How to Install a CPU Module (CMOD)

Before You Begin

Sun Fire X4800 Server CPU Module (CMOD) and Filler Module Overview

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

   For slot designations and population rules, see CPU Module (CMOD) Designation and Population Rules.

2. If necessary, remove the filler or CMOD that occupies the slot. See How to Remove a CMOD Filler or How to Remove a CPU Module (CMOD).
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.

   Caution - Pinch point. Keep your fingers clear of the back side of the lever, the lever hinges, and the edges of the module.

   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.

   Caution - Pinch point. When operating the lever keep your fingers clear of the back side of the lever, the lever hinges, and the edges of the module.

   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.
