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 battery with the same or equivalent type recommended by the manufacturer.

• Dispose of used batteries according to the manufacturer’s instructions.

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 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 AT­TACHED 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 touching any components or connectors. After removing a board from its
protective ESD bag 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 ESD bag. Do not slide the board
over any surface.

System power on/off: To service components within the server, please ensure the power has
been disconnected.
e.g. Remove the node from the server chassis (to disconnect power) or disconnect the power
from the server chassis.
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 chassis and disconnect the
cables attached to the system before servicing the chassis. Otherwise, personal injury or equip­ment damage 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 sensi-tive 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 n-gertips or
with a pair of ne needle nosed pliers. If the jumpers do not have such a tab, take care when us-

ing 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.

Chapter 5 BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters of the system in the EFI on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that

allows the user to modify basic system conguration settings or to activate certain system features. When the

power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to keep the

conguration values in the CMOS.

To access the BIOS Setup program, press the <DEL> key during the POST when the power is turned on.

• BIOS ashing is potentially risky, if you do not encounter problems of using the current BIOS
version, it is recommended that you don't ash the BIOS. To ash the BIOS, do it with caution.
Inadequate BIOS ashing may result in system malfunction.

• It is recommended that you not alter the default settings (unless you need to) to prevent system

instability or other unexpected results. Inadequately altering the settings may result in system's
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
(Refer to the Exit section in this chapter or introductions of the battery/clearing CMOS jumper in
Chapter 1 for how to clear the CMOS values.)
