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 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 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 sur­face. 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 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
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 bat­teries according to the manufacturer’s instructions.

- 41 - 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 <F2> key during the POST when the power is turned on.

Chapter 1 BIOS Setup

• 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.)
