Install the processor board
Follow instructions in this section to install the processor board.
About this task
- This task must be operated by trained technicians that are certified by Lenovo Service. Do not attempt to remove or install the part without proper training and qualification. 
- When the server has an LACM module (close-loop cooling module) installed, you must apply for a handle first if you need to install or remove the processor board, I/O board, and processor. However, while replacing the old LACM module with a new one, you do not need to apply for a handle as the new LACM module contains it. 
- Read Installation Guidelines and Safety inspection checklist to ensure that you work safely. 
- Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server. 
- Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system. 
- Go to Drivers and Software download website for ThinkSystem SR645 V3 to see the latest firmware and driver updates for your server. 
- Go to Update the firmware for more information on firmware updating tools.
