8. Replace the carrier case in the drive tray. See “Installing a solid-state drive carrier” on page 51.Attention: Do not press the top of the drive. Pressing the top might damage the drive.9. Install and close the compute node cover. See “Installing and closing the compute node cover” onpage 41.Statement 21CAUTION:Hazardous energy is present when the compute node is connected to the power source. Alwaysreplace the compute node cover before installing the compute node.10. Install the compute node into the IBM Flex System Enterprise Chassis. See “Installing the computenode in an IBM Flex System Enterprise Chassis” on page 93.11. If you replaced the part because of a service action, verify the repair by checking that the amberenclosure fault LED is off. For more information, see “Compute node control panel button andLEDs” on page 11.Removing a DIMMThe very low profile (VLP) dual-inline memory module (DIMM) is a tier 1 CRU. You can remove ityourself. If IBM removes a tier 1 CRU at your request, you will be charged for the removal. The lowprofile (LP) DIMM is a tier 2 CRU. You can remove it yourself or request IBM to remove it, at noadditional charge, under the type of warranty service that is designated for the compute node.About this taskTo remove a DIMM, complete the following steps:Procedure1. Read the Safety topic and the “Installation guidelines” on page 35.2. Shut down the operating system on all partitions of the compute node, turn off the compute node,and remove the compute node from the IBM Flex System Enterprise Chassis. See “Removing thecompute node from an IBM Flex System Enterprise Chassis” on page 37.3. Carefully lay the compute node on a flat, static-protective surface, with the cover side up.4. Open and remove the compute node cover. See “Removing the compute node cover” on page 39.5. Locate the DIMM connector that contains the DIMM being replaced.Note: You can use the system-board LEDs and the service label located on the inside of the cover toidentify the DIMM that must be replaced. See “System-board LEDs” on page 17.Chapter 6. Installing and removing components 55
