Server Warnings and Cautions
Before installing a server, be sure that you understand the following warnings and cautions.
WARNING!
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the server.
WARNING!
To reduce the risk of personal injury from hot surfaces, allow the drives
and the internal system components to cool before touching them.
WARNING!
This server is equipped with high speed fans. Keep away from hazardous
moving fan blades during servicing.
CAUTION!
• Do not operate the server for long periods with the access panel open or removed. Operat-
ing the server in this manner results in improper airow and improper cooling that can lead to
thermal damage.
• Danger of explosion if battery is incorrectly replaced.
• Replace only with the same or equivalent type recommended by the manufacturer.
• Dispose of used batteries according to the manufacturer’s instructions.

Electrostatic Discharge (ESD)
CAUTION!
ESD CAN DAMAGE DRIVES, BOARDS, AND OTHER PARTS. WE RECOMMEND THAT YOU
PERFORM ALL PROCEDURES AT AN ESD WORKSTATION. IF ONE IS NOT AVAILABLE,
PROVIDE SOME ESD PROTECTION BY WEARING AN ANTI-STATIC WRIST STRAP AT-
TACHED TO CHASSIS GROUND -- ANY UNPAINTED METAL SURFACE -- ON YOUR SERVER
WHEN HANDLING PARTS.
Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by
their edges without any component and pin touching. After removing a board from its protective
wrapper or from the system, place the board component side up on a grounded, static free sur-
face. Use a conductive foam pad if available but not the board wrapper. Do not slide board over
any surface.
System power on/off: To remove power from system, you must remove the system from
rack. Make sure the system is removed from the rack before opening the chassis, adding, or
removing any non hot-plug components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be
present on power, telephone, and communication cables. Turn off the system and disconnect the
cables attached to the system before servicing it. Otherwise, personal injury or equipment dam-
age can result.
Electrostatic discharge (ESD) and ESD protection: ESD can damage drives,
boards, and other parts. We recommend that you perform all procedures in this chapter only at
an ESD workstation. If one is not available, provide some ESD protection by wearing an antistatic
wrist strap attached to chassis ground (any unpainted metal surface on the server) when handling
parts.
ESD and handling boards: Always handle boards carefully. They can be extremely
sensitive to electrostatic discharge (ESD). Hold boards only by their edges. After removing a
board from its protective wrapper or from the system, place the board component side up on a
grounded, static free surface. Use a conductive foam pad if available but not the board wrapper.
Do not slide board over any surface.
Installing or removing jumpers: A jumper is a small plastic encased conductor that slips
over two jumper pins. Some jumpers have a small tab on top that can be gripped with ngertips
or with a pair of ne needle nosed pliers. If the jumpers do not have such a tab, take care when
using needle nosed pliers to remove or install a jumper; grip the narrow sides of the jumper with
the pliers, never the wide sides. Gripping the wide sides can dam-age the contacts inside the
jumper, causing intermittent problems with the function con-trolled by that jumper. Take care to
grip with, but not squeeze, the pliers or other tool used to remove a jumper, or the pins on the
board may bend or break.

CAUTION!
Risk of explosion if battery is replaced incorrectly or with an incorrect type. Replace the battery
only with the same or equivalent type recommended by the manufacturer. Dispose of used bat-
teries according to the manufacturer’s instructions.

Hardware Installation
1-1 Installation Precautions
The motherboard/system contain numerous delicate electronic circuits and components which
can become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully
read the service guide and follow these procedures:
• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or
warranty sticker provided by your dealer. These stickers are required for warranty validation.
• Always remove the AC power by unplugging the power cord from the power outlet before
installing or removing the motherboard or other hardware components.
• When connecting hardware components to the internal connectors on the motherboard,
make sure they are connected tightly and securely.
• When handling the motherboard, avoid touching any metal leads or connectors.
• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic
components such as a motherboard, CPU or memory. If you do not have an ESD wrist
strap, keep your hands dry and rst touch a metal object to eliminate static electricity.
• Prior to installing the motherboard, please have it on top of an antistatic pad or within an
electrostatic shielding container.
• Before unplugging the power supply cable from the motherboard, make sure the power
supply has been turned off.
• Before turning on the power, make sure the power supply voltage has been set according to
the local voltage standard.
• Before using the product, please verify that all cables and power connectors of your
hardware components are connected.
• To prevent damage to the motherboard, do not allow screws to come in contact with the
motherboard circuit or its components.
• Make sure there are no leftover screws or metal components placed on the motherboard or
within the computer casing.
• Do not place the computer system on an uneven surface .
• Do not place the computer system in a high-temperature environment.
• Turning on the computer power during the installation process can lead to damage to
system components as well as physical harm to the user.
• If you are uncertain about any installation steps or have a problem related to the use of the
product, please consult a certied computer technician.
