•  Read “Installation Guidelines” on page 47 and “Safety inspection checklist” on page 48 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” on page 62.
•  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.
Firmware and driver download: You might need to update the firmware or driver after replacing a 
component. 
•  Go to 
https://datacentersupport.lenovo.com/products/servers/thinksystem/sr665v3/downloads/driver-list/ to 
see the latest firmware and driver updates for your server.
•  Go to 
“Update the firmware” on page 467 for more information on firmware updating tools.
