Installation guidelines

Use this information for installation.
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, the guidelines in "Working inside the server with the
power on" on page 33, and "Handling static-sensitive devices" on page 33. 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/ .
