Safety Guidelines

B

EFORE YOU REMOVE A SERVER COVER, OBSERVE THESE GUIDELINES

1. Turn off all peripheral devices connected to the server.

2. Turn off the server using the power button on the front panel of the
server, and unplug the alternating current (AC) power cord from each
power supply.

3. Label and disconnect all peripheral cables attached to the I/O panel on
the back of the server.

4. Provide some electrostatic discharge (ESD) protection by wearing an
antistatic wrist strap attached to chassis ground of the server—any
unpainted metal surface—when handling components.

Warnings and Cautions

These warnings and cautions apply whenever you remove the side cover of
the server to access components inside the server. Integration of the server
should be done by technically qualified personnel.

before opening it. Otherwise, personal injury or
equipment damage can result.

CAUTIONS

LECTROSTATIC DISCHARGE

E

ESD can damage disk drives, add-in boards, and other
components. We recommend doing all procedures in this
manual only at an ESD workstation. If one is not available,
you can provide some ESD protection by wearing an
antistatic wrist strap attached to chassis ground of the
server—any unpainted metal surface—when handling
components.

be extremely sensitive to ESD and always require careful
handling. After removing a board or module from its
protective wrapper or from the server, place it
component-side up on a nonconductive, static-free surface.
If you place the system board on a conductive surface, the
battery leads may short out. If they do, this will result in a
loss of CMOS data and will drain the battery. Do not slide
a board or module over any surface.

Chapter 1 Server Description

Two spring-loaded captive screws secure the removable metal door behind
the lower plastic front door to the chassis. This door provides proper
air-flow and easy access to the hot-docking bays for hot-swapping hard disk
drives in and out of the system. Both removable side covers are attached to
the chassis with three screws. They provide proper airflow and easy access
to the system board and power supplies. These covers can be secured to the
chassis with padlocks (not provided). Figures 1-1 and 1-2 show the major
system components.

System Security

There are several ways to prevent unauthorized entry or use of the system.

Security with padlocks and alarm switches:

• Secure the side covers and the hot-docking bay metal door to the chassis

by inserting padlocks (not provided) through the holes in the metal tabs

protruding through slots in the covers and door.

• Activate alarm switches for the side covers and hot-docking bay metal

door. These switches transmit alarm signals to the system board.

Software on the system board intercepts these signals and alerts the user

to unauthorized activity.

Security with the Setup utility:

• Set 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 Configuration Utility (SCU):

• Enable the keyboard lockout timer so that the system 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.

• Enable video blanking if using onboard video.

Chapter 1 Server Description

Password Protection

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 system or
run the SCU. If you set both passwords, entering either one lets you boot
the system or enable the keyboard and mouse, but only the administrative
password lets you change the system configuration.

Secure Boot Mode

The secure boot mode allows the system to boot and run the operating
system (OS). However, you cannot use the keyboard or mouse until you
enter the user password.

You can use the SCU to put the system into the secure boot mode. If the
BIOS detects a CD in the CD-ROM drive or a diskette in drive A at boot
time, it prompts you for a password. When you enter the password, the
system boots from the CD-ROM drive or diskette drive and disables the
secure mode.

If there is no CD in the CD-ROM drive or diskette in drive A, the system
boots from drive C and automatically goes into secure mode. All enabled
secure mode features go into effect at boot time.

You can set a hot-key combination to secure the system immediately.

Boot Sequence Control

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 SCU to select each boot device. The default boot
sequence is diskette, hard disk, CD-ROM, and Network.

Boot Without Keyboard

The system can boot with or without a keyboard. Before boot, the BIOS
displays a message whether it has detected a keyboard or not. During
POST, the BIOS automatically detects and tests the keyboard if it’s present.

Power and Reset Button Lock

If enabled by the Setup Utility, the power and reset buttons are disabled
when in the secure mode.

Diskette Write Protection

If the protection feature is enabled with the SCU, diskette writes are

disabled when the system is in the secure mode. Diskette write protection is

only in effect while the system is in the secure mode. Otherwise, write

protection is disabled.

Video Blanking

If enabled with the setup or SCU, the video screen goes blank when the

system is in secure mode.

Power System

The power system in the server may be configured with one, two, or three

360 watt power supplies.

The 360 watt power supply provides sufficient power for an entry level

server. The power supply accepts these input voltage ranges:

• 100-120 VAC at 50/60 Hertz (Hz); 7.7 A maximum current

• 200-240 VAC at 50/60 Hz; 4.4 A maximum current

If a single power supply fails in a redundant power system, the yellow

power supply failure LED on the front panel starts flashing. You can swap

out the faulty supply without shutting down the server.

Server Cooling

Two blowers inside the chassis provide cooling for the processors, memory

modules, and add-in boards. Two more fans may be installed for

redundant cooling. If a fan or blower fails, the server management

subsystem notifies the system board and turns on an LED on the front

panel.

A system with only one power supply includes an auxiliary fan to provide

cooling for the hard drives. A system with multiple power supplies

provides enough cooling without an auxiliary fan.

Peripheral Drive Bays

3.5-inch User Accessible Diskette Drive Bay

The 3.5-inch diskette drive in the vertical 3.5-inch peripheral bay supports
720 KB and 1.44 MB media.

5.25-inch User Accessible Drive Bays

Three 5.25-inch half-height bays provide space for removable media devices
such as tape drives and CD-ROM drives. You can convert any two adjacent

5.25-inch bays to a single full-height bay. We recommend that you do not
use these bays for hard disk drives because they generate EMI, and ESD
susceptibility increases.

3.5-inch Hot-docking Drive Bays

Using industry standard 80-pin SCA connectors, the hot-docking backplane
in the upper bay supports up to five industry standard SCA hard disk
drives. The hot-docking bays accept peripherals that consume up to 11
watts of power and run at a maximum ambient temperature of 55 °C.

You can install an additional hot-docking backplane in the lower
hot-docking bay for five more drives. However, if you do, you must install
an additional power supply in the chassis to support drives in the lower
bay. The upper and lower hot-docking bays, when fully configured with 10
4 GB hard disk drives, provide over 40 GB of hard disk drive space.

The plastic front door on the front of the server covers a removable metal
door. Two spring-loaded captive screws secure the metal door to the
chassis. These doors provide proper air-flow and easy access to the drives
in the upper and lower hot-docking bays. Plastic drive carriers for 3.5-inch
wide by 1-inch high drives allow easy hot swapping of these drives without
shutting down the server.

With the RPX board installed on the system board, RAID software, and
SCSI hard disk drives in the hot-docking bays, you can easily set up RAID
applications.

Onboard RAID

With the RPX board installed on the system board, RAID software, and

SCSI hard disk drives in the hot-docking bays, you can easily set up RAID

applications. A two channel RAID solution can be constructed by installing

an RPX module with RAID firmware resident in the RPX FLASH memory.

The server system supports two types of embedded RAID firmware

packages: I2O compliant and vendor proprietary firmware. The RAID

features are as follows:

• RAID levels 0, 1, 3, 5, 0+1, and JBOD

• Support for hot spares, hot plugs, and user selectable rebuild rate

• Support for multiple rebuilds across separate arrays and multiple

consistency checks

• Write back cache support with battery backup

• Support for up to 2 terabytes per logical array and up to 64 terabytes of

attached disk storage

• Support for SAF-TE and SMART

Server System Board

ISA Expansion Slots

30

One of the ISA connectors shares a common chassis I/O expansion slot with

a PCI connector; you can use either ISA or PCI in the slot, but not both.

The ISA bus operates at up to 8.33 MHz and provides

• 24-bit memory addressing

• Type A transfers at 5.33 MB per second

• Type B transfers at 8 MB per second

• 8- or 16-bit data transfers
