How to Remove Components to Reduce Weight

This procedure describes how to remove components from your server so that two persons can lift it into the rack. If you are going to use a mechanical lift, you do not need to perform this procedure.

Before You Begin

---

Caution - Circuit boards and hard drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these devices. Do not touch the components without antistatic precautions, especially along the connector edges. For more information, refer to Antistatic Precautions and Procedures in Sun Fire X4800 Server Service Manual.

1. Mark all CPU modules with their slot numbers.

   ---

   Caution - To prevent system failure, you must return CPU modules to their original locations. Mark CPU module slot locations carefully before removing them from the chassis.

   ---

2. Remove the CPU modules from the front of the chassis.

   The chassis contains four CPU module slots; each must have a CPU module or a filler panel.

   ---

   Note - Because of their light weight, there is no need to remove filler panels.

   ---

   
   

   For each CPU module:

   1. Pinch the green tabs to release the ejectors (1).
   2. Pull both ejectors out to release the module (2).

      ---

      Caution - When the module is partway out of the chassis, close the ejectors, and grasp the module. Do not handle the module by the ejectors.

      ---

   3. Gently slide the module forward until it is clear of the chassis (3).

      ---

      Caution - The CPU module is heavy. Use two hands.

      ---

   4. Close the ejectors on the CPU module.
   5. Place the CPU module on an antistatic mat.
3. Remove the four power supplies from the front of the chassis.
   1. Pinch the handle to release the lever (1).
   2. Pull the lever (2) to release the power supply.
   3. Slide the power supply out of the chassis (3).
   
   
4. Remove the PCIe express modules from the back of the chassis.

   The upper bays can be used as a hand hold when moving the chassis.

   ---

   Caution - Do not insert forks from a lift device into these open bays, as this causes severe and non-repairable damage.

   ---

   
   
   1. Mark all PCIe EM cards with their slot locations.

      ---

      Caution - To prevent system failure, you must return PCIe EM cards to their original locations. Mark PCIe EM slot locations carefully before removing them from the chassis.

      ---

   2. Rotate the lever (1) to release the module.
   3. Slide the module out of the chassis (2).
5. Remove the upper left fan module (FM2) if necessary.

   Squeeze the clamp (1) to release the fan module (2), then pull it from the chassis (3).

   You can use the recess as a hand-hold when moving the chassis.

   ---

   Caution - Do not insert forks from a lift device into this open bay, as this causes severe and non-repairable damage.
