Installation guidelines
Use the installation guidelines to install the Lenovo System x3500 M4 Type 7383.
Attention: Static electricity that is released to internal server components when the server is powered-on
might cause the system to halt, which might result in the loss of data. To avoid this potential problem,
always use an electrostatic-discharge wrist strap or other grounding system when removing or installing a
hot-swap device.
Before you install optional devices, read the following information:
• Read the safety information in “Safety” on page v and the guidelines in “Working inside the server with
the power on” on page 37, and “Handling static-sensitive devices” on page 37. This information will
help you work safely.
• Make sure that the devices that you are installing are supported. For a list of supported optional devices
for the server, see http://www.lenovo.com/ serverproven/.
• When you install your new server, take the opportunity to download and apply the most recent firmware
updates. This step will help to ensure that any known issues are addressed and that your server is ready
to function at maximum levels of performance. To download firmware updates for your server, go to
http://www.ibm.com/support/ fixcentral.
Important: Some cluster solutions require specific code levels or coordinated code updates. If the
device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution
before you update the code.
For additional information about tools for updating, managing, and deploying firmware, see the ToolsCenter
for System x and BladeCenter at https://support.lenovo.com/us/en/ documents/LNVO-CENTER
• Before you install optional hardware, make sure that the server is working correctly. Start the server, and
make sure that the operating system starts, if an operating system is installed, or that a 19990305 error
code is displayed, indicating that an operating system was not found but the server is otherwise working
