following procedures:
• Restarting the computer for maintenance without a PIN or startup key
• Updating firmware
• Upgrading critical early boot components
• Upgrading the system board to replace or remove the TPM
• Disabling or clearing the TPM

DIMM handling guidelines
CAUTION: Failure to properly handle DIMMs can cause damage to DIMM components and the
system board connector.
When handling a DIMM, observe the following guidelines:
• Avoid electrostatic discharge (on page 13).
• Always hold DIMMs by the side edges only.
• Avoid touching the connectors on the bottom of the DIMM.
• Never wrap your fingers around a DIMM.
• Avoid touching the components on the sides of the DIMM.
• Never bend or flex the DIMM.
When installing a DIMM, observe the following guidelines:
• Before seating the DIMM, open the DIMM slot and align the DIMM with the slot. Some servers require
the use of a DIMM tool to open the slots. For more information, see the server user guide.
• To align and seat the DIMM, use two fingers to hold the DIMM along the side edges.
• To seat the DIMM, use two fingers to apply gentle pressure along the top of the DIMM.
