Lenovo thinksystem SN850 7X15, Setup Manual

Page: 34 / 88

Notes:
• The first generation Chassis Management Module (CMM1; 68Y7030) is not supported by the ThinkSystem
SN850 compute node.
• The second generation Chassis Management Module (CMM2; 00FJ669) must be at firmware level 1.6.1 or
above to support the ThinkSystem SN850 compute node. This applies to both CMMs that are installed in
the chassis.
Installation Guidelines
Use the installation guidelines to install components in your server.
Before installing optional devices, read the following notices carefully:
Attention: 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.
• Read the safety information and guidelines to ensure that you work safely.
– A complete list of safety information for all products is available at:
http://thinksystem.lenovofiles.com/help/topic/safety_documentation/pdf_files.html
– The following guidelines are available as well: “Handling static-sensitive devices” on page 28 and
“Working inside the compute node with the power on” on page 27.
• Make sure the components you are installing are supported by the compute node. For a list of supported
optional components for the compute node, see http://www.lenovo.com/serverproven/.
• When you install a new compute node, download and apply the latest firmware. This will help ensure that
any known issues are addressed, and that your compute node is ready to work with optimal performance.
Go to ThinkSystem SN850 Drivers and Software to download firmware updates for your compute node.
Important: Some cluster solutions require specific code levels or coordinated code updates. If the
component is part of a cluster solution, verify that the latest level of code is supported for the cluster
solution before you update the code.
• Before you remove a compute node from the Flex System chassis, you must shut down the operating
system and turn off the compute node. You do not have to shut down the chassis itself.
• It is good practice to make sure that the compute node is working correctly before you install an optional
component.
• Keep the working area clean, and place removed components on a flat and smooth surface that does not
shake or tilt.
• Do not attempt to lift an object that might be too heavy for you. If you have to lift a heavy object, read the
following precautions carefully:
– Make sure that you can stand steadily without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy object.
– To avoid straining the muscles in your back, lift by standing or by pushing up with your leg muscles.
• Make sure that you have an adequate number of properly grounded electrical outlets for the compute
node, monitor, and other devices.
• Back up all important data before you make changes related to the disk drives.
• Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx screwdriver available.
• To view the error LEDs on the system board and internal components, leave the power on.
