• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the

server for more than 30 minutes with the server cover removed, for it might damage server components.

• Cabling instructions that come with optional components must be followed.

• A failed fan must be replaced within 48 hours since malfunction.

• A removed hot-swap fan must be replaced within 30 seconds after removal.

• A removed hot-swap drive must be replaced within two minutes after removal.

• A removed hot-swap power supply must be replaced within two minutes after removal.

• Every air baffle that comes with the server must be installed when the server starts (some servers might

come with more than one air baffle). Operating the server with a missing air baffle might damage the
processor.

• All processor sockets must contain either a socket cover or a processor with heat sink.

• When more than one processor is installed, fan population rules for each server must be strictly followed.

Working inside the server with the power on

You might need to keep the power on with the server cover removed to look at system information on the
display panel or to replace hot-swap components. Review these guidelines before doing so.

Attention:

The server might stop responding and data loss might occur when internal server components

are exposed to static electricity. To avoid this potential problem, always use an electrostatic-discharge wrist
strap or other grounding systems when working inside the server with the power on.

• Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before

working inside the server.

• Prevent your necktie, scarf, badge rope, or long hair from dangling into the server.

• Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.

• 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.
