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.  
!
▲
WARNINGS  
SERVER POWER ON/OFF: The power button on the front  
panel of the server does not turn off the AC power. To  
remove AC power from the server, you must unplug each  
AC power cord from each power supply or wall outlet.  
HAZARDOUS CONDITIONS, POWER SUPPLY AND POWER SHARE  
BACKPLANE Hazardous voltage, current, and energy levels  
:
are present inside the power supply and the power share  
backplane. There are no user serviceable parts inside  
them; servicing should be done only by technically  
qualified personnel.

HAZARDOUS CONDITIONS, DEVICES AND CABLES: Hazardous  
electrical conditions may be present on power, telephone,  
and communication cables. Turn off the server and  
disconnect telecommunications systems, networks,  
modems, and each power cord attached to the server  
before opening it. Otherwise, personal injury or  
equipment damage can result.  
CAUTIONS  
!
▲
▲
ELECTROSTATIC DISCHARGE (ESD) AND ESD PROTECTION:  
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.  
ANDLING BOARDS AND MODULES: Boards and modules can  
H
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.  
COOLING AND AIRFLOW: Operating the server with the covers  
removed can damage the server components. For proper  
cooling and airflow, always replace the covers before  
turning on the server.

Server Description 1  
Your system supports symmetrical multiprocessing (SMP) and a variety of  
operating systems. The server comes with both PCI and ISA buses, one  
narrow and two wide SCSI channels, and onboard video. The server board  
set consists of the following:  
•
System board with seven PCI expansion slots, three ISA expansion  
slots, and several embedded controller devices (PCI video, Dual Ultra  
SCSI, Narrow SCSI, and IDE)  
•
•
One or two Pentium II processors  
Memory module with either eight 3.3 V EDO DIMM sockets for up to  
1 GB of memory, or four SDRAM DIMM sockets for 512 MB of memory

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.

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.  
M440LX Server System Product Guide  
27  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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  
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

PCI Expansion Slots  
The seven PCI bus master slots on the system board provide for expansion  
and performance enhancement. One of the PCI connectors shares a  
common chassis I/ O expansion slot with an ISA connector; you can use  
either PCI or ISA in the slot, but not both.  
The PCI bus operates at up to 33 MHz and provides  
•
•
•

Hierarchical bus to maximize connectivity  
PCI Video Controller  
The onboard Cirrus Logic CL-GD54M40 32-bit video graphics accelerator  
contains a super video graphics array (SVGA) controller that is fully  
compatible with these video standards: CGA†, EGA†, Hercules† Graphics,  
MDA†, and VGA. The standard server configuration comes with 512 KB of  
onboard video memory allowing pixel resolutions of up to 1024 x 768 and  
16 colors.  
The SVGA controller supports analog VGA monitors (single and multiple  
frequency, interlaced and noninterlaced) with a maximum vertical retrace  
interlaced frequency of 87 Hz.  
The buffer size of the onboard video memory can be increased from 512 KB  
to 1 MB with one 40-pin 256 K x 16, 60 ns fast-page dynamic random access  
memory (DRAM). 1 MB of DRAM will allow the controller to support  
132-column text modes and high resolution graphics with 1280 x 1024 x 16  
colors. Depending on the environment, the controller displays up to 64,000  
colors in some video resolutions. It also provides hardware accelerated bit  
block transfers (BITBLT) of data.

SCSI Controllers  
The system board includes two wide/ fast-20 SCSI controller chips  
integrated as PCI bus masters. These controllers support:  
•
•
•
•
An 8-bit (narrow SCSI) data path at a data transfer rate of 20 MB/ sec.  
A 16-bit (wide SCSI) data path at a data transfer rate of 40 MB/ sec.  
Data transfer rates of 133 MB/ sec as PCI bus masters.  
The connection of a maximum of seven 8-bit narrow SCSI devices to  
each controller.  
•
The connection of a mixture of up to fifteen 16-bit wide and/ or 8-bit  
narrow SCSI devices to each controller (maximum of seven 8-bit narrow  
devices).  
The system board also includes a narrow SCSI controller integrated as a PCI  
bus master. You can connect a maximum of seven narrow SCSI devices to  
this controller.  
The SCSI controllers provide active negation outputs, controls for external  
differential transceivers, and a disk activity output. Active negation outputs  
reduce the chance of data errors by actively driving both polarities of the  
SCSI bus and avoiding indeterminate voltage levels and common-mode  
noise on long cable runs. The SCSI output drivers can directly drive a  
48 milliampere (mA), single-ended SCSI bus with no additional drivers.

Server Management  
During normal operation, server management receives information about  
server status and monitors power supply voltages and operating  
temperature. If server management software determines that the server is  
not operating within specified limits, the software attempts to notify a  
supervisor or an administrator of the server’s condition. Server  
management features are implemented with the following system board  
microcontrollers.  
Baseboard Management Controller (BMC) does the following:  
•
•
•
•
•
Monitors the processor power supply voltage levels  
Monitors then processor thermal trip and internal error signals  
Monitors the fan sensors  
Manages two I2C thermal sensors located near each processor  
Manages fault resilient booting (FRB) that controls the ability to boot the  
server using either processor in the event of a catastrophic processor  
failure  
Front Panel Processor (FPP) on the system board does the following:  
•
•
Manages power, reset, and front panel NMI buttons  
Monitors all power control sources on the front panel, server manager  
module, PIIX4, and RTC power control signals  
An EEROM associated with the system board temperature sensor contains  
the following:  
•
•
•
•
•
Chassis ID  
System board ID  
Power state  
System board temperature  
Intrusion detection during both power on and off conditions

Pentium II Processor  
The system board has two connectors for Pentium II processors. The  
secondary processor requires a plug-in DC to DC converter on the system  
board to provide power to the processor.  
In a symmetric multiprocessor (SMP) environment, all processors are equal  
and have no preassigned tasks. Distributing the processing loads between  
both processors increases system performance. This is particularly useful  
when application demand is low and the I/ O request load is high. In an  
SMP environment, both processors share a common bus, the same interrupt  
structure, and access to common memory and I/ O channels. The SMP  
implementation conforms to the Multiprocessor Specification Version 1.4.  
Memory Module  
The memory module has eight DIMM sockets. The module supports from  
16 MB to 1 GB of extended data out (EDO) ECC memory 3.3 V 60 ns  
DRAMs, mounted on JEDEC DIMMs. You may install mixed sizes and  
types of DRAM DIMMS in the eight memory banks; however, their speeds  
must be the same. The BIOS automatically detects and initializes the  
memory array.  
ECC memory detects and corrects single-bit errors from DRAM in real time,  
allowing your system to function normally. It detects all double-bit errors  
but does not correct them; it also detects all three-bit and four-bit adjacent  
errors in a DRAM nibble but does not correct them. When one of these  
multiple-bit errors occurs, the PAC generates an SERR (system error) that  
usually halts the system. ECC is calculated on a 64 bit wide memory basis.

Configuration Utilities  
•
Symbios SCSI Utility is used to configure/ view the settings of the SCSI  
host adapters and devices in the system. See page 76.  
•
System Configuration Utility (SCU) is on the Configuration Software  
CD shipped with the system. See Chapter 2, “Installing The System,”  
for instructions on creating an SCU diskette. See page 51.  
•
BIOS Setup Utility is stored in both flash memory and the battery-  
backed memory of the real-time clock (RTC) on the system board. See  
page 59.  
If the diskette drive is disabled or improperly configured, use Setup to  
enable it so that you can run the SCU. If necessary, disable the drive after  
exiting the SCU. Information entered using the SCU overrides any entered  
using Setup.

WARNING  
The power button on the front panel of the system does  
not turn off the AC power. To remove AC power from the  
system, you must unplug the AC power cord from each  
power supply or wall outlet.  
Turn on the video monitor and system. After a few seconds the power-on  
self test (POST) begins.  
Each time you turn on the system the power LED on the front panel turns  
on and the POST starts running. The POST checks the system board,

When to Use the System Configuration Utility  
The SCU lets you do the following:  
•
•
•
•
Add and remove boards  
Change the system configuration settings  
Save the system configuration  
View switch and jumper settings on the boards in the system  
To install or remove an ISA add-in board in the system, you must run the  
SCU to reconfigure the system. Running the SCU is optional for a PCI  
add-in board.  
The SCU is PCI-aware and complies with the ISA Plug and Play  
specifications. The SCU works with any compliant configuration (.CFG) or  
overlay (.OVL) files supplied by peripheral device manufacturer.  
The system board comes with .CFG and .OVL files. The .CFG file describes  
the board’s characteristics and the system resources that the board requires.  
The configuration registers on PCI and ISA Plug and Play add-in boards  
contain the same type of information that is in a .CFG file. However, some  
ISA add-in boards do come with a .CFG file.  
The SCU uses the information provided by the .OVL and .CFG files,  
configuration registers, NVRAM, and the information that you enter, to  
specify a system configuration. It configures the system by writing the  
configuration information to flash memory.  
The SCU stores most of the configuration values in the battery-maintained  
memory (NVRAM) of the real-time clock (RTC), and it stores the rest of the  
values in flash memory. These values take effect when you boot the system.  
The POST checks the values against the actual hardware configuration; if  
they do not agree, it generates an error message. You must then run the  
SCU to specify the correct configuration before the system boots.  
The SCU always updates a checksum for both areas so that the BIOS can  
detect any potential data corruption before the actual hardware  
configuration takes place. If the data is corrupted, the BIOS requests that  
the user configure the system before it can boot.  
Pressing <F1> on the keyboard, in response to the BIOS prompt during the  
POST, activates the BIOS Setup Utility.

When to Run the BIOS Setup Utility  
The Setup utility lets you change the system configuration defaults. It does  
not let you enter or change information about PCI or ISA add-in boards; you  
must use the SCU instead. Setup stores most of the configuration values in  
the battery-backed memory of the RTC; the rest of the values are stored in  
flash memory. The values take effect when you boot the system. The POST  
checks these values against the actual hardware configuration; if they do not  
agree, it generates an error message. You must then run Setup to specify  
the correct configuration.  
You can run the Setup utility with or without an operating system being  
present.  
Since values entered using the Setup utility are overwritten when you run  
the SCU, you should only run Setup under the following conditions:  
•
•
•
To enable the diskette drive  
If you do not have access to a diskette drive  
If you do no want to configure any ISA add-in boards in the system  
Running the Setup Utility

Press F2 key if you want to run SETUP  
Press <F2> to run Setup.

Installing Video Drivers  
After you have configured the system, you can install various video drivers  
to take full advantage of its onboard, integrated Cirrus Logic CL-GD54M40  
super VGA video controller’s enhanced features. The system may not  
operate properly without these video drivers installed.  
For the most current information on which video drivers you need, read the  
README.TXT file on the Display Drivers and DOS Utilities diskette. To  
install drivers from the diskettes, follow the installation instructions in the  
README.TXT file.  
The video drivers are on the Configuration Software CD. For instructions  
on creating Video diskettes, see Chapter 2, “Installing The System.”  
To install these video drivers, do this:  
1. Fully configure the system. (This may include adding video DRAM  
buffer memory, application software, or new ISA or PCI add-in boards.)  
2. Insert disk 1 of the video drivers and utilities for MS-DOS and  
Windows† into drive A.  
3. At the DOS command prompt, type A:install and press <Enter>.  
4. Follow the directions on the monitor to install the video drivers.  
If the system does not operate as described in this chapter, follow the  
instructions in Chapter 10, “Solving Problems.”  
Installing SCSI Drivers  
The SCSI drivers are on the Configuration Software CD. For instructions on  
creating SCSI diskettes, see Chapter 2, “Installing The System.” To install  
the SCSI drivers, follow the instructions in the README.TXT file on the  
first diskette.

Covers  
The system comes with the following removable covers:  
•
•
The left side cover provides access to the system board and fans.  
The right side cover provides access to the power supplies, power-  
sharing board, 3.5-inch vertical drive bay, 5.25-inch horizontal  
peripheral bays, and SCSI hot-docking backplanes.  
•
•
The top cover provides access to the front panel board. You must  
remove both side covers before you can remove the top cover.  
The plastic front cover provides access to the front of the chassis and the  
5.25-inch horizontal peripheral bays. You must remove both side covers  
and the top cover before you can remove the front cover.  
•
The snap-in plastic peripheral bay cover provides access to the 5.25-inch  
horizontal peripheral bays without the need to remove other covers.  
CAUTION  
!
▲
▲
For proper cooling and airflow, do not operate the system  
with the covers removed. Always replace them before  
turning on the system.  
Removing a Side Cover  
The side covers are interchangeable. See Figure 4-1.  
1. Observe the warnings and cautions on page 3, “Safety Guidelines.”  
2. Remove the three screws from the side cover, and save them.

Replacing a Side Cover  
The identical side covers can be installed on either side of the system. See  
Figure 4-1.  
1. Before replacing the side cover, make sure you did not leave any tools  
or loose parts inside the chassis.  
2. Ensure that add-in boards are firmly seated in their respective slots,  
retaining brackets are firmly secured with screws tightened to  
6.0 inch-pounds, and interior cables are properly connected.  
3. Position the side cover over the chassis so that the metal tabs across the  
top and bottom edges of the cover align with the slots in the top cover  
and bottom edge of the chassis. Slide the cover toward the front of the  
system so that the tabs along the front edge of the cover firmly engage  
in the front slots of the chassis.

Add-in Boards  
The system board provides seven PCI bus master slots and three ISA bus  
master slots. They accept any add-in PCI and ISA boards. One PCI  
connector shares a common chassis I/ O expansion slot with an ISA  
connector; you can use either PCI slot or ISA in the slot, but not both.  
CAUTIONS  
!

Back-up Battery  
The lithium battery on the system board powers the real-time clock (RTC)  
for up to 10 years in the absence of power. The RTC contains 256 bytes of  
general purpose RAM that stores the system BIOS configuration  
information, clock registers, and general purpose control registers. When  
the battery starts to weaken, it loses voltage, and the system settings stored  
in CMOS RAM in the RTC (for example, the date and time) may be wrong.  
Contact your sales representative or dealer for a list of approved  
replacement devices and available service.

SCSI Backplane and Drives:  
Hot-swapping and Configuring  
5
This chapter tells how to configure the SCSI backplane and install hot-swap  
SCSI hard disk drives.  
Warnings and Cautions  
Before you remove the system covers to work inside it, observe the  
warnings and cautions provided for your safety on page 3, “Safety  
Guidelines.”  
System integration should be done by technically qualified personnel.  
Tools and Supplies You Need  
•
•
•
•
Phillips (cross-head) screwdriver (#1 bit and #2 bit)  
Jumper removal tool  
Pen or pencil  
Antistatic wrist strap (recommended)  
Hot-docking Bays  
The plastic front door covers a removable metal door that is secured to the  
chassis with two screws. Plastic drive carriers for 3.5-inch wide by 1-inch  
high drives allow easy hot-swapping of drives without shutting down the  
system.  
The upper and lower bay each have a separate backplane. Each backplane  
uses industry standard 80-pin SCA connectors to support up to five  
industry standard wide/ fast-20 SCSI III SCA hard disk drives. The bays  
accept peripherals that consume up to 11 watts of power and run at a  
maximum ambient temperature of 65 °C.  
By installing an RPX board and appropriate software on the system board  
and SCSI hard disk drives in the hot-docking bays, you can easily set up  
Redundant Array of Inexpensive Disks (RAID) applications.

SCSI Hot-docking Backplane  
The hot-docking backplane provides the following:  
•
•
Five SCA connectors for SCA-compatible SCSI drives  
Power control for each drive, including automatic slot-power-down  
upon removing a drive  
•
•
•
•
Signal for a fault indicator on the front panel for each drive  
Internal I2C bus  
+12 V connector for a fan with tachometer  
Local I2C-based temperature sensor  
The SCSI hot-docking backplane provides control signals and power for five  
wide/ fast 3.5-inch SCA SCSI hard disk drives. The backplane receives  
control signals from the Symbios SCSI controller on the system board  
through a cable connected to the wide SCSI connector on the backplane.  
The backplane gets power from the power system through cables connected  
to the two power connectors.  
The drives get their control signals and power from the SCA connectors on  
the backplane.  
The fault indicators on the front panel indicate failure status for each drive  
in the bay. These indicators get their signals through a cable connected to  
the front panel connector on the backplane.  
The temperature sensor on the backplane provides temperature information  
to other devices in the system through enclosure service messages.  
The backplane power control provides powering down of a drive when a  
failure is detected and reported to the SCSI bus. When a new drive is  
inserted, the power control waits a short time for the drive to become fully  
seated and then applies power to the drive.  
Configuration Options  
The hot-docking backplane contains only one configuration jumper: J8, the  
internal/ external jumper.  
A jumper is a small plastic-encased conductor—shorting plug—that slips  
over two jumper pins.  
M440FX Server System Product Guide

Download from Www.Somanuals.com. All Manuals Search And Download.  
Internal/External (INT/EXT) Jumper J8  
When this jumper is in the “INT” position—jumper on pins 1 and 2 default  
setting—the backplane assumes it is operating in an “internal” peripheral  
bay in the chassis.  
When this jumper is in the “EXT” position—jumper on pins 2 and 3—the  
backplane assumes it is operating in an “external” peripheral bay in a  
peripheral expansion chassis. This option is not available.  
SCSI ID Configuration Options  
The SCSI chip on the hot-docking backplane uses the SAF-TE protocol to  
communicate with the system board. This chip uses SCSI ID 6; therefore,  
other SCSI devices cannot use this address.

3. Remove the right side cover as described in Chapter 4, “Working Inside  
Your System.”  
4. The jumpers are parallel with the backplane surface as shown in  
Figure 5-3. Looking into the right side of the system, between the back  
of the bay and the backplane, J10 is the top jumper and J9 is the next one  
down. To remove a jumper, use a jumper removal tool.  
5. To install a jumper, position it over the two pins for the desired setting  
and press down firmly. Be careful not to bend the pins.  
6. Replace the right side cover as described in Chapter 4, "Working Inside

Memory Module Resources  
The memory module contains eight DIMM sockets for installing memory. It  
supports from 16 MB to 1 GB of EDO ECC 3.3 V 60 ns DRAM, mounted on  
JEDEC DIMMs. You may install mixed sizes and types of DIMMs in the  
eight memory banks; however, their speeds must be the same. Always  
install the DIMMs in sequence by starting with bank 0 (socket J1, closest to  
the system board), then bank 1 (socket J2), and so on with bank 7 (socket J8)  
as the last one.  
To avoid potential memory problems, use only DIMMs from JEDEC-  
compatible manufacturers that have been tested for compatibility with the  
memory module. Contact your sales representative or dealer for a list of  
approved DIMMs.  
ECC memory detects and corrects single-bit errors from DRAM in real time,  
allowing your system to function normally. It detects all double-bit errors  
but does not correct them; it also detects all three-bit and four-bit adjacent  
errors in a DRAM nibble but does not correct them. When one of these  
multiple-bit errors occurs, the PMC generates an SERR (system error) which  
usually halts the system. ECC is calculated on a 64 bit wide memory basis.  
The system supports both base (conventional) and extended memory. Base  
memory is located at addresses 00000h to 9FFFFh (the first 640 KB).  
Extended memory begins at address 0100000h (1 MB) and extends to  
FFFFFFFFh (4 GB), which is the limit of addressable memory. The top of  
physical memory is a maximum of 1 GB.  
Some operating systems and application programs use base memory; for  
example, MS-DOS, OS/ 2†, and UNIX. Other operating systems use both  
conventional and extended memory; for example, OS/ 2 and UNIX.  
MS-DOS does not use extended memory; however, some MS-DOS utility  
programs such as RAM disks, disk caches, print spoolers, and windowing  
environments use extended memory for better performance.

Installing DIMMs  
CAUTIONS  
!
▲
▲
Use extreme care when installing a DIMM. Applying too  
much pressure can damage the socket slot. DIMMs are  
keyed and can be inserted in only one way.  
Mixing dissimilar metals may cause failures. Install DIMMs  
with gold-lead alloy plated edge connectors only in  
gold-lead alloy plated sockets.  
See Figures 6-2 and 6-3.  
1. Observe the warnings and cautions on page 3, “Safety Guidelines.”  
2. Remove the left side cover and memory module as described in  
Chapter 4, "Working Inside Your System."  
3. Hold the module only by its edges, being careful not to touch its  
components or gold edge connectors, and place it processor-side up on  
an antistatic surface.  
4. Remove a DIMM from its antistatic package by holding the DIMM only  
by its edges.  
5. Beginning with bank 0 (Figure 6-2), socket J1, orient the DIMM so that  
the two notches in the bottom edge of it align with the keyed DIMM  
socket.  
6. Insert the bottom edge of the DIMM into socket J1, and press down  
firmly on the DIMM until it seats correctly (Figure 6-3).

This chapter describes the power system and explains how to calculate  
power consumption.

An entry level power system typically limits the server configuration to  
dual processors, 1 GB memory, five hard drives, and total power dissipated.  
A maximum level power system provides power for fully configured  
servers.  
Each power supply has a built-in fan and its own power cord. For servers  
with redundant power systems, the loss of a single power supply will not  
affect the operation of the server.

Redundant mode  
240 VA limit  
The current sensing feature of the power share backplane shuts down the  
entire power system if any single output from the backplane to the system  
board or peripherals exceeds 240 VA. Current sensing limits the energy  
supplied by the power share backplane to levels generally accepted as  
operator accessible areas—less than 240 VA for the CSA Level 3 category—  
without the use of interlocks.  
If a power supply fails in a redundant power system, the yellow power  
supply failure LED on the front panel starts flashing. The power supply can  
be easily replaced without shutting down the system. The power supply is  
inserted through the back of the chassis and held in place with four screws.

Power System Control Signals  
Power Enable/Disable (PON)  
The PON control signal originates on the system board, and it is routed  
through the power share backplane microcontroller. If the +5 V and +12 V  
power going to the system board or the peripherals exceeds 240 VA, the  
backplane microcontroller will disassert the PON control going to each  
power supply (J4, J6, and J9). This signal is used to enable and disable the  
power supplies.  
Remote Sense Connections  
Individual remote sense outputs are provided to each +5 V and +3.3 V  
power supply section. Remote voltage sense for +5 V and +3.3 V is done on  
the system board. The +5 V and +3.3 V remote sense lines are routed  
through the power share backplane and connect to the current sense  
circuitry.  
The +12 V is not sensed remotely. Instead, it is sensed on the power share  
backplane.  
Load Share Connection  
In systems with redundant power systems, the +5 V, +3.3 V, and +12 V  
outputs from each power supply are routed through the power share  
backplane. The current from each power supply output is monitored with a  
current monitoring circuit. This current’s value is used to adjust the load  
share of each power supply output.  
Output Power Connections  
The +12 V, +5 V, and +3.3 V power outputs are routed through J1 to the  
system board power connector. The +12 V and +5 V power outputs are also  
routed through J5 to the peripheral power connector.  
The -12 V, -5 V, and +5 V standby outputs are joined together through an  
isolation circuit and connected to the system board through connector J1.

Power Good Circuit  
The power good circuit looks at the levels of the power good (PGOOD)  
signals. When the backplane PGOOD circuit senses a PGOOD signal, a  
system PGOOD is asserted after an approximately 550 ms delay. Only a  
single PGOOD signal assertion will cause the assertion of the system  
PGOOD.  
VA Monitor Circuit  
The total supply current that forms part of the load sharing circuit monitors  
+3.3 V as well as +5 V and +12 V on the system board. The microcontroller  
determines the current supplied to the system board by subtracting the  
peripheral current from the total current.  
If either the system board power or peripheral power exceeds 240 VA, the  
backplane microcontroller disables the supply outputs by disasserting PON.  
The following table shows the maximum available current to each of the  
system connections. Resetting the circuit requires unplugging all of the  
power supplies.

The maximum current number shown is the sum of the currents from all  
supplies.  
I²C Communication Circuit  
The power share backplane microcontroller communicates with a similar  
device on the system board through an I2C data link. This link reports the  
number of power supplies in the server, current and power to the system  
board and peripherals, and power supply status. The I2C signals are routed  
through J2 to the system board.

Chapter 7 Power System

System Current Monitor  
The system current monitor on the power share backplane sends a power  
usage report to the server via the I2C communications bus. The backplane  
microcontroller contains analog-to-digital converters that monitor DC  
voltage levels supplied by the current sense circuits. They represent the  
current load on the +3.3 V output from the system board and the +5 V and  
+12 V load at both the system board and the peripheral bays.  
If either the +5 V or +12 V load from the system board or the peripherals  
goes beyond the CSA Level 3 requirement of 240 VA, the power is shut off  
immediately by disserting PON. It is impossible to draw 240 VA from the  
3.3 Volt power supply output even when three supplies are installed in the  
server. The following table shows the maximum current allowed by each  
voltage output for a server with three 360 watt power supplies.

+5 V  
33 A  
96 A  
48 A  
+12 V  
36 A (or 48 A for 12 ns maximum)  
20 A  
A voltage level within the range of 0 to 5 V is supplied by the current sense  
circuits on the power share backplane. The current limit threshold is set to  
44 A ±4 A for each +5 V channel and 16 A +4 A for each +12 V channel.  
Power Supply FAULT  
Each power supply provides a power good (PGOOD) signal that is asserted  
high. If a power supply fails, its PGOOD signal goes low. The power  
supply outputs are enabled through assertion of the PON signal. If the  
PGOOD signal goes low, indicating a power bad condition while PON is  
asserted, a FAULT is generated and applied to one of the FAULT inputs of  
the backplane microcontroller.  
Power Supply Presence DETECT  
The DETECT signal senses the number of power supplies (operational or  
not) in the server. Each power supply presents a grounding connection to  
one of the backplane microcontroller input pins to show that a power  
supply is present. If a power supply is not present, the backplane  
microcontroller input pin will be pulled high through a pull-up resistor to  
+5 V standby.

Server Current Usage  
As an overall current usage limitation on the power supply, do not exceed  
its maximum output capacity of 32 amperes at +5 volts (160 watts) and 11  
amperes at +3.3 volts (36.3 watts). The combined power output for the +5  
and +3.3 volt outputs should not exceed 178 watts.  
The maximum current allowed at +5 volts for each PCI and ISA slot on the  
system board is 2 amperes (10 watts).  
The cooling efficiency varies per slot; therefore, ensure that adequate  
cooling is available in the target slot—especially in an expansion slot  
drawing more than 2.0 amperes.

Calculating Power Usage  
Use the worksheets in Tables 7-1 and 7-2 to calculate the total DC power  
used by your system configuration.  
The documentation that comes with each add-in board and peripheral  
device should specify its current and voltage requirements.  
To calculate the total combined wattage for your system, do this:  
1. List the current for each board and device in the appropriate voltage  
level column in Table 7-2.  
2. Add the currents in each column of Table 7-2, and enter the total current  
for each column in Table 7-1.  
3. Multiply the voltage by the total current to get the total wattage for each  
voltage level.  
4. Add the total wattage for each voltage level to arrive at a total  
combined power usage on the power supply.  
Note  
✏
The total combined wattage for your system configuration  
must be less than 360 watts.

Fault Resilient Booting (FRB)  
The jumper on the J3J1 FRB ENA pins allows the system to boot from  
processor 1 if processor 0 fails. Moving the jumper to the DIS pins lets the  
system boot only from processor 0.  
To boot only from processor 0, do this:  
1. Observe the precautions on page 3, “Safety Guidelines.”  
2. Remove the left side cover as described in Chapter 4, “Working Inside  
Your System.”  
3. Move the jumper on the J3J1, FRB from the ENA pins to the DIS pins.  
4. Replace the left side cover, and connect the power cord(s) to the system.  
5. Turn the system on, and wait for POST to complete; for instructions on  
running POST, see Chapter 3, “Configuring The System.”  
6. Run the SCU to configure your system. For information on running the  
SCU, see Chapter 3, "Configuring The System."  
Flash Memory  
The jumper on the J3J1, Flash PROG pins applies +12 V power to the VPP  
pin on the flash memory device. This allows you to update the BIOS in  
flash memory with a special Flash Memory Update Utility. Moving the  
jumper to the PROT pins protects the contents of flash memory.  
For a copy of the latest system BIOS release, contact your dealer or sales  
representative.  
Updating the BIOS  
Before you can update the system BIOS from the Flash Memory Update  
Utility diskette, you must make it MS-DOS bootable. You must have either  
MS-DOS version 5.00 or 6.00 (or greater) installed on C:\ DOS.  
To prevent accidentally installing a BIOS for a different type of system, the  
update utility insures that the BIOS matches the target system.  
CAUTION  
!
▲
▲
To avoid memory conflicts, do not run the update utility  
with extended memory managers.

To update the BIOS, do this:  
1. Observe the precautions on page 3, “Safety Guidelines.”  
2. Insert the update diskette into drive A, and turn on the monitor and  
system. The update process starts automatically when the system  
boots. Follow the screen prompts.  
3. When the update process completes, remove the diskette, and press  
reset. Wait for POST to complete; for instructions on running POST, see  
Chapter 3, “Configuring The System.”  
4. If you want to protect the contents of flash memory, turn the system off  
and remove the left side cover as described in Chapter 4, “Working  
Inside Your System.”  
5. Move the jumper on the J3J1, Flash PROG pins to the PROT pins to  
write protect the flash memory device.  
6. Replace the left side cover, and connect the power cord(s) to the system.  
Note  
✏
If the system BIOS becomes corrupted during the update  
process—for example, a power outage occurs—follow the  
“Recovering the BIOS” procedure on page 182.  
CPU Speed  
To set the processor speed, do this:  
CAUTION  
!
▲
▲
Over-clocking the processor may damage it and your data.  
1. Observe the precautions on page 3, “Safety Guidelines.”  
2. Remove the left side cover as described in Chapter 4, “Working Inside  
Your System.”  
3. Move the jumper on the J2J1, CPU Speed PROT pins to the Enable pins  
to activate the CPU Speed Setting field in the BIOS Setup Utility.  
4. Replace the left side cover, and connect the power cord(s) to the system.  
5. Run the BIOS Setup Utility as described in Chapter 3, “Configuring The  
System.”  
6. Select the proper speed for your processor.  
7. Repeat step 2 above.

Boot Option  
Moving the boot option jumper on the J2J1, Boot Opt NOR pins to the  
REC pins enables the BIOS flash memory special recovery mode. The  
system BIOS can be corrupted, for example, when the update procedure is  
aborted due to a power outage. However, flash memory contains a  
protected area that cannot be corrupted. Code in this area is used to boot  
the computer from drive A when the BIOS has been corrupted. After  
booting, the Flash Memory Update Utility is used to automatically recover  
the system BIOS from the BIOS recovery files on the diskette.  
Note  
✏
If you have mapped the BIOS of an add-in board to any part  
of the E0000H address range, you must either map it to  
another area before completing a recovery procedure or  
physically remove the board from the system. You do not  
have to remove add-in boards for normal BIOS updates.  
Recovering the BIOS  
To recover the BIOS, do this:  
1. Observe the precautions on page 3, “Safety Guidelines.”  
2. Remove the left side cover as described in Chapter 4, “Working Inside  
Your System.”  
3. Move the jumper from the J2J1, Boot Opt NOR pins to the REC pins to  
allow the system to boot from the recovery BIOS.  
4. Replace the left side cover, and insert the Flash Memory Update Utility  
diskette in drive A.  
5. Connect the power cord(s) to the system, and turn it on. After the  
system boots, the speaker emits a single beep and the recovery process  
starts—it takes about three minutes. When the recovery process  
completes, the speaker emits two beeps.  
While in the recovery mode, there is no screen display on the  
monitor. The keyboard is disabled as the system automatically  
recovers the BIOS. The following beep codes describe the  
recovery status.

Initial System Startup  
Problems that occur at initial system startup are usually caused by incorrect  
installation or configuration. Hardware failure is a less frequent cause.  
Checklist  
❑ Are all cables correctly connected and secured?  
❑ Are the processor modules fully seated in their slots on the system  
board?  
❑ Are all add-in ISA and PCI boards fully seated in their slots on the  
system board?  
❑ Are all jumper settings on the system board correct? For information,  
see Chapter 8, "System Board Jumpers."  
❑ Are all jumper and switch settings on add-in boards and peripheral  
devices correct? To check these settings, refer to the manufacturer’s  
documentation that comes with them. If applicable, ensure that there  
are no conflicts—for example, two add-in boards sharing the same  
interrupt.  
❑ Are all DIMMs on the memory module installed correctly? Refer to  
Chapter 6, "Server Resources," for installation instructions.  
❑ Are all add-in boards and peripheral devices installed correctly? Refer  
to Chapter 4, "Working Inside Your System."  
❑ If the system has a hard disk drive, is it properly formatted or defined?  
❑ Is the SCSI hot-docking backplane configured and terminated correctly?  
For information about the board, see Chapter 5, “SCSI Backplane and  
Drives: Hot-swapping and Configuring .”  
❑ Are all device drivers properly installed? For information about  
installing drivers, see Chapter 3, "Configuring The System."  
❑ Are the configuration settings made with the SCU correct? For  
information about running the SCU, see Chapter 3, "Configuring The  
System."  
❑ Is the operating system properly loaded? Refer to the operating system  
documentation.  
❑ Did you press the power button on the front panel to turn the server on

❑ Is the system power cord properly connected to the system and plugged  
into a NEMA 5-15R outlet for 100-120 VAC or a NEMA 6-15R outlet for  
200-240 VAC? See "Connecting the Power Cord" in Chapter 2,  
"Installing The System."  
❑ Is AC power available at the wall outlet?  
If these items are correct, but the problem recurs, refer to "Additional  
Troubleshooting Procedures" on page 205.  
Running New Application Software  
Problems that occur when you run new application software are usually  
related to the software. Faulty equipment is much less likely, especially if  
other software runs correctly.  
Checklist  
❑ Does the system meet the minimum hardware requirements for the  
software? Refer to the software documentation.  
❑ Is the software an authorized copy? If not, get one; unauthorized copies  
often do not work.  
❑ If you are running the software from a diskette, is it a good copy?  
❑ If you are running the software from a CD-ROM disc, is the disc  
scratched or dirty?  
❑ If you are running the software from a hard disk drive, is the software  
correctly installed? Were all necessary procedures followed and files  
installed?  
❑ Are the correct device drivers installed?  
❑ Is the software correctly configured for the system?  
❑ Are you using the software correctly?

After the System Has Been Running Correctly  
Problems that occur after the system hardware and software have been  
running correctly often indicate equipment failure. Many situations that are  
easy to correct, however, can also cause such problems.  
Checklist  
❑ If you are running the software from a diskette, try a new copy of the  
software.  
❑ If you are running the software from a CD-ROM disc, try a different  
disc to see if the problem occurs on all discs.  
❑ If you are running the software from a hard disk drive, try running it  
from a diskette. If the software runs correctly, there may be a problem  
with the copy on the hard disk drive. Reinstall the software on the hard  
disk drive, and try running it again. Make sure all the necessary files  
are installed.  
❑ If a software application does not run correctly with the "Boot Speed"  
set to turbo, try setting it to deturbo with Setup.  
❑ If the problems are intermittent, there may be a loose cable, dirt in the  
keyboard (if keyboard input is incorrect), a marginal power supply, or  
other random component failures.  
❑ If you suspect that a transient voltage spike, power outage, or brownout  
might have occurred, reload the software and try running it again.  
(Symptoms of voltage spikes include a flickering video display,  
unexpected system reboots, and the system not responding to user  
commands.)  
Note  
✏
If you are getting random errors in your data files, they may  
be getting corrupted by voltage spikes on your power line.  
If you are experiencing any of the above symptoms that  
might indicate voltage spikes on the power line, you may  
want to install a surge suppresser between the power outlet  
and the server power cord.  
❑ If the problem recurs after you have checked and corrected all the above  
items, refer to "Additional Troubleshooting Procedures" on page 205.  
❑ If you receive any error messages, refer to "Error and Informational  
Messages" on page 213 for an explanation of the messages and  
suggested corrective actions.

Monitoring POST  
See Chapter 3, "Configuring The System."  
Verifying Proper Operation of Key System Lights  
As POST determines the system configuration, it tests for the presence of  
each mass storage device installed in the system. As each device is checked,  
its activity light should turn on briefly. Check for the following:  
❑ Does the diskette drive activity light turn on briefly? If not, refer to  
"Diskette Drive Activity Light Does Not Light" on page 210.  
❑ If a second diskette drive is installed, does its activity light turn on  
briefly? If not, refer to "Diskette Drive Activity Light Does Not Light"  
on page 210.  
❑ If there is a hard disk drive or a SCSI device installed in the system,  
does the drive activity light on the front panel turn on briefly? If not,  
refer to "Hard Disk Drive Activity Light Does Not Light" on page 211.  
Note  
✏
See “Controls and Indicators” in Chapter 2, "Installing The  
System."  
Confirming Loading of the Operating System
