General checkout

The server diagnostic programs 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 tools overview” on page 11.

Also, if you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware 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 part of a shared DASD cluster (two or more systems sharing the same external storage device(s). Prior to running diagnostics, verify that the failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

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

v One or more systems are located 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 codes are displayed, diagnose the first error code displayed.

3. If the computer hangs with a POST error, go to “System Error logs” on page 14.

4. If the computer hangs and no error is displayed, “Diagnostic programs and

error messages” on page 14.

5. Power supply problems, “Power supply LED errors” on page 112.

6. For intermittent problems, check the error log; “Undetermined Problems” on

page 122.

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. THE SYSTEM IS NOT PART OF A CLUSTER

v Power-off the computer and all external devices.

v Check all cables and power cords. v Set all display controls to the middle position. v Power-on all external devices. v Power-on the computer. v Record any POST error messages displayed on the screen. If an error is

displayed, look up the first error in the “System Error logs” on page 14.

v Check the information LED panel System Error LED; if on, see “Operator

information panel” on page 10.

v Check the System Error Log. If an error was recorded by the system, see

“System Error logs” on page 14.

v Start the Diagnostic Programs. See “Starting the diagnostic programs” on

page 16.

v Check for the following responses:

a. One beep. b. Readable instructions or the Main Menu.

3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?

YES. Run the Diagnostic Programs. If necessary, refer to “Starting the diagnostic programs” on page 16.

NO. Find the failure symptom in “Symptom-to-FRU index” on page 103.

Diagnostics

This section provides basic troubleshooting information to help you resolve some common problems that might occur with your server.

If you cannot locate and correct the problem using the information in this section, refer to “Diagnostic tools overview” for more information.

Diagnostic tools overview

The following tools are available to help you identify and resolve hardware-related problems:

v POST beep codes, error messages, and error logs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. See “POST beep code descriptions” on page 13 for more information.

v Light Path Diagnostics

Your server has light-emitting diodes (LEDs) to help you identify problems with server components. These LEDs are part of the Light Path Diagnostics feature that is built into your server. By following the path of lights, you can quickly identify the type of system error.

v Diagnostic programs and error messages

The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of your server. See “Diagnostic programs and error messages” on page 14 for more information.

v Customized support page

You can create a customized support page that is specific to your hardware, complete with Frequently Asked Questions, Parts Information, Technical Hints and Tips, and Downloadable files.

IBM HelpCenter

When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test, or POST.

If POST finishes without detecting any problems, a single beep sounds, the first screen of your operating system or application program appears, and the System POST Complete (OK) light is illuminated on the operator information panel.

If POST detects a problem, more than one beep sounds and an error message appears on your screen. See “POST beep code descriptions” on page 13 and “System Error logs” on page 14 for more information.

Notes:

1. If you have a power-on password or administrator 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 first error 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 test.

12 Hardware Maintenance Manual: Type 8668

Page 21

POST beep code descriptions

Beep codes are sounded in a series of long and short beeps.

The possible types of beep codes that your server might emit include the following:

No beeps

If no beep occurs after your server completes POST (that is, after the system POST complete (OK) light on the operator information panel is illuminated), call for service.

Continuous beep

Your startup (boot) microprocessor has failed, or your system board or speaker subsystem might contain a failing component. If the system continues through POST with no errors, call for service. If no video appears, the startup processor has failed; replace the startup processor.

One short beep

One beep indicates that your server successfully completed POST. POST detected no configuration or functional errors. One beep also occurs after your server completes POST if you type an incorrect power-on password.

Two short beeps

POST encountered an error. The Configuration/Setup Utility program will display additional information; follow the instructions that appear on the screen. See “System Error logs” on page 14 for descriptions of the text messages that might appear.

Three short beeps

A system memory error has occurred. This combination occurs only if the video basic input/output system (BIOS) cannot display the error message. Replace the failing memory module.

Repeating short beeps

The system board might contain a failing component, your keyboard might be defective, or a key on the keyboard might be stuck. Ensure that:

v Nothing is resting on the keyboard and pressing a key. v No key is stuck. v The keyboard cable is connected correctly to the keyboard and to the

correct connector on the server.

Running the diagnostic tests can isolate the server component that failed, but you must have your system serviced. If the error message remains, call for service.

Note: If you just connected a new mouse or other pointing device, turn off

the server and disconnect that device. Wait at least 5 seconds; then, turn on the server. If the error message goes away, replace the device.

One long and one short beep

POST encountered an error on a video adapter. If you are using the integrated video controller, call for service. If you are using an optional video adapter, replace the failing video adapter.

One long and two short beeps

A video I/O adapter ROM is not readable, or the video subsystem is defective. If you hear this beep combination twice, both the system board and an optional video adapter have failed the test. This beep combination might also indicate that the system board contains a failing component.

Diagnostics 13

Page 22

One long and three short beeps

The system-board video subsystem has not detected a monitor connection to the server. Ensure that the monitor is connected to the server. If the problem persists, replace the monitor.

Two long and two short beeps

POST does not support the optional video adapter. This beep combination occurs when you install a video adapter that is incompatible with your server. Replace the optional video adapter with one that the server supports, or use the integrated video controller.

System Error logs

To view the contents of the error logs, start the Configuration/Setup Utility program; then, select Error Logs from the main menu.

The POST error log contains the three most recent error codes and messages that the system generated during POST. The System Event/Error Log contains all error messages issued during POST and all system status messages from the IBM remote supervisor adapter, if installed.

Small computer system interface messages (some models)

If you receive a SCSI error message while using the SCSISelect Utility. Use the following list to determine the possible cause of the error and what action to take.

Note: If your system does not have a hard disk drive, ignore any message that

indicates that the BIOS code is not installed.

v A failing SCSI device (adapter or drive) v An improper SCSI configuration v Duplicate SCSI IDs in the same SCSI chain v An improperly installed SCSI terminator v A defective SCSI terminator v An improperly installed cable v A defective cable

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

Action:

Verify that: v The external SCSI devices are turned on. External SCSI devices must be turned

on before the server.

v The cables for all external SCSI devices are connected correctly. v The last device in each SCSI chain is terminated properly. v The SCSI devices are configured correctly.

If the above items are correct, run the diagnostic programs to obtain additional information about the failing device.

Diagnostic programs and error messages

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

14 Hardware Maintenance Manual: Type 8668

Page 23

Diagnostic programs and error messages

Diagnostic error messages indicate that a problem exists; they are not 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.

Sometimes the first error to occur causes additional errors. In this case, the server 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:

Recovering BIOS

Recovering BIOS code

If the BIOS code has become damaged, such as from a power failure during a flash update, you can recover the BIOS using the recovery boot block and a BIOS flash diskette.

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

v Use the ServerGuide program to make a BIOS flash diskette. v Download a BIOS flash diskette from the World Wide Web. Go to

http://www.ibm.com/pc/support, select IBM Server Support, and make the selections for your server.

v Contact your IBM service representative.

The flash memory of your server contains a protected area that cannot be overwritten. The recovery boot block is a section of code in this protected area that enables the server to start up and to read a flash diskette. The flash utility recovers the system BIOS code from the BIOS recovery files on the diskette.

To recover the BIOS:

Note: Default to pins 1 and 2 and is highlighted.

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

2. Locate the boot block jumper block (J16) on the system board.

3. Move jumper to pins 2 and 3 to enable BIOS back-up page.

4. Insert the BIOS flash diskette into the diskette drive.

5. Restart the server.

6. The system begins the power-on self-test (POST). Select 1 - Update

POST/BIOS from the menu that contains various flash (update) options.

Hardware Maintenance Manual: Type 8668

7. When you are asked if you would like to move the current POST/BIOS image

to the backup ROM location, type N. Attention: Typing Y will copy the corrupted BIOS into the secondary page.

8. When you are asked if you would like to save the current code to a diskette,

select N.

9. You will be asked to choose which language you wish to use. Select your

language (0-7) and press Enter to accept your choice. You will be prompted to remove the diskette and press Enter to restart the system. Remove the flash diskette from the diskette drive.

Attention: Do not press Enter to reboot the system at this time.

10. power-off the server.

11. Move jumper J16 back to pins 1 and 2 to return to normal startup mode.

12. Restart the server. The system should start up normally.

Identifying problems using status LEDs

If the System Error light in the operator information panel on the front of the server is on, one or more LEDs inside the server may be on. Use the Light Path Diagnostics feature to identify the type of error that occurred. See “Diagnostic tools overview” on page 11.

Recovering BIOS

You can use the Light Path Diagnostics feature built into your server to quickly identify the type of system error that occurred. Your server is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the ac power source is good and the power supplies can supply +5 V dc current to the server. This feature helps you isolate the problem if an error causes the server to shut down. See “Diagnostic tools overview” on page 11.

Power-Supply LEDs

The ac and dc power LEDs on the power supply provide status information about the power supply.

Switch description

When On, the host bus speed is 100 MHz. When Off, the host bus speed is 133 MHz. The switch should always be set to Off to optimize the system performance. Setting switch 5 to On greatly reduces system performance.

When toggled to the opposite position, POST will ignore the power-on password setting, if one is set.

When On, overrides the power-on switch and forces power-on mode. The system will always start without the use of the power-on switch. Note: When power-on switch is set to the On position you can not power down from the front panel.

System reliability considerations

To help ensure proper cooling and system reliability, make sure:

v Each of the drive bays has either a drive or a filler panel installed. v Each of the power supply bays has either a power supply or a filler panel

installed.

v The cover is in place during typical operations, or is removed for no longer than

30 minutes while the server is operating.

Note: The front door (tower model) can be removed permanently without

affecting system reliability.

Installing options 41

Page 50

v There is space around the server to enable the server cooling system to work

properly. – On a tower model, leave approximately 127 mm (5 inches) of space around

the front and rear of the server.

– On a rack model, refer to the documentation that comes with the rack.

v A removed hot-swap drive is replaced within two minutes of removal. v Cables for optional adapters are routed according to the instructions provided

with the adapters.

v A failed fan must be replaced immediately.

Working inside a server with power on

Your server is designed to operate safely while turned on with the cover removed, such as when you set the password-override switch. Follow these guidelines when you work inside a server that is turned on:

v Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before

working inside the server; do not wear cuff links while you are working inside the server.

v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist

watches.

v Remove items from your shirt pocket (such as pens or pencils) that could fall

into the server as you lean over it.

v Take care to avoid dropping any metallic objects, such as paper clips, hair pins,

or screws, into the server.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its anti-static package, touch it to an unpainted metal

part of the system unit for at least two seconds. (This drains static electricity from the package and from your body.)

v Remove the device from its package and install it directly into your system unit

without setting it down. If it is necessary to set the device down, place it in its static-protective package. (If your device is an adapter, place it component side up.) Do not place the device on your system unit cover or on a metal table.

v Take additional care when handling devices during cold weather; heating

reduces indoor humidity and increases static electricity.

Adapter considerations

Before you install adapters, review the following: v Locate the documentation that comes with the adapter and follow those

instructions in addition to the instructions given in this chapter. If you need to change the switch or jumper settings on your adapter, follow the instructions that come with the adapter.

v You can install full-length adapters in all expansion slots. v You can install a 32-bit adapter or device in any of the PCI slots. v Your server supports 5.0 V and universal PCI adapters in PCI slots 1, 2, and 3; it

supports 3.3 V and universal adapters in PCI slots 4 and 5.

Note: Some full-length adapters with attached daughterboards might interfere

with SCSI channel B if installed in slot 1. Install these cards in slots 2, 3, 4, or 5.

v You might require additional power supplies if adapters are added that have

electrical current requirements that exceed the installed power-supply capabilities.

v Your server uses a rotational interrupt technique to configure PCI adapters.

Therefore, you can install a variety of PCI adapters that currently do not support sharing of PCI interrupts.

v The optional IBM Remote Supervisor Adapter must be installed in PCI slot 1

only. The ribbon cable that ships with the adapter is required to connect the adapter to the system board. The external power adapter that ships with the adapter is not required with this server.

v PCI slot 1 is on PCI bus A, PCI slots 2 and 3 are on PCI bus B, and PCI slots 4

and 5 are on PCI bus C.

Note: PCI bus A is often referred to as bus 0; PCI bus B is often referred to as

bus 1; and PCI bus C is often referred to as bus 2.

or restrictions.

4. Remove the expansion-slot cover: a. Press the arrow on the adapter retention bracket release tab and remove

the bracket.

b. Slide the expansion-slot cover out of the server. Store it in a safe place for

future use.

Attention: Expansion-slot covers must be installed in all vacant slots. This maintains the electronic emissions characteristics of the system and ensures proper cooling of system components.

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

6. Remove the adapter from the static-protective package.

Hardware Maintenance Manual: Type 8668

Page 59

Removing the server door (tower model)

Attention: Avoid touching the components and gold-edge connectors on the adapter.

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

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

9. Install the adapter: a. If necessary, remove the adapter support bracket retaining clip. b. Carefully grasp the adapter by its top edge or upper corners, and align it

with the expansion slot on the system board.

c. 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.

d. Replace the retaining clip on the adapter support bracket, if you removed

it.

e. Align the bottom tabs of the adapter retention bracket with the holes at the

top of the expansion slots, and press the adapter retention bracket toward the back of the server until it clicks into the locked position.

Installing internal drives

Different types of drives enable your system to read multiple types of media and store more data. Several types of drives are available, such as:

v Diskette (already installed) v Hard disk v CD-ROM (already installed) v Tape, including DLT

Internal drive bays

Internal drives are installed in bays. The bays of the xSeries 232 are in the front of the server, as shown in the following illustrations.

Hot-swap drives

Your server contains hardware that enables you to continue to operate your system while a hard disk drive is removed or installed. These drives are known as hot-swap drives.

Each hot-swap drive that you plan to install must have a hot-swap-drive tray attached. Hot-swap-drive trays come with the hot-swap drives.

v Your server supports six slim (1-inch) line, SCSI LVD, 3.5-inch hot-swap hard

disk drives in the hot-swap bays.

v The hot-swap bays connect to a SCSI backplane. This backplane is the printed

circuit board behind the bay.

v The backplane controls the SCSI IDs for the hot swap drives.

Non-hot-swap drives

Diskette drives, tape drives, and CD-ROM drives are non-hot-swap drives. To remove or install a non-hot swap drive, you must turn off the server first. Non-hot-swap drives are installed in bays A, B, C, and D only.

v Your server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive in bay D

and a preinstalled IDE CD-ROM drive in bay C.

v The xSeries 232 server supports only one diskette drive. v The diskette drive uses 1 MB and 2 MB diskettes. For optimum use, format

1 MB diskettes to 720 KB, and format 2 MB diskettes to 1.44 MB.

v Bays A and B come without a device installed. These bays are for 5.25-inch,

half-high, removable-media drives, such as tape backup drives. You can combine bays A and B into a single full-high bay.

v If you are installing a SCSI device with a 50-pin connector in one of the empty

non-hot-swap bays (bays A–B), you need a 68-pin to 50-pin converter. To order the converter, contact your IBM reseller or IBM marketing representative.

Note: The server electromagnetic interference (EMI) integrity and cooling are both

protected by having bays A and B covered or occupied. When you install a drive, save the filler panel from the bay, in case you later remove the drive and do not replace it with another.

Preinstallation steps (all bays)

Before you install drives in your server, verify that you have all the cables and any other equipment specified in the documentation that comes with the internal drive. You might also need to perform certain preinstallation activities. Some of the steps are required only during the initial installation of an option.

1. Read “Important safety information” on page v, “Handling static-sensitive devices” on page 42, and the documentation that comes with your drive.

2. Choose the bay in which you want to install the drive.

3. Check the instructions that come with the drive to see if you need to set any

switches or jumpers on the drive.

4. To install the drive, go to “Installing a hot-swap drive” on page 55 or to “Installing a non-hot-swap drive” on page 57, as appropriate.

To install a drive in a hot-swap drive bay:

Attention:

v To maintain proper system cooling, do not operate the server for more than two

minutes without either a drive or a filler panel installed for each bay.

v When you handle static-sensitive devices, take precautions to avoid damage

from static electricity. For details on handling these devices, review “Handling static-sensitive devices” on page 42.

1. Remove the filler panel from one of the empty hot-swap bays by inserting your finger into the depression at the left side of the filler panel and pulling it away from the server.

2. Install the hard disk drive in the hot-swap bay: a. Ensure the tray handle is open (that is, perpendicular to the drive). b. Align the rails on the drive assembly with the guide rails in the drive bay. c. Gently push the drive assembly into the bay until the drive connects to the

backplane.

d. Push the tray handle toward the closed position until it locks the drive in

place.

3. Check the hard disk drive status indicators to verify that the hard disk drives are operating properly (see “Server controls and indicators” on page 6 for the location of the status indicators).

v If the amber light is on continuously, the drive has failed. v If you have a RAID adapter installed:

– When the amber light flashes slowly (one flash per second), the drive is

being rebuilt.

– When the amber light flashes rapidly (three flashes per second), the

controller is identifying the drive.

Note: If your server has a RAID adapter installed, refer to the information

provided with the RAID adapter for information about adding a drive.

Replacing a drive in a hot-swap bay

You do not have to turn off the server to remove or install the hot-swap drives.

Attention:

1. Before you remove a hot-swap hard disk drive that is not defective, back up all important data.

2. To avoid damage to a hard disk drive, do not remove the drive from the hot-swap bay until it has had time to spin down (approximately 30 seconds). Handle the drive carefully.

3. Before you replace a hot-swap drive, make sure it is defective. If you partially or completely remove a good drive instead of a defective one, your server might lose data.

This situation is especially relevant if your server has a RAID adapter installed and you assigned RAID level 1 or 5 to the logical drives in your disk array. The RAID adapter can rebuild the data that you need, provided that certain conditions are met. Refer to the information provided with the RAID adapter for further details.

Refer to the following illustration of the tower model while you perform the steps in this procedure.

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

with the RAID adapter for information about replacing a drive.

2. If your server is a tower model, unlock and open the server door. Attention: To maintain proper system cooling, do not operate the server for

more than two minutes without either a drive or a filler panel installed for each bay.

3. Locate the defective drive (look for an amber Hard Disk Status light on the front of the drive).

4. Remove the defective hard disk drive. Move the handle on the drive to the open position (perpendicular to the drive), and pull the hot-swap drive assembly from the bay.

5. Install the hard disk drive in the hot-swap bay: a. Ensure the tray handle is open (that is, perpendicular to the drive).

Installing memory modules

Adding memory to your server is an easy way to make programs run faster. You can increase the amount of memory in your server by installing options called memory-module kits. Each kit contains one industry-standard, dual inline memory module (DIMM). Your server supports a two-way interleaved memory configuration. You must install matched pairs of memory kits. The set in slots 1 and 4 do not need to be the same size as the set in slots 2 and 3.

Notes:

1. Your server comes with two dual inline memory modules (DIMM) installed in DIMM connectors 1 and 4. Install additional DIMMs as instructed in the documentation that comes with your option.

2. Your xSeries 232 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. You must install the DIMMs in pairs of the same size. Place pair 1 in slots 1 and 4 and pair 2 in slots 2 and 3. Refer to the ServerProven Wide Web at http://www.ibm.com/pc/compat for information about memory modules for use with your server.

3. Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing a DIMM, you must save the new configuration information in 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 program and select Save Settings.

and then on the other edge of the DIMM. Be sure to press straight into the connector. Be sure that the retaining clips snap into the closed position.

c. Make sure 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 the DIMM.

d. Repeat steps 4a through 4c for the second DIMM; then continue with step 5.

5. If you have other options to install or remove, do so now; otherwise, go to the

“Installing the bezel and front door” on page 80.

Installing a microprocessor

Your server comes with one microprocessor installed on the system board. If you install an additional microprocessor, your server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Notes:

1. Before you install a new microprocessor, review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server basic input/output system (BIOS) code. The latest level of BIOS code for your server is available through the World Wide Web. Refer to “Online Support” on page vi for the appropriate World Wide Web addresses.

Hardware Maintenance Manual: Type 8668

Page 71

Installing a microprocessor

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

Your server comes with one microprocessor installed in the microprocessor connector (U68) that is closest to the power supply. This is the startup (boot) microprocessor. A microprocessor installed in connector U69 is microprocessor

2. If more than one microprocessor is installed, the microprocessor installed in microprocessor connector U69 is the startup processor, and the microprocessor installed in U68 is the application processor.

Attention: To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. See the ServerProven list at http://www.ibm.com/pc/compat for a list of microprocessors for use with your server.

Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

Adding a hot-swap power supply

When the hot-swap power supply backplane is installed you can replace the 385-watt power-supply with an optional backplane. This backplane supports up to three power supplies, which enables redundancy and will make the power supplies hot-swappable. After you install a power supply, verify that the power-supply status indicators (ac power light and dc power light) are lit, indicating that the power supply is operating properly.

Notes:

1. You do not need to turn off the power to the server to install hot-swap power

supplies.

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

finger into the depression on the filler panel and pulling it away from the server. Save the filler panel in case you remove the power supply at a later time.

Note: During typical operation, each power-supply bay must have either a

power supply or filler panel installed for proper cooling.

2. Install the power supply in the bay: a. Place the handle on the power supply in the open position (that is,

perpendicular to the power supply) and slide the power supply into the chassis.

b. Gently close the handle to seat the power supply in the bay.

3. Plug the power cord for the added power supply into the power cord

connector.

4. Route the power cord through the cable-restraint bracket.

5. Plug the power cord into a properly grounded electrical outlet.

6. Verify that the dc power light and ac power light on the power supply are lit,

indicating that the power supply is operating correctly.

7. If you have other options to install or remove, do so now.

Removing a hot-swap power supply

If you have a hot-swap power-supply backplane and have installed power supplies, you normally have power redundancy and hot-swappability. However, if the load on your server requires the capacity of all installed power supplies, you do not have redundancy or hot-swappability and must turn off the server before removing any of your power supplies.

Attention: If you do not have power redundancy, and you remove a power supply while the system is running, your system will immediately stop working.

Hardware Maintenance Manual: Type 8668

Page 77

Removing a power supply

To remove a power supply:

1. Check the NON LED (CR24) on the diagnostics panel on the system board. a. If the NON (nonredundant) LED is lit, you do not have redundancy. Turn

off the server and peripheral devices; then, continue with step 2.

Note: The Information light on the operator information panel on the front

of the server also will be on. See “Operator information panel” on page 10 for the location and contents of the operator information panel.

b. If you have more than one power supply installed and the NON LED is not

lit, you have redundancy and do not need to turn off the server. Continue with step 2.

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

hardware.

2. Unplug the power cord from the power supply.

CAUTION: Be careful when you remove the power supply; the power supply might be too hot to handle comfortably.

4. Install a replacement power supply.

5. Plug the power cord for the power supply into the power cord connector. Then,

plug other end of the cord into a properly grounded outlet.

6. Verify that the ac power light and dc power light are lit, indicating that the power supply is operating correctly.

7. If you turned the server off in step 1a on page 69, turn on the server and peripheral devices.

Installing redundant power supply

You can build a fault-tolerant power system by upgrading to a power-sharing backplane. The power-sharing backplane replaces the standard power backplane and allows you to use up to three 250-watt hot-swap power supplies for power sharing. You can maintain a redundant configuration with two power supplies, which allows the system to continue operation even if one power supply fails. Implementing a third power supply ensures redundancy even if one power supply fails. The backplane will alert you when redundancy is lost with the two or three power supplies configuration.
