Installation guidelines
Before you remove or replace a CRU or install an optional device, read the following information.
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, use an
electrostatic-discharge wrist strap and plug it into the Electrostatic-discharge connector on the front of the
server (near the video connector) or other grounding system when you remove or install a hot-swap device.
Before you install optional devices, read the following information:
• Read the safety information, see “Safety” on page v and the guidelines in “Handling static-sensitive
devices” on page 39. 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.ibm.com/systems/info/x86servers/serverproven/compat/us/.
• 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 Lenovo x86 servers at http://www.ibm.com/support/entry/portal/docdisplay?lndocid=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
correctly. If the server is not working correctly, see “Running the DSA Preboot diagnostic programs” on
page 177 for information about how to run diagnostics.
• Observe good housekeeping in the area where you are working. Place removed covers and other parts
in a safe place.
• Do not attempt to lift an object that you think is too heavy for you. If you have to lift a heavy object,
observe the following precautions:
– Make sure that you can stand safely without slipping.
