• 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 server 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 server 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 server 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 server 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 others’ reach to prevent possible damages.
Install server 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 the server. For a list of supported optional
components for the server, see
http://www.lenovo.com/us/en/serverproven/.
• Always download and apply the latest firmware. This will help ensure that any known issues are
addressed, and that your server is ready to work with optimal performance. Go to
ThinkSystem SR550
Drivers and Software
to download firmware updates for your server.
• It is good practice to make sure that the server is working correctly before you install an optional
component.
• Follow the installation procedures in this section and use appropriate tools. Incorrectly installed
components can cause system failure from damaged pins, damaged connectors, loose cabling, or loose
components.
