NOTE
✏
Notes provide information and may be used to emphasize a recommended
sequence of steps.
<F1> A letter, number, symbol, or word enclosed in < > represents a key on your keyboard.
For example, the instruction "press <F1>" means press the key labeled "F1" on your
keyboard.
<Enter> The <Enter> key is used to enter commands and responses to prompts. Some manuals
refer to <Enter> as RETURN, CARRIAGE RETURN, <CR>, or use an arrow. All of
these terms are interchangeable.
<x + y> Two or three key names, separated by plus signs, indicate multiple-key entries. For
example, <Ctrl + Alt + Del> means hold down <Ctrl> and <Alt> and press <Del>.
_L In all tables in this guide, active-low signal names have an “_L” symbol following the
name; for example, DSTBN3_L. Active-high signal names do not have a “_L” suffix.

1 Introduction to the High-performance Server
The modular scaleable architecture of your high-performance rack server supports symmetrical
multiprocessing (SMP) and a variety of operating systems. The server comes with Peripheral
Component Interconnect (PCI) and Industry Standard Architecture (ISA) buses. The server board
set consists of eight individual boards.
• CPU baseboard
• Two memory modules
• Front side bus terminator module
• PCI hot-plug (PHP) I/O baseboard
• I/O riser card
• Front panel board
• Midplane
• LVDS (low-voltage differential signal) SCSI hot-swap peripheral bay backplane
The CPU baseboard is mounted horizontally toward the front of the chassis, and the PHP I/O
baseboard is mounted horizontally towards the rear of the chassis. The baseboards plug into
connectors on the midplane mounted between them. The midplane interconnects the baseboards
with the memory modules and power supplies. The front panel board is mounted in front of the
CPU baseboard in the same plane. It provides the user interface, server management, cooling
system control, and power control.

Power system with r edundancy The 750 watt, 220 VAC autoranging power supplies include integrated
fans for cooling. In a rack server with three supplies (2 + 1), the third
one is redundant. The supplies can be replaced—hot-swapped—
without turning the server power off. The server requires a minimum of
two power supplies. LEDs on the back of the power supply indicate
power on, failure, and predictive failure.
Server chassis The electrogalvanized metal used in manufacturing the server chassis
minimizes electromagnetic interference (EMI) and radio frequency
interference (RFI).

5.25-inch IDE CD-ROM drive in the 5.25-inch half-height bay.
Two 3.5-inch wide by 1.0-inch or 1.6-inch hot-swappable LVDS hard
disk drives mounted side-by-side in the 3.5-inch hot-docking bays. The
hot-docking bays allow hot-swapping of hard disk drives without
shutting down the server.
Three power supply bays populated with either two or three power
supplies.
Ten I/O expansion slot covers.
The plastic front bezel provides airflow and easy access to drives in the
hot-docking bays. The removable top covers provide proper airflow
and easy access to components inside the server. A padlock (not
supplied) on the back of the chassis secures the covers to prevent
unauthorized entry into the server—only technically qualified personnel
should remove the server covers.
Cooling system with redundancy Six fans (5 + 1) cool and circulate air through the server. The sixth fan
is redundant. The fans can be replaced—hot-swapped—without
turning the server power off. An LED mounted next to each fan
guarantees positive identification of the failed fan.
Integrated power supply fans—two or three—cool and circulate air
through the power supplies and the bottom of the chassis.

Server Security
There are several ways to prevent unauthorized entry or use of the server.
Security with the Setup utility:
• Set server administrative and user passwords.
• Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel
controls.
Security with the System Setup Utility (SSU):
• Enable the keyboard lockout timer so that the server requires a password to reactivate the
keyboard and mouse after a specified time-out period—1 to 128 minutes.
• Set an administrative password.
• Set a user password.
• Activate the secure mode hot-key.
• Disable writing to the diskette drive.
Password Protection
BIOS passwords prevent unauthorized tampering with the server. If you set the user password, but
not the administrative password, the BIOS requires you to enter the user password before you can
boot the server or run the SSU. If you set both passwords, entering either password lets you boot
the server or enable the keyboard and mouse. Only the administrative password lets you change
the server configuration with the flash-resident Setup utility.
Secure Boot Mode
The secure boot mode allows the server to boot and run the operating system (OS). However, you
cannot use either the keyboard or the mouse until you enter the user password.
You can use Setup to put the server in the secure boot mode. If the BIOS detects a disk in the
CD-ROM drive or a diskette in floppy drive A at boot time, it prompts you for a password. When
you enter the password, the server boots from the disk in the CD-ROM drive or the diskette in
drive A. Entering a password also disables the secure mode.
If there is no disk in the CD-ROM drive or diskette in drive A, the server boots from drive C. It
automatically goes into secure mode. All enabled secure mode features go into effect at boot time.
If you set a hot-key combination, you can secure the server immediately.
Boot Sequence Contr ol
The BIOS security features determine the boot devices and the boot sequence. They also control
disabling writes to the diskette drive in secure mode. You can use the SSU to select each boot
device. The default boot sequence is diskette, hard disk, CD-ROM, and Network.
26
Chapter 1 Introduction to the High-performance Server
Boot Without Keyboard
The server can boot with or without a keyboard. Before it boots, the BIOS displays a message
about the keyboard stating whether or not it detects one. During POST, the BIOS automatically
detects and tests the keyboard if it is present.
Locked Power and Reset Switches
The power and reset push-button switches on the front panel are locked when the server is in the
secure mode. To exit from the secure mode, you must enter your user password.
Diskette Write Protect
If Diskette Write Protect is enabled in Setup, it write-protects the diskette drive only while the
server is in the secure mode. To exit from the secure mode, you must enter your user password.
Video Blanking
If Video Blanking is enabled in Setup, the video display will be off when the server is in the secure
mode. To exit from the secure mode, you must enter your user password.
Emergency Management Port (EMP)
The Emergency Management Port (EMP) is a feature of Server Management. EMP lets the Front
Panel Controller (FPC) communicate with a EMP console via the serial port even if the server
power is off. To enable this feature in the flash-resident Setup, an administrator must enter a
unique EMP password. If the administrator enters a new EMP password or clears an old one, the

If the administrator sets the Password Clear jumper to the Clear position, the BIOS clears the
administrator and user passwords. It also attempts to clear the EMP password. If the FPC is not
present or is not functioning properly, the BIOS times out and continues.

2 On-site Installation: Installing the Server
This chapter tells how to:
• Select a site
• Connect input and output devices
• Turn on the server and create installation diskettes from the Server System Configuration
Software CD
• Read and print a copy of this manual
• Exit to DOS
WARNING
The minimum server configuration weighs about 51.4 kg (113 lbs), and
the maximum one weighs close to 60 kg (132 lbs). To avoid personal
injury, have someone help you move the server. Do not attempt to lift
or move the server by holding the handles on the power supply.
Selecting a Site
The server operates reliably within the specified environmental limits (see page 30). The chosen
site must be close to a grounded power outlet applicable for the electrical code of that region. The
minimum available power requirements are described in Chapter 20, “Power System:
Description/Calculating Power Usage”.
CAUTION
Ensure that the power service connection is through a properly grounded
outlet.
The site must also be:
• Clean and dust-free
• Well ventilated and away from sources of heat
• Isolated from strong electromagnetic fields and electrical noise caused by electrical devices
such as air conditioners, large fans, large electric motors, radio and TV transmitters, and high
frequency security devices
• Spacious enough to provide sufficient room behind and around the server so that you can
remove AC power from it by unplugging the power cord from the AC inlet filter or wall outlet
• Away from sources of vibration or physical shock
