Install a CMIOU
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.
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
). 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.
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
Open the green CMIOU levers so that they are fully open (panel
Insert the CMIOU back into its slot in the server until the levers
begin to engage (panel 3).
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
Determine your next step:
If you replaced DIMMs, return to the procedure for that
See Servicing DIMMs.
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.

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.
