How to Remove a CPU Module (CMOD)

1.Shutdown OS and power off server.

2.To unlock the CMOD, squeeze together the green tabs between the lever handles.
This action produces a click sound and releases the handles.

3.To disengage the CMOD, simultaneously rotate both levers outward away from the center of the module. Do not attempt to remove the CMOD now.
Rotating the levers outward causes the pawls on the end of the levers to engage the sidewall of the chassis and pull the CMOD out of its internal connector.

4.Use the handles to pull the CMOD partially out of its slot.
Pull the CMOD out so that approximately 6 inches extends from the front of the chassis.

5.Rotate the levers inward until they are closed and locked.

6.To remove the CMOD, have an assistant support the CMOD as you grab it with your hands and slowly pull it out the slot.

How to Remove the CPU Module (CMOS) Battery

1.Press the cover release button on the top of the cover.

2.Slide the cover toward the back of the CMOD until it stops (approximately 0.5 inch).

3.To remove, lift the cover straight up.

4.Find the CMOS battery retainer on the left side looking at the front of the CMOD just behind the P1D7 and P1D6 DIMM slots.

5.To dislodge the battery from the retainer, place your finger under the side of the battery and gently lift the battery up and out of the retainer.



Install the replacement CMOS on the system board, then install CMOD cover

1.Unpack the replacement battery.

2.Press the new battery into the battery retainer with the positive side (+) facing up.

3.Set the cover on top of the CMOD with the cover release button toward the front of the module and with approximately 0.5 inch of the cover overhanging the rear of the module.  This leaves a gap of approximately 0.5 inch between lead edge of the cover and front top edge of the CMOD chassis. The cover should sit evenly on top of the module.

4.Slide the cover toward the front of the module until it stops, taking care that the lead edge of the cover slides under the front top edge of the CMOD.
When the cover is properly installed, this action produces a click sound as the cover latch engages and locks the cover.

5.Ensure that the cover is locked in place.  The cover should not move unless the release button is pressed.


Install a CPU Module (CMOD)

1.Locate the module slot that you need to populate.

2.If necessary, remove the filler or CMOD that occupies the slot.

3.Open the CMOD levers to the fully open position by squeezing together the green locking tabs on the lever handles and rotating both handles outward, away from the center of the module.  The levers do not extend beyond 90 degrees.

4.Orient the CMOD so that the cover faces upward.

5.Carefully slide the module into the chassis until it stops.
Do not force the module into the chassis in an attempt to engage the connectors on the chassis midplane.

6.Ensure that the pawl on the end of each lever is aligned with the rectangular slot in the chassis sidewall.

7.To latch and lock the CMOD, simultaneously rotate and push both levers inward toward the center of the module until the locks on the handles click into place.

This action pushes the module into the chassis and engages the connector on the back of the module with the connector on the interior midplane. When the handles are locked, you cannot lift the levers without first releasing the locks on the handles


8.To latch and lock a filler module, keep your fingers clear of the back side of the handle and push the lever inward and to the left until the lock clicks into place.

This action pushes the filler module into the chassis. When the handle is locked, you cannot lift the levers without first releasing the lock on the handle.


How to verify the CMOD working properly.

Power on server and log in ILOM to confirm if CPU working properly.

1.Check CMOD status from ILOM

1.1 show /SYS/BLx
note: the "x" means which CMOD and which your repalced CMOD

example

1.2 Check if any error output from event log

example

1.3 Check if any fault parts existed

example

If fault existed, follow below doc try clear fault.

Doc ID 1381773.1
How to clear FMA logs on the ILOM or Solaris:ATR:1381773.1:1 (Doc ID 1381773.1)
https://support.us.oracle.com/oip/faces/secure/km/DocumentDisplay.jspx?id=1381773.1

2.Check if CMOD working normal on Solaris said.

2.1 Use prtdiag -v command

example

2.3 Check FMA info if any error existed

example

2.4 Check /var/adm/messages file if any error existed

example
