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

S

ERVER 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.

H

AZARDOUS 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.

AZARDOUS 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

E

LECTROSTATIC 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.

H

ANDLING BOARDS AND MODULES

:

Boards and modules can 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.

C

OOLING 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

•

RPX module with one SIMM

†

socket for RAID applications

The chassis contains a 3.5-inch diskette drive, a CD-ROM drive, and, depending on the system configuration, up to three 360 watt power supplies. Three 5.25-inch peripheral bays can house tape back-up drives,

CD-ROM drives, and other mass storage devices. Any two adjacent

5.25-inch bays can be converted into a single full-height bay. The two

3.5-inch hot-docking peripheral bays, when fully configured with 10 hard disk drives, provide over 40 GB of storage. The bays allow hot-swapping drives without shutting down the system.

As your application requirements increase, you can upgrade the system with

•

More powerful processors

•

More memory

•

Other peripheral devices

•

Add-in I/O boards

Chassis

The electro-galvanized metal chassis minimizes electromagnetic interference

(EMI) and radio frequency interference (RFI). It contains

•

Three power supply bays with up to three 360 watt power supplies, depending on the configuration

•

One vertical bay that contains a diskette drive

•

Three standard 5.25-in bays for removable media devices (a CD-ROM drive is in the top bay)

•

Two hot-docking bays; each bay has space for five 1-inch high, 3.5-inch single connector attachment (SCA) SCSI hard disk drives

•

Nine I/O expansion slot covers

•

A control panel

20


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.

Figure 1-4. Security Padlocks


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.


27

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.

28


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.


29

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

•

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

30


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

•

32-bit memory addressing

•

Support for 5 V and 3.3V cards

•

Burst transfers of up to 133 MB per second

•

8-, 16-, or 32-bit data transfers

•

Plug and Play configuration

•

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.


31

Video Modes

The 54M40 provides all standard VGA modes. With 512 KB of video memory, the standard server goes beyond standard VGA support. If necessary, you can install an additional 512 KB of video memory on the system board. The following tables show all supported video modes that use 512 KB and 1 MB of video memory.

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.

IDE Controller

The PIIX4 multifunction device on the system board acts as a PCI-based Fast

IDE controller that supports

•

PIO and IDE DMA/bus master operations

•

Mode 4 timings

•

Transfer rates up to 32 MB/sec

•

Buffering for PCI/IDE burst transfers

•

Master/slave IDE mode

34


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 I

2

C 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


35

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.

• near a grounded, three-pronged power outlet a.

In the United States and Canada, this means a NEMA 5-15R outlet for 100-120 VAC or a NEMA 6-15R outlet for 200-240 VAC.

b. For international sites, this means a three-pronged power outlet applicable for the electrical code of the region.

▲

CAUTION

Ensure that the power service connection is through a properly grounded outlet.

• clean and dust-free

• well ventilated and away from sources of heat

• 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 each power supply or wall outlet

✏

Note

For cooling, airflow, and access to the server, allow about

31 centimeters (12.2 inches) of clearance in back,

60 centimeters (23.6 inches) on each side, and 22 centimeters

(9 inches) in front.

• 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

After Unpacking the Server

Inspect the shipping box for evidence of mishandling during transit. If the shipping box is damaged, photograph it for reference. After removing the contents, keep the damaged box and the packing materials. If the contents appear damaged, file a damage claim with the carrier immediately.

WARNING

The minimum server configuration weighs 29 kg (63 lbs.) and the maximum one weighs 44 kg (97 lbs.). To avoid personal injury, have someone help you move the server.

Save the shipping boxes and packing materials to repackage the server in the event you decide to move it to another site.

Installing the Pentium II Processor

The server is shipped without the processor module installed on the system board. Turn to Chapter 4, “Working Inside Your System,” and follow the instructions for installing the processor module. Before you install the module in your server, observe the warnings and cautions provided for your safety on page 3, “Safety Guidelines.”

Installing the Memory Module

The server is shipped without the memory module installed on the system board. Turn to Chapter 4, “Working Inside Your System,” and follow the instructions for installing the memory module. Before you install the module in your server, observe the warnings and cautions provided for your safety on page 3, “Safety Guidelines.”

42


Connecting Peripheral Devices

If your system normally operates without a monitor or keyboard—for example, as a network server—you must install them to configure the system. You may remove them after running the SCU. For information about running this utility, see Chapter 3, “Configuring The System,”.

Connect your keyboard, mouse, monitor, and other peripheral devices after installing all internal options and replacing the side cover. See Figure 2-1.


Before connecting peripheral devices to the server, observe the warnings and cautions provided for your safety on page 3, “Safety Guidelines.”

Server integration should be done by a qualified technical person.

Keyboard

Checking the Power Cord(s)

WARNING

Do not attempt to modify or use a supplied AC power cord if it is not the exact type required.

If a power cord supplied with the system is not compatible with the AC wall outlet in your region, get one that meets the following criteria:

•

The cord must be rated for the available AC voltage and have a current rating that is at least 125% of the current rating of the system.

•

The connector that plugs into the wall outlet must be a grounding-type male plug designed for use in your region. It must have certification marks showing certification by an agency acceptable in your region.

•

The connector that plugs into the AC receptacle on the system power supply must be an IEC 320, sheet C13, type female connector.

•

In Europe, the cord must be less than 4.5 meters (14.76 feet) long, and it must be flexible <HAR> (harmonized) or VDE certified cordage to comply with the system's safety certifications.

Turning on Your Server

WARNINGS

Ensure that the line voltage selector switch on each power supply is set to the correct line source voltage (see page 42). If the setting is incorrect, the power supply will be damaged when you plug the power cord into an AC outlet.

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 the AC power cord from each power supply or wall outlet.

1. Make sure all external devices, such as a monitor, keyboard, and mouse

(optional) have been connected.

2. Remove drive protection cards (if present) from the diskette and tape drives.

3. Turn on your video monitor.


45

4. Plug the female end of each AC power cord into each input receptacle on the back of the chassis (your server may be configured with one, two, or three power supplies).

5. Plug the male end of the cord into a grounded, three-pronged power outlet. (Repeat for each power supply in the server.)

6. If the server doesn’t come on when you plug it into the AC outlet, press the power button (Figure 2-2).

7. Verify that the power-on light on the front panel is lit. After a few seconds POST begins. See “Power-on Self-Test.”

Configuring The System

3

This chapter tells how to run the configuration utilities and install video drivers.

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 batterybacked 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.


49

Power-on Self-Test

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, processor, memory, keyboard, and most installed peripheral devices.

During the memory test, the POST displays the amount of memory that it is able to access and test. Depending on the amount installed on the memory module, the test may take several minutes to complete.

These screen prompts and messages appear after the memory test:

Press F2 key if you want to run SETUP

If you do not press <F2>, the boot process continues, and this message appears:

Press Ctrl C to start configuration Utility!

If you have installed SCSI devices in the system, press <Ctrl+C>. When the utility appears, follow the instructions on the monitor to configure the onboard SCSI host adapter settings and run the SCSI disk utilities. See

“Using the Symbios SCSI Utility” on page 76.

50

Chapter 3 Configuring The System

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.


51

How to start the SCU

Before you can run the SCU from a diskette, you must copy the SCU from the Configuration Software CD to a DOS bootable diskette. For instructions on creating an SCU diskette, see Chapter 2, “Installing The System.”

1. Turn on the video display monitor and system.

2. There are three ways to start the SCU.

•

After creating an SCU diskette from the CD:

Insert the

System Configuration Utility Disk in drive A, and press the reset push-button switch or <Ctrl+Alt+Del> to reboot the system from the diskette.

•

After installing the operating system:

Insert the System

Configuration Utility Disk in drive A, and copy it to a directory on the hard drive. While in the directory, type

AMISCU

and press <Enter>.

•

From diskette after installing the operating system:

Insert the System Configuration Utility Disk in drive A. At the

MS-DOS

†

prompt, type

a:

and press <Enter> to change to drive A. Type

AMISCU

and press <Enter> to start the SCU.

When you see this message:

MS-DOS Startup Menu

-------------------------------

1. Execute AMISCU

2. Execute AMISCU for system with PNP OS

If the operating system in the system supports Plug and Play add-in boards, press <2> to start the SCU. If not, press <1> to start it.

3. When the SCU title appears on the screen, press <Enter> to continue.

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

Reset the system. When you see this message:

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.

WARNING

If the system has been running, any installed processor and heat sink on the processor board(s) will be hot. To avoid the possibility of a burn, be careful when removing or installing system board components that are located near processors.

The following warning and translations are required by specific certifying agencies to be printed immediately adjacent to the procedure for removing the real-time clock.

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.

Hot-swapping a SCSI SCA Hard Disk Drive

A bank of 10 yellow LEDs on the front panel monitors the drive status of each drive in the upper and lower hot-docking bays. When a yellow LED is on continuously, it is okay to hot-swap (replace) a bad drive with a good one. You do not need to shut the system down to hot-swap a drive.

See Figure 5-2.

1. Open the plastic front door of the system.

2. If you installed a padlock on the metal door to the bays, unlock the padlock and remove it.

3. Loosen the two captive, spring loaded screws securing the metal door to the chassis, and open the door.

4. Check the two banks of yellow LEDs on the front panel to determine which drive is bad. Grasp the plastic drive carrier and pull it toward you to disengage the drive connector from the backplane connector.

5. Squeeze the tabs on the carrier toward each other, and carefully slide the bad drive forward out of the bay. Place the drive on an antistatic surface.

6. Position the new plastic carrier and drive assembly so that it engages the bay guide rails.

7. Gently push the drive into the bay until it docks with the backplane connector and snaps into place.

8. Gently close the metal door, and secure it to the chassis with the two captive, spring loaded screws.

9. For security and to prevent unauthorized access to the bays, insert a padlock through the metal loop protruding through the door and lock it.

10. Close the lower plastic front door of the system.

138


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 I

2

C bus

•

+12 V connector for a fan with tachometer

•

Local I

2

C-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.


139

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.

See Figure 5-3.


2. Turn the system off with system power push-button on/off switch on the front panel, and unplug each AC power cord from the power supply or wall outlet.

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

Your System."

7. Plug the AC power cord of each power supply into a separate wall outlet on a dedicated AC branch circuit to avoid overloading a single branch circuit.

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 JEDECcompatible 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.



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).

System Board Resources

Video Memory DRAM

The system board comes with 512 KB of onboard video memory. Increasing the video memory buffer size to 1 MB with a 40-pin 256 K x 16, 60 ns fast-page DRAM allows 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.

✏

Note

DRAMs from only certain manufacturers have been tested for compatibility with the system. Contact your dealer or sales representative for a list of approved manufacturers and their devices.

Power System

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

Power System Configurations

The server contains a modular power system that may be configured with one, two, or three 360 watt power supplies.

Configuration level

Entry

3

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.


163

A redundant power system uses a power share backplane to distribute power to the server. The backplane implements these server management features:

•

I

2

C bus

•

Power supply failure

•

Maximum current

•

Current usage

•

Number of power supplies installed in the server’s power system

•

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.

Chapter 7 Power System

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.


165

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 I

2

C 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 I

2

C signals are routed through J2 to the system board.

166


System Current Monitor

The system current monitor on the power share backplane sends a power usage report to the server via the I

2

C 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.

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.

The chassis contains alarm switches that get activated if a cover is removed.

To bypass the chassis intrusion switches, 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 J3J1, Chassis INTR Detect 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."

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:



Your System.”

3. Move the jumper on the J3J1, FRB from the ENA pins to the DIS pins.


5. Turn the system on, and wait for POST to complete; for instructions on running POST, 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.

180


To update the BIOS, do this:


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.


✏

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.



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.


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.

8. Move the jumper on the J2J1, CPU Speed Enable pins to the PROT pins.

9. Repeat step 4 above.


181

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:



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.

182


Beep Code

Continuous series of low beeps

Message

Successful completion, no errors.

The system could not boot from the diskette. The diskette may not be bootable.

The wrong BIOS recovery files are being used and/or the flash memory jumper is in the wrong position.

6. Turn the system off, disconnect the power cord(s) from the system, and remove the left side cover.

7. Move the jumper from the REC pins to the NOR pins to enable the normal boot mode.

8. Replace the left side cover, remove the diskette from drive A, and connect the power cord(s) to the system.

9. After running the special recovery mode, run the SCU to specify a new password. For information on running the SCU, see Chapter 3,


Password

The jumper on the J2J1, Password PROT pins protects the system password during system reset. Moving the jumper to the CLR pins clears the system password during system reset.

To clear and enter your password, do this:



Your System.”

3. Move the jumper on the J2J1, Password PROT pins to the CLR pins.


5. Turn the system on, and wait for POST to complete. This automatically clears the password. For instructions on running POST, see Chapter 3,


6. Turn the system off; disconnect the power cord(s), and remove the left side cover.

7. Move the jumper on the J2J1, Password CLR pins to the PROT pins.


9. Run the SCU to specify a new password. For information on running the SCU, see Chapter 3, “Configuring The System.”


183

CMOS

The jumper on the J2J1, CMOS PROT pins preserves the CMOS settings during system reset. Moving the jumper to the CLR pins clears CMOS and sets it and the real-time clock (RTC) to the manufacturing default settings during system reset.

To reset the system’s CMOS and the RTC to factory default values, do this:



Your System.”

3. Move the jumper on the J2J1, CMOS PROT pins to the CLR pins.


5. Turn the system on, and wait for POST to complete. This automatically reprograms CMOS and RTC to their default settings. For instructions on running POST, see Chapter 3, “Configuring The System.”

6. Turn the system off, disconnect the power cord(s) from the system, and remove the left side cover.

7. Move the jumper on the J2J1, CMOS CLR pins to the PROT pins.

Solving Problems

10

This chapter helps you identify and solve problems that might occur while using the server.

Resetting the Server

You can reset the server in a variety of ways.

Manually

Press

<Ctrl+Alt+Del>

Reset button

Power off/on

To

Clear system memory and reload the operating system.

This is a "soft boot" reset.

Clear system memory, restart POST, and reload the operating system.

Turn the system power off and then on. This is a "cold boot" reset; it has the same effect as pushing the reset button except that power is halted to all peripherals.

Programmed

You can reset the server with software.


201

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."

❑

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?

If the problems persist, contact the software vendor's customer service representative.


203

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.

Turn off the system and all external peripheral devices. Disconnect all of them from the system, except the keyboard and video monitor.

2.

Make sure the system power cord is plugged into a properly grounded

AC outlet. Refer to Chapter 2, "Installing The System."

3.

Make sure your video display monitor and keyboard are correctly connected to the system. Turn on the video monitor. Set its brightness and contrast controls to at least two-thirds of their maximum ranges

(refer to the documentation supplied with your video display monitor).

4.

If the operating system normally loads from the hard disk drive, make sure there is no diskette in drive A. Otherwise, place a diskette containing the operating system files in drive A.

5.

Turn on the system. If the power LED does not light, refer to "Power

Light Does Not Light" on page 207.


205

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

Once the system boots up, the operating system prompt appears on the screen. The prompt varies according to the operating system. If the operating system prompt does not appear, refer to "Initial System Startup" on page 202.

Configuration Utility (SCU).

Record the model and serial numbers of the server system and the system board. They are on the back panel of the server and along the left side of the system board near the expansion slots.

Record the model and serial numbers of the system components, dates of component removal or replacement, and the vendor’s name. Be sure to record the same information for any components added to the system, such as hard disk drives, add-in boards, or printers.

The location of serial numbers on add-in boards, hard disk drives, and external equipment, such as video displays or printers, varies from one manufacturer to another.
