General checkout

The server diagnostic prog rams are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server: The system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives, and parallel port. You can also use them to test some external devices. See “Diagnostic programs and error messages” on page 13.

Also, if you cannot determine whether a problem is caused by the hardware or by the softw a re, you ca n run the diagnostic programs t o confirm tha t the hard ware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

A failed system might be par t of a shared DASD cluster (two or more systems sharing the same external storage device(s)) . Prior to running diagnostics, verify that th e failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

• The customer identifies the system as part of a cluster.

• One or more external storage units are attached to the system and at least one of the attached storage units is additionally attached to another system or unidentifiable source.

• One or more sy stems are locate d near the failing system.

If the failing system is suspected to be part of a shared DASD cluster, all diagnostic tests can be run except diagnostic tests which test the storage unit (DASD residing in the storage unit) or the storage adapter attached to the storage unit.

Notes:

1. For systems that are part of a shared DASD cluster, run one test at a time in looped mode. Do not run all tests in looped mode, as this could enable the DASD diagnostic tests.

2. If multiple error code s are displaye d, dia gno se the first error code disp layed.

3. If the computer hangs with a POST error, go to the “Symptom-to-FRU index” on page 111.

4. If the computer hangs and no error is displayed, go to “Undetermined problems” on page 124.

5. Power supply problems, see “Power checkout” on page 16 and “Symptom-toFRU index” on page 111.

6. Safety information, see “Safety information” on page 133.

7. Fo r in termitte nt pro b le ms , check the erro r l og; see “POS T error messag es ” on page 12.

1. IS THE SYSTEM PART OF A CLUSTER?

YES. Schedule maintenance with the customer. Shut down all systems related to the cluster. Run storage test.

NO. Go to step 2.

2. IF THE SYSTE M IS NOT PART OF A CLUSTER :

• Power-off the computer and all external devices .

• Check all cables and power cords.

• Set all display controls to the middle position.

• Power-on all external devices.

• Power-on the computer.

• Record any POST error messages displayed on the screen. If an error is displayed, look up the first error in the “POST error codes” on page 119.

• Check the diagnostic LED panel system error LED; if on, see “Front panel and system board LEDs” on page 18.

• Check the System Error Log. If an error was recorded by the system, see “Symptom- to- F RU index” on page 111.

• Start the Diagnostic Programs. See “Diagn ostic programs and error messages” on page 13.

• Check f or the following responses: a. One beep. b. Readable instructions or the Main Menu.

3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?

NO. Find the failure symptom in “Symptom-to-FRU index” on page 1 11.

YES. Run the D ia g n o st ic program s. If necessary, refer to “D iagnostic p rog r a ms and

error me ssages” on page 13.

If you receive an error, go to“Symptom-to-FRU index” on page 1 11 .

If the diagnostics completed successfully and you still suspect a problem, see “Undetermined problems” on page 124.

Starting the server

After you plug the power cord of your server into the power supply and an electrical outlet, the server can start in any of the following ways:

• You can press the power-control button on the front of the server to start the server.

Notes:

1. You can install a circular disk over the power-control button to prevent

accidental manual power-off. This disk, known as the power-control bu tton shield, comes with your server .

2. After you plug the power cord of your server into an electrical outlet, wait

approximately 20 seconds before pressing the power-control button. During this time, the system is initializing; therefore, the power-control button does not respond.

• If the server is turned on and a power failure occurs, the server will start automatically when power is restored.

• The Wake on LAN feature will turn on the server at the set time (when a Magic Packet is received), provided that all of the following conditions are met:

— AC power is present. — The server i s e ither off or shu t down from an Advanced Configuration and

Power Interface (ACPI) operating system.

POST

When you turn on the server, it performs a series of tests to check the operation of server components an d some of the options installed in th e se rver. This se ries of tests is called the power-on self-test or POST.

If POST finishes without detecting any problems, a single beep sounds and the first screen of the operating system or application program appears.

If POST detects a problem, more than one beep sounds and an error message appears on the screen. See “POST beep codes” and “POST error messages” for more information.

Notes:

1. If you have a power-on password set, you must type the password and press Enter, when prompted, before POST will continue.

2. A single problem might cause several error messages. When this occurs, work to correct the cause of the fir st e rror message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the te s t .

POST beep codes

POST generates beep codes to indicate successful completion or the detection of a problem.

• One beep indicates the successful completion of POST.

• More than one beep indicates that POST detected a problem. For more information, see “Beep symptoms” on page 111.

POST error messages

POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. For a list of POST errors, se e “ P O S T error codes” on page 119.

POST error log

The POST error log contains the three most recent error codes and messages that the syste m gener a te d du ring PO ST.

To view the contents of the error logs, start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utilit y program” on page 30); then, sele ct Error Logs from the main menu.

Small computer system interface messages

The following table lists actions to take if you receive a SCSI error message. Note: If your server does not have a hard disk drive, ignore any message that

indicates that the BIOS is not installed.

You will get these messages only when running the SCSISelect Utility.

12 Hardware Maintenance Manual: xSeries 220

SCSI Messages Description

All One or more of the following might be causing the problem.

• A failing SCSI device (adapter, drive, controller)

• An improper SCSI configuration

• Duplicate SCSI IDs in the same SCSI chain

• A n improperly installed SCSI terminator

• A defective SCSI terminator

• A n improperly installed cable

• A defectiv e cable

Action:

• The cables for all external SCSI devices are connected correctly.

• The last device in each SCSI chain is termin ated prope r l y.

• The SCSI devices are co nfigured co r rectly.

If the above items are correct, run the diagnostic programs to obtain additional information about the failing device. If the error remains or recurs, call for service.

Table 1. SCSI messages.

Diagnostic programs and error messages

The server diagnostic prog rams are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server.

Diagnostic error messages indicate that a problem exists ; they ar e not necess aril y intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Somet i m e s th e f i rs t e rro r to occur caus e s add i tional erro rs . In this case , the se r v er displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when running the diagnostic programs.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where: fff is the thre e -digit fun ction code that in di cates the function being

tested when the error occurred. For example, function c od e 089 is for the microprocessor.

ttt is the thre e -digit failure code that indicates the exact test failu re that

was encou ntered.

Diagnostics 13

iii is the thr e e-digit device ID. date is the date that the diagnostic test was run and the error recorded. cc is the check digit that is used to verify the validity of the information. text message is the diagnostic message that indicates the rea son for the problem .

Text messages

The diagnostic text message format is as follows:

Function Name: Result (test specific string)

where: Func tion Name is the name of the function being tested when the err or occurre d. This

corresponds to the function code (fff) given in the previous list.

Result can be one of the following:

Passed This result occurs when the diagnostic test com p letes

without any errors.

Failed This re sult occurs when the di agnostic te st discovers an error. User Aborted

This r e su lt occurs when y ou s top the diagnosti c test before it is complete.

Not Applicable

This result occurs when you specify a diagnostic test for a device that is not present.

Aborted This result occurs when the test could not proceed because

of the syste m configurati on.

Warning This result occurs when a possible problem is rep orted

during the diagnostic test, such as when a device that is to be tested is not installed.

and try running the diagnostic programs again.

b. The keyboard and mouse (pointing device) tests assume that a keyboard and

mouse are attached to the server.

c. If you run the diagnostic programs with no mouse a tta ched to the server, you

will not be able to navigate between test categories using the Next Cat and Prev Cat buttons. All other functions pro vided by mouse-sel e ctable buttons are also available using the function keys.

d. You can run the USB interface test and the USB external loopback test only if

there are no USB devices attached.

e. You can view server configuration information (such as system configuration,

memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on) by selecting Hardware Info from the top of the screen.

When the tests have completed, you can view the Test Log by selectin g Utility from the top of the screen.

If the hardware checks out OK but the problem persists during normal server operations, a software error might be the cause. If you suspect a software problem, refer to the information that comes with the software package.

Viewing the test log

The test log will not contain any information until after the diagnostic program has run.

Note: If you already are running the diagnostic programs, begin with step 3.. To view the test log:

1. Turn on the server and watch the screen. If the server is on, shut down the operating system and restart the server.

2. When the message F2 for Diagnostics appears, press F2. If a power-on password is set, the server prompts you for it. Type in the

Power checkout

Power problems can b e difficu lt to trou bleshoot. For instance, a short circui t can exist anywhere on any of the power distribution bu sses. Usually a short circuit will cause the power su b s ystem to shut d own because of an overcurrent conditi o n.

A general procedure for troubleshooting power problems is as follows:

1. Power off the system and disc onnect the AC cord(s).

2. Check for loose cables in the power subsystem. Also check for short circuits, for

3. Remove adapters and disconnec t th e cables and power connectors to all intern al

successfully, replace adapters and devices one at a time until the problem is isolated. If system does not power up from minimal configuration, replace FRUs of minimal configuration one at a time until the problem is isolated.

If the BIOS has become damaged, such a s from a power failure during a flash updat e, you can recover the BIOS using the flas h ROM page-swa p jumper (J38) and a BIOS flash diskette.

Note: You can obtain a BIOS flash diskette fr om one of the following sources:

• Use the ServerGuide program to make a BIOS flash diskette.

• Download a BI OS f lash diskette from the World Wide Web. Go to http://www.ibm.com/pc/support/, select IBM Server Support, and make the selections f o r your serve r.

The flash memory of your server consists of a primary page and a backup page. The J38 jumper controls which page is used to start the server. If the BIOS in the primary page is damaged, you can use the backup page to star t the server; then, start the BIOS flash diskette to restore the BIOS to the primary page.

To rec ove r th e BIOS, do the f oll ow ing :

1. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover.

2. Locate jumper J38 on the system board .

Working with ad ap ters

Y ou can install up to five peripheral component interconnect (PCI) adapters in the PCI slots on the syste m boar d of the server. See the xSeries 220 ServerProven list at http://www.ibm.com/pc/compat/ for a lis t of PCI adapter s th at the server supports.

The server comes with an inte grat ed vid eo cont roller, which is a component on the system board. When you inst all a video adapter, the server BIOS automatically disables the integrated video controller.

Note: The illustrations in this document might differ slightly from your hardware.

Installing options 63

The following illustration shows the location of the 33 MHz PCI slots on the system board.

PCI slot 1 32-bit 33 MHz (J29)

PCI slot 4 64-bit 33 MHz (J39)

PCI slot 5 64-bit 33 MHz (J40)

Adapter considerations

Before you install adapters, review the following:

• Locate the documentation that comes with the adapte r and fol l ow those instructions in addition to the instructions given in thi s chapter. If you need to change switch or jumper settings on your adapter, follow the instructions that come with th e adapter.

• You can install full-length adapters in all PCI slots.

• You can instal l a 32-bit adapter in any of the PCI slots, but you might want to install it in a 32-bit sl ot and use the 64-bit slots for 64-bit adap ters.

• The server supports 5.0V and universal PCI adapters; it does not support 3.3V adapters.

• The server uses a rotational interrupt technique to configure PCI adapters. Because of this techni que, you can install a variety of PCI adapters that currently do not support sharing of PCI interrupts.

• The server has two PCI buses. P CI slots 1 and 2 are on PCI bus A and PCI slots 3, 4, and 5 are on PCI bus B.

Note: PCI bus A is sometimes referred to as bus 0; PCI b u s B i s sometimes

referred to as bus 1.

The system scans PCI slots 1 through 5 to assign syste m resources; then the system starts (boots) the PCI devices in the following order: PCI slots 1 and 2, system board SCSI devices, and then PCI sl ots 3 through 5.

• If you plan to use the Wake on LAN (WOL) function in the server, you must install a Wake on LAN-enabled NIC adapter in PCI slot 1, and install the Wake on LAN cable that comes with the Wake on LAN adapter to connect this adapter to the system board. You must use a W ake on LAN-enabled adapter as identified in the xSeries 220 ServerProven list at http://www.ibm.com/pc/com pat/. Only PCI slot 1 supports a Wake on LAN-enabled adapter. For addition al information on the Wake on LAN function, adapters, and cables, refer to the doc umentation that comes with the Wake on LAN adapters.

• If you plan to use the optional system management adapter in the server, you must install the opti onal system manag e me nt adapter in PCI slot 2. Only PCI slot

64 Hardware Maintenance Manual: xSeries 220

2 supports the optional system management adapter. For additional information on the optional system manageme nt adapter, refer to the docume ntation that comes with the adapter.

Attention: When you handle electrostatic discharge (ESD) sensitive devices, take precautions to avoid damage from static electricity. For details on handling these devices, see “Handling electrostatic discharge-sensitive devices” on page 136.

To ins tall an adapte r, do the following:

1. Review the safety precautions in “Safety information” on page 133.

2. Turn off the server and peripheral devices, and disconnec t al l external cables and power cords; then, remove the side cover. See “Removing the side cover” on page 59 for details.

3. Carefully remove the support bracket assembly from the server (see “Removing the support bracket assembly” on page 61). Store the cover and the support bracket assembly in a safe place.

4. Determine which PCI slot you will use for the adapter. Note: Check the instructio ns that come with the adapter for any requirements or

restrictions.

5. Remove the rear adapter retaining bracket from the server. If you are installing a full-length adapter, rotate the front adapter support b racket to the open (unlocked) position.

6. Remove the expansion-slot cover. Store it in a safe place for future use.

Installing options 65

Attention: Expansion-slot covers must be installed on all vacant slots. This maintains the electronic emission charac terist ics of the system and ens ures pr oper cooling of system components.

7. Refer to the documentation that comes with your adapter for any cabl ing instructions. It might be easier for you to route cables before you install the adapter.

8. Remove the adapter from the static-prot ective package. Attention: Av oid touching the components and gold-edge connectors on the

adapter.

9. Place the adapter, component-side up, on a flat, static-protective surface.

10. Set any jumpers or switches as described by the adapter manufacturer.

11. Instal l the adap t e r: a. Carefully grasp the adapter by its top edge or upper corners, and align it with

the expansion slot on the system board.

b. Press the adapter firmly into the expansion slot.

Attention: When you install an adapter in the server, be sure that it is completely and correctly seated in the system-board connector before you apply power. Incomplete insertion might cause damage to the system board or the adapter.

c. When the adapter is fully seated, release the fr ont adapter support bracket by

pushing inward on the latch. Make sure that the front adapter support bracket holds the adapter secu rely in place.

d. If you open e d th e f ront adapter su p p ort bracket, rotate it to the cl ose d

(locked) position; then, reinstall the rear adapter retaining bracket in the server.

12. Connect any needed cables to the adapter.

Attention: Route cables so that they do not block the flow of air from the fans.

Note: If the server is a hot-sw ap mod el, reinstall the VRM in connector J42 after

you reinstall the su pport bracket assembly. (See “System board options connectors” on page 55 for connector location .)

Installing a hot-swap hard disk drive in bay 5, 6, or 7

If the server is a hot-swap model, it contains hardware that you can use to replace a failed hard disk drive without turning off the server. Therefore, you have the advantage of continuing to operate the system while a hard disk drive is removed or installed. These drives are known as hot-swap drives . If these drives are connected to an optional contr o ller, such as a ServeRAI D cont roll er, that supports th is fun ction , and if one of these drives becomes defective, the ServeRAID controller can rebuild the data fr om that driv e onto an other hot-s wap dr ive. Refer to the info rma tion th at c omes with th e Se rv e R A ID co n t rol le r fo r de t ails.

Each hot-swap drive has two in di cator lights: the hard dis k drive activity light and the hard disk drive status light. When the green hard disk drive activity light is flashing, the controller is accessing the hard disk drive. When this occurs, the SCSI activity light on the front of the server also illuminates. The SCSI activity light is illustrated and described in “Server controls and indicators” on page 6. If the amber hard disk drive status light for a drive is lit continuously, that individual drive is faulty and requires replacement. When the hard disk drive status light indicates a drive fault, you can replace a hot-swap drive without turning off the server .

Note: The hard disk drive activity light is also known as the SCSI hard disk drive

activity light.

Each hot-swap driv e that you plan to ins tall must be mount ed in a hot-s w ap-d rive tray. The drive must have a single connector attach ment (SCA) co nn ector. Hot-swapdrive trays come with hot-swap drives.

The hot-swap ba ys connect to a SCSI backplane. This backplane is the printed circuit board behind the bay. The backplane controls the SCSI IDs for the hot-swap drives.

The following illustration shows the hot-swap-drive backplane component locations, as viewed from the front of the server.

Note: The illustrations in this document might differ slightly from your hardware.

Filler panel

Drive tray assembly

Drive tray handle (in open position)

Attention:

• When you handle electrostatic discharge (E SD) sensitiv e devices, take pr ecaut ions to avoid damage from static electricity . For details on handling these devices, see “Handling electrostatic d ischarge-sensitive devices” on page 136.

• To maintain proper system cooling, do not operate the server for more than 10 minutes without either a driv e or a filler panel installe d in each bay.

To install a hot- swap hard disk drive in bay 5, 6, or 7, do the following:

1. Review “Before you begin” on page 58.

2. Read the information in “Prein stallation steps (all bays)” on page 69. Note: You do not h a ve to tu rn off the server to install ho t- s w ap hard dis k d rives

in these bays.

3. Remove the filler panel from one of the empty hot-swap ba ys by insertin g your finger into the depression at the left side of the filler panel and pulling it away from the server.

4. Install the hard disk drive in the hot-swap bay: a. Ensure that the tray handle is open (that is, perpendicular to the drive). b. Align the drive tray assembly with the guide rails in the bay. c. Gently push the dr ive tray assemb ly into the ba y until the drive stops . d. Push the tray handle to the closed (locked) position. e. Check the hard disk drive status light to verify that the hard disk drive is

operating properly. If the amber hard disk drive status light for a drive is lit continuously, that

individual drive is faulty and needs to be replaced. If the green hard disk drive activity light is fl ashing, the drive is being accessed.

Note: If the server has a ServeRAID contr oller, you might need to reconfigure the

disk arrays after installing hard disk drives. Refer to the informa tion that comes with the ServeRA ID controller.

Installing memory modules

Adding memory to the server is an easy way to make programs run faster. You can increase the amount of memory in the server by installing options called memory- module kits. Each kit contains one i ndustry-standard, dual in-line memory module (DIMM). The server uses a noninterleaved memory configuration.

The server comes with a dual in-line memory module (DIMM) that is installed on the system board in DIMM slot 1 (connec tor J19).

Notes:

1. When insta lling add itio nal mem o ry module s, ins tall the seco nd mem o ry module in the connector labeled DIMM3 (J23), the third in DIMM2 (J21), and the fourth in DIMM4 (J26). (See the following illustration for memory-connector locations.)

2. The xSeries 220 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. These DIMMs ca n be installed in any memory slot. The se rver supports a minimum of 128 MB and a maximum of 4GB of system memory. See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory modules for use with the server.

3. Installing or removing DIMM s chang e s the configura tion info rmati on in the server. Therefore, after installing or removing a DIMM, you must save the new configuration information by using the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility progra m a n d se lect Save Se tt ing s . See “Configuring the server” on page 29 for more information.

and then on the other edge of the DIMM. Ensure that you press straight into the connector.

d. Make sure that the retaining clips are in the closed position. If a gap exists

between the DIMM and the retaining clips, the DIMM has not been properly installed. In this case, open the retaining clips and remove the DIMM; then, reinsert t he DIM M .

7. If you have othe r options to install or remove, do so now; other wi se, go to “Installing the cover” on page 83.

Attention: When you rest art the server, the system displays a message indicating that the memo ry configu ration ha s changed.

• If you installed additional m emor y, start the Configur ation /S etup Ut ility progra m a n d se lect Save Se tt ing s .

• If you just replaced a failed DIMM, you must start the Configuration /Setup Utility program, select Advanced Setup, select Memory Settings, highlight the connector or bank of connectors that you want to enable, then select Enable.

• In some memory configurations, the 3-3-3 beep code might sound during POST follow e d by a b la n k sc ree n. If this oc cu r s , y ou m u st res ta rt th e se r ve r three times to force the system BIOS to reset the memory connector or bank of connectors from Disabled to Enabled.

Installing and removing a microprocessor

The serve r comes with one microprocessor, which is installed on the system board. If you install an additi on al microprocessor kit, the server can operate as a symmetric multiprocessing (SMP ) serve r. With SMP, certain operating systems and a pp licatio n programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, int egrated manufacturing solu tions , and other applic atio ns .

Notes:

1. Before you install a new microprocessor, review the documentation that comes with th e mi cro p roc e ssor, so that you ca n de t e rm i n e whether yo u ne e d to update the server basic input/output system (BIOS). The latest level of BIOS for the server is available through the World Wide Web.

Installing options 77

2. Obtain an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.ibm.com/pc/compat/ on the World Wide Web.

3. The serve r comes with one microprocessor, which is installed in microprocessor connector U12 (the mi croprocessor connector that i s closer to the powe r supply). This is the startup (boot) microprocessor. If you install a micropro ce ssor in microprocessor connector U11, that one becomes th e startup microprocessor, and the microprocessor that is ins talled in microprocessor connector U12 is the application microprocessor. Y ou must also install a VRM when you install a microprocessor.

4. If you are installing a microprocessor that has a speed of 933 MHz or higher, you must also install a fan sink and connect the fan-sink power cable to the system board.

5. The illustrations in this document might differ slightly from your server.

6. If necessary, see “System board options connector s” on page 55 for connector locations.

Attention:

• To avoid damag e and ensure proper server ope ration when you install a new or addition al mi cro pr oc esso r, use micropr oc ess ors th at hav e th e same ca ch e size and type and the same clock speed. Microprocessor internal clock frequencies and external clock frequencies must be identical.

Universal Serial Bus ports

The server has two Universal Serial Bus (USB) ports, which configure automatically. USB is a serial interface standard for telephony and multimedia devices. It uses Plug and Play technology to determine the type of devi ce that is attache d to the connector.

Notes:

1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB ports and devices will be disabled during the power-on self-test (POST).

2. If you install a USB keyboard that has a mouse port, the USB keyboard emulates a mouse, and you will not be able to disable the m ouse set tings in the Configuration/ Se tup Ut ility program .

USB cables and hubs

You need a 4-pin cable to connect devices to USB 1 or USB 2. If you plan to att ach more than two USB devices , y ou must use a hub to connec t the devices. Th e hub provides multiple connectors for attaching additional external USB devices.

USB technology provides up to 12 megabits-per-second (Mbps) speed with a maximum of 127 external devic e s and a maximum sign al distance of five meters (16 ft) per segment.

USB-port connectors

Each USB port has an external connector on the system board for attaching USBcompatible dev ices .

Video port

The server comes with an integrated super vid e o gr ap hics array (SVGA) video controller. This controller is not removable, but you can disable it by installing a PCI video adapter.

Note: If you install a PCI video adapter, the server BIOS will automatically disable

the integrated video controller.

SCSI port

The server has an integrated small computer system interface (SCSI) controller with an internal connector (J41) on the system board. This control ler supports an Ultra160 SCSI internal channel. This channel supports up to 15 SCSI devices. In addition, this controller uses:

• Double-transition cl ocking to achieve h igh transfer rates

• Domain name validation to negotiate compatible data transfer speeds with each device

• Cyclic-redundancy checking (CRC), instead of the usual parity checking, to significantly improve data reliability

• An active terminator on the system board for SCSI bus termination

If you install a SCSI adapter in the server, you can use its SCSI connector to connect different types of small computer system interface (SCSI) devices.

Note: If you install a PCI r ed u ndant array of independent disks (RAID) adapter, you

can move the SCSI cable from the system-board SCSI connector to an internal channel connector on the RAID adapter if you want to control the internal drives from the adapter.

SCSI cabling requirements

A SCSI cable comes with the server so that you can connect internal SCSI devices to the SCSI controller on the system board. A 2-drop SCSI cable comes with the models that have th e hot- swa p drive ca ge option . A 5-dr op SCSI ca b le come s with the model s that have the standard non-hot-swap drive cage. If you plan to use the SCSI cable to connect internal SCSI devices to another SCSI or ServeRAID controller (for example, an optional PCI adapter ), you must purchase and install an opti on al SCSI cable to connect other SCSI devices (for example, a tape drive) to the SCSI connector on the system board. I f you plan to attach ext ernal SCS I devices, you must inst all an opt ional SCSI adapter and order additional SCSI cables.

For information about the maximum length of SCSI cable between the terminated ends of the cable, refer to the ANSI SCSI standards. Adhering to these standards will help ensure that the server operates properly.

Setting SCSI IDs

Each SCSI device that is connected to a SCSI contr oll er or adapter must have a unique SCSI ID. This ID enables the SC SI con troller o r adap ter to ident ify the dev ice an d ensur e that different devices on the same SC SI channel do not attempt to transfer data simultaneously. SCSI devices that are connected to differ ent SCSI channel s can have duplicate SCSI IDs.

To install external SCSI devices, you must firs t install an optional SCSI PCI adapter. Refer to the information that is provided with the device for instructions to set its SCSI ID.
