Before installing components in your compute node, read the installation guidelines.
- Read the safety information and guidelines to ensure your safety at work:
A complete list of safety information for all products is available at:
The following guidelines are available as well: Handling static-sensitive devices and Working inside the server with the power on.
Make sure the components you are installing are supported by your compute node. For a list of supported optional components for the compute node, see Lenovo ServerProven website.
- 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.ImportantSome 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.
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.
You do not have to turn off the compute node to remove or install hot-swap power supplies, hot-swap fans, or hot-plug USB devices. However, you must turn off the compute node before you perform any steps that involve removing or installing adapter cables, and you must disconnect the power source from the compute node before you perform any steps that involve removing or installing a riser card.
Blue on a component indicates touch points, where you can grip to remove a component from or install it in the compute node, open or close a latch, and so on.
Terra-cotta on a component or a terra-cotta label on or near a component indicates that the component can be hot-swapped if the server and operating system support hot-swap capability, which means that you can remove or install the component while the server is still running. (Terra-cotta can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.
- The Red strip on the drives, adjacent to the release latch, indicates that the drive can be hot-swapped if the compute node and operating system support hot-swap capability. This means that you can remove or install the drive while the compute node is still running.NoteSee the system specific instructions for removing or installing a hot-swap drive for any additional procedures that you might need to perform before you remove or install the drive.
After finishing working on the compute node, make sure you reinstall all safety shields, guards, labels, and ground wires.
