Dell EMC PowerEdge C6420 Installation and Service Manual
Removing the system board
Prerequisites
CAUTION Do not attempt to remove the TPM plug-in module from the system board. Once the TPM plug-in module is installed, it is cryptographically bound to that specific system board. Any attempt to remove an installed TPM plug-in module breaks the cryptographic binding, and it cannot be reinstalled or installed on another system board.
CAUTION To avoid damage to the system board, ensure that the system board does not touch the side walls of the sled chassis, while sliding the system board into the sled.
- Follow the safety guidelines listed in Safety instructions.
- Follow the procedure listed in Before working inside your system.
- Remove the sled from the chassis.
- Remove the air shroud.
- Remove the expansion card risers.
- Remove the processor heat sink module.
- Remove the memory modules.
- If installed, remove OCP card.
- If installed, remove the mezzanine card.
- Remove the linking board
- Disconnect all the cables from the system board.
- Keep the Phillips #1 screwdriver and #4 nut driver ready.
Steps
- Remove the screws that secure the system board to the sled assembly.
CAUTION Do not lift the system board by holding a memory module slot, any other connector, or component.
- Hold the system board by the edges, and lift the system board away from the sled.
