Handling Static-Sensitive Devices; Install Compute Node Hardware Options - Lenovo ThinkSystem SN850 Setup Manual

• Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before
working inside the server.
• Prevent your necktie, scarf, badge rope, or hair from dangling into the server.
• Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.
• Remove items from your shirt pocket, such as pens and pencils, in case they fall into the server as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.

Handling static-sensitive devices

Use this information to handle static-sensitive devices.
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.
• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor
humidity and increase static electricity.
• Always use an electrostatic-discharge wrist strap or other grounding system, particularly when working
inside the compute node with the power on.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the compute node for at least two seconds. This drains static electricity from the package and
from your body.
• Remove the device from the package and install it directly into the compute node without putting it down.
If it is necessary to put the device down, put it back into the static-protective package. Never place the
device on the compute node or on any metal surface.
• When handling a device, carefully hold it by the edges or the frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Keep the device from untrained technician to prevent possible damages.

Install compute node hardware options

This section includes instructions for performing initial installation of optional hardware. Each component
installation procedure references any tasks that need to be performed to gain access to the component
being replaced.
Installation procedures are presented in the optimum sequence to minimize work.
Attention: To ensure the components you install work correctly without problems, read the following
precautions carefully.
• 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
• Always 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
SN850 Drivers and Software
• It is good practice to make sure that the compute node is working correctly before you install an optional
component.
