Attention:
• Read
“Installation Guidelines” on page 35 and “Safety inspection checklist” on page 36 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 42.
• 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.
• After replacing the firmware and RoT security module, update the firmware to the specific version
supported by the server. Make sure that you have the required firmware or a copy of the pre-existing
firmware before you proceed.
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/sr655v3/7d9e/downloads/driver-
