered on, wait 30 seconds before installing the replacement component. Doing so ensures that Oracle ILOM has enough time to detect the new component, which is required for the software to power it on.

Note - SPARC M7 CMIOUs are not supported in SPARC M8-8 servers. SPARC M8 CMIOUs are not supported in SPARC M7-16 servers or SPARC M7-8 servers containing one static PDomain (one to eight CMIOUs). SPARC M7-8 servers with two static PDomains are the only SPARC M7 servers that support SPARC M8 CMIOUs (and only in PDomain_1). See Mixed CMIOU Configurations for more information.

If you removed the CMIOU cover, reinstall it and slide the cover forward until the latch clicks into place.

Install the CMIOU.
1. Carefully slide the CMIOU less than half way into the slot, taking care to avoid bumping the connectors on the back of the CMIOU (panel 1).
2. Open the green CMIOU levers so that they are fully open (panel 2).
3. Insert the CMIOU back into its slot in the server until the levers begin to engage (panel 3).
4. Press the levers back together toward the center of the CMIOU, and then press the levers firmly against the CMIOU to fully seat the CMIOU into the server (panel 4).
  The levers should click into place when the module is fully seated in the server.

Determine your next step:
1. If you replaced DIMMs, return to the procedure for that component.
  See Servicing DIMMs.
2. If you replaced the entire CMIOU, check the event logs to determine whether an FPGA update is required, update the firmware, if needed, and proceed to the next step.
```
-> show /SP/logs/event/list/
Event ID   Date/Time                Class    Type  Severity
256        Tue Dec 15 07:21:23 2015 Chassis  Log   major
/SYS/CMIOU6/FPGA update required.
```
  If an FPGA update is required, refer to the SPARC M8 and SPARC M7 Servers Product Notes for information about performing the update.
3. If you replaced the entire CMIOU or removed a CMIOU as part of another service procedure, connect to the host console, then connect to the host and restart it.
  Connect to the host console in a separate terminal session to ensure that you can view all messages reported by the system.
```
-> start /Servers/PDomains/PDomain_x/HOST/console
Are you sure you want to start
/Servers/PDomains/PDomain_x/HOST/console (y/n) ? y
Connecting /Servers/PDomains/PDomain_x/HOST/console

-> start /Servers/PDomains/PDomain_x/HOST
Are you sure you want to start all of the configured hosts 
on the system (y/n) ? y
hostname starting
```
Verify that the fault has been cleared and the replaced component is operational.
See Verify That a Fault Has Been Cleared.
