System Reliability Guidelines; Handling Static-Sensitive Devices; Returning A Device Or Component; Updating The Compute Node Configuration - Lenovo ThinkServer sd350 Installation And Service Manual

System reliability guidelines

Use these guidelines to ensure that the compute node meets the cooling and system reliability requirements:
• Each microprocessor socket always contains a heat-sink filler or a microprocessor and heat sink. If the
compute node has only one microprocessor, it must be installed in microprocessor socket 1.
• The air baffles are installed over the DIMM connectors.
• The ventilation holes on the compute node are not blocked.

Handling static-sensitive devices

Use this information to handle static-sensitive devices.
Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep
static-sensitive devices in their static-protective packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around you.
• The use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist
strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system
when working inside the server with the power on.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Do not leave the device where others can handle and damage it.
• 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 2 seconds. This drains static electricity from the package and from
your body.
• Remove the device from its package and install it directly into the server without setting down the device.
If it is necessary to set down the device, put it back into its static-protective package. Do not place the
device on the server cover or on a metal surface.
• Take additional care when handling devices during cold weather. Heating reduces indoor humidity
and increases static electricity.

Returning a device or component

If you are instructed to return a device or component, follow all packaging instructions, and use any
packaging materials for shipping that are supplied to you.

Updating the compute node configuration

Use this information to update the compute node configuration.
When the compute node starts for the first time after you add or remove an internal device, you might
receive a message that the configuration has changed. The Setup utility automatically starts so that you
can save the new configuration settings. See "Using the Setup utility" on page 34 for more information
about the Setup utility.
Some devices have device drivers that you must install. See the documentation that comes with each
device for information about installing device drivers.
The compute node operates as a symmetric multiprocessing (SMP) compute node, regardless of how many
microprocessors are installed. For optimum performance, you must upgrade the operating system to
support SMP. See your operating-system documentation for additional information.
