System reliability guidelines

Review the system reliability guidelines to ensure proper system cooling and reliability.
Make sure the following requirements are met:
• When the server comes with redundant power, a power supply must be installed in each power-supply
bay.
• Adequate space around the server must be spared to allow 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 any
object in front of the fans.
• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the
server for more than two 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.
• 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.

Handling static-sensitive devices

Use this information to handle static-sensitive devices.
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.

Install server hardware options

This section includes instructions for performing initial installation of optional hardware. Each component
installation procedure references any tasks that need to be performed to gain access to the component
being replaced.
Installation procedures are presented in the optimum sequence to minimize work.
