Step 4. Install the OCP module.
Notes:
• Ensure that the Ethernet adapter is fully seated and the thumbscrew is securely tightened.
Otherwise, the OCP module will not get full connection and may not function.
• If there is an OCP module installed, when the system is powered off but still plugged in to AC
power, system fans will continue to spin at a much lower speed. This is the system design to
provide proper cooling for the OCP module.
