• Remove items from your shirt pocket, such as pens and pencils, in case they fall into the server as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.
Handling static-sensitive devices
Review these guidelines before you handle static-sensitive devices to reduce the possibility of damage from
electrostatic discharge.
Attention:
Prevent exposure to static electricity, which might lead to system halt and loss of data, by
keeping static-sensitive components in their static-protective packages until installation, and handling these
devices with an electrostatic-discharge wrist strap or other grounding system.
• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor
humidity and increase static electricity.
• Always use an electrostatic-discharge wrist strap or other grounding system, particularly when working
inside the server with the power on.
• 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 two seconds. This drains static electricity from the package and from your
body.
• Remove the device from the package and install it directly into the server without putting it down. If it is
necessary to put the device down, put it back into the static-protective package. Never place the device
on the server or on any metal surface.
• When handling a device, carefully hold it by the edges or the frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Keep the device from others’ reach to prevent possible damages.
Technical rules
Refer to the below technical rules and limitations when you install the related server components.
Technical rules for processor and heat sink
The following lists the supported heat sink for processors of different default TDP.

Rules about 280-watt processor installation
The following are rules to be followed when the server is configured with a 280-watt processor.
• Ethernet adapters with AOC is not supported in PCIe slot 2.
• 10/25 GbE Ethernet adapters with AOC are supported in PCIe slot 1 or 3 when the ambient temperature is
less than 30°C.
• 100/200 GbE Ethernet adapters are supported in PCIe slot 1 or 3 when the ambient temperature is less
than 30°C.
