Removing The Server Top Cover - Lenovo x3530 M4 Installation And Service Manual

• Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield
installed in it.
• If the server has redundant power, each of the power-supply bays has a power supply installed in it.
• There is adequate space around the server to allow the server cooling system to work properly. Leave
approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects
in front of the fans. For proper cooling and airflow, replace the server cover before you turn on the server.
• You have followed the cabling instructions that come with optional adapters.
• You have replaced a failed fan within 48 hours.
• You have replaced a hot-swap drive within 2 minutes of removal.
• You do not operate the server without the air baffles installed. Operating the server without the air baffles
might cause the microprocessor to overheat.
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.
• 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.
