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 24.

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 that the hard wa re 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 mor e systems s haring 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:

• 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 loca te 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 mult iple er ror codes are displaye d, diagno se the firs t error code disp laye d.

3. If the computer hangs with a POST error , go to the “Chapter . Symptom-to-FRU index,” on page 215.

4. If the computer hangs and no error is displayed, go to “Undetermined problems” on page 241.

5. Power supply problems, see “Chapter . Symptom-to-FRU index,” on page 215.

6. Safety information, see “Safety information” on page 249.

7. For intermittent problems, check the error log; see “PO ST erro r me s s ages” on page 12.

Server features

The unique design of the server takes advantage of advancements in symmetric multiprocessing (SMP), data storage, and memory protection. The server combines:

• Impressive performance using an innovative approach to SMP The server supports up to four Pentium III Xeon microprocessors. The server

comes with one microprocessor installed; you can install additional microprocessor s to enhance performance and provide SMP capability.

• Integrated disk-array subsystem Although many operating systems provide software fault tolerance through

mirroring, IBM provides hardware fault tolerance through the redundant array of independent disks (RAID) controller. The IBM ServeRAID™ controller is a standard feature. It provides three channels and supports RAID levels 0, 1, 1E, 5, and 5E.

• Large data-storage an d hot- swa p cap ab ilitie s All models of the server support up to 10 slim-high or 7 half high hot-swap hard

disk drives . Th is hot-swap feature enables you to remove and replace hard disk drives without turni ng off the server.

• Hot-plug PCI adapter capabilities The server ha s f our hot-plug slots for PCI adapters. With operating system

support, you can replace failing hot-plug PCI adapters without turning off the server. If the hot-add feature is supported by the operating system and the PCI adapter, you can also add PCI adapters in these slots without turning off the server.

• Redundant cooling and power capabilities The redundant cooling and hot-swap capabilities of the fans in the server enable

continued operation if one of the fans fails, because you can replace a failing fan without turning off the server.

The server comes standard with three 250-watt power supplies, which support redundancy for a typical configuration. You can install one additional power supply.

• Large system memory The memory bus in the server supports up to 16 GB of system memory. The

memory controller provides error correcting code (ECC) support for up to 16 industry-sta ndard, 3. 3 V, 168-pin, 8-byte, register ed, dual inlin e memory modules (DIMMs). The memory controller also provides Chipkill™ memory protection. Chipkill memory protect ion is a technolo gy that protects the syste m from component fa ilure on a DIMM.

• System-management capabilities The serve r comes with a Netfinity Advanced System Management Processor.

This processor, in conjunction with the Netfinity Manager software provided on the ServerGuide CDs, enables you to manage the functions of the server locally and remotely. The Netfinity Advanced System Management Processor also provides system monitoring, event recording, and dial-out alert capability.

6 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY

Note: The Netfinity Advanced System Management Processor is sometimes

referred to as the service processor.

Refer to “Chapt er . Netfinity Manager,” on page 95 for more information.

• Integrated network environment support The server comes with an Ethernet controller. This Ethernet controller has an

interface for connecting to 10-Mbps or 100-Mbps networks. The server automatically sel e cts between 10BASE-T and 100BASE-TX. The controller provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

• Redundant network-interface card The addition of an optional, redundant network interface card (NIC) provides a

failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associ ated with thi s primary connection is automatically switched to the redundant NIC. This switching occurs without data loss and without user intervention.

• IBM ServerGuide CDs The ServerGuide CDs included with the Netfinity server provide programs to

help you set up the server and install the network operating system (NOS). The ServerGuide program detects the hardware options that are installed, and provides the correct configuration pr ogram and device drivers. In addition, the ServerGuide CDs include a variety of application programs for the server.

Reliability, availability, and serviceability

Three of the most importan t featu res in server des ign a re reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on the server; that the server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.

The following is an abbreviated list of the RAS features that the server supports.

• Menu-driven setup, syste m configu ration, RA ID configurat io n, and diagno s tic programs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the det e ction of a probl e m. See “POST” on page 12 for more information.

• Diagnostic programs and error messages

• 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 that are built into the server. By following the path of lights, you can quickly identify the type of system error that occurred. See “Light path diag nostics” on page 27 for more information.

• Error symptoms

These charts list problem symptoms, along with suggested steps to correct the problems. See the “Diagnosing errors” on page 34 for more information.

12 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY

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 series of te sts is called the power-on self-test or POST.

If POST finishes without detec ting any pr oblems, a sin gle beep sounds, the f irst sc reen of the operating system or application progr am 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 the screen. See “POST beep codes” and “POST error messages” for mo re information.

Notes:

1.If you have a pow e r-on password or ad ministrato r password set, you must type the password and press Enter, when prompted, before POST will continue.

2.A single problem might c ause 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 215.

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 “POST error codes” on page 226.

Event/error logs

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 sy stem status messages from the Netf inity Advanced System Managem ent Processor.

To view the contents of the error logs, start the Configuration/Setup Utility program; then, se l e c t Ev ent/Error Logs from the main menu.

Small computer system interface messages

If you receive a SCSI error message, see “SCSI error codes” on page 236. Note: If the server does not have a har d disk drive, ig nore any message that indicates

that the BIOS is not installed.

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

Solving ServeRAID problems

This section describes the ServeRAID text and numeric messages that might appear during startup. This section also includes some basic information about rebuilding a defunct drive .

In addition to the information provided in this section, you might want to use the ServeRAID IPSSEND program to help isolate ServeRAID problems.

ServeRAID controller messages

This section lists the ServeRAID messages that might appear during system startup. The ServeRAID cont roller s provide a Device Ev en t Log that collect s statist ics on the

number and types o f events that occur on a selected physical drive. After correct ing a problem with the array, clear the log so that you can identify any subsequent errors quickly. For information about clearing the event log, see "eraseevent" on page 170.

All physical drives contain unique identifiers, such as the drive serial number and manufacturer. During configuration, the ServeRAID controller stores this information.

ServeRAID startup messages

During power-on self-test (POST), the ServeRAID controller compares the stored configuration informa tion to the configu ration that is actually present. If a discrepancy exists, one or more status messages appear after POST completes, but before the operating system loads.

Notes:

1.When the ServeRAID controller requires your input, a list of function keys will appear below the message.

2.Where the Action information tells you to start the IBM ServeRAID configuration program, insert the IBM ServeRAID Support CD into the CD-ROM drive; then, restart the server. The Action column also provides general information about the message.

3.Where SID or ch appears in these messages, sid is the SCSI ID for the device, and ch is the channel to which the device is atta ched .

4.Where m or n appears in these messages, a number will appear in the actual message.

Following are messages associated with the ServeRAID subsystem in alphabetical order.

A new drive was instal led.

Explanation: When the ServeRAID controller detect s a new drive that is not part of the current configuration, the

following message appears: x new ready drives found where x is the number of ready drives found.

Action: This is an information message. No action is requir ed.

Configured dri ves are missing.

Explanation: When the ServeRAID controller detects t hat a pr eviously config ured drive is missing, the following

message appears: x online drives not responding where x is the number of drives not responding. Example of a possible message: Onli ne Drive on Channel 3 SCSI ID 3 is not responding.

Action: Press one of the following keys: F2 – Detailed description. Press this key for a detailed description of the problem, such as the example message ab ove. F4 – Retry. Press this key after correcting a problem. For example, press F4 after you turn on the external storage

enclosure that contains the physical drive. F5 – Change the configuration and set the drives to defunct. Press th is key to acc ept the new state that the Serve RAID controller will assign to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty. You can also press F5 when you must remove a drive. RAID level-1 and RAID level-5 logical drives are present, and performance in a degraded mode is acceptable. The ServeRAID controller will assign the drive a state of defunct, but the server c an complete startup. However, the array will remain in critical mode and the potential for data loss will exist until you replace and rebuild the defunct drive. To prevent the loss of data, replace and rebuild the defunct drive in a timel y manner.

Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before yo u

replace the drive, ensure that:

1. All cables are connected properly to the backplane and to the physical drive. Also, ensure that all cables inside the server are connected properly.

2. The hot-swap drive trays are seated properly in the drive bay.

3. Try rebuilding the drive if you have not already done so. See “Rebuilding a defunct drive” on page 22 for more information.

After you perform these steps, if the physical drive does not function properly, replace the drive. F10 – Continue booting without changing the configuration. Press this key to continue without change to the configuration.

new location, the following message appears: x online drive has been rearranged where x is the number of drives that have been rearranged. Examples of possible messages are: Online Drive on

Channel 3 SCSI ID 4 moved to Channel 3 SCSI ID 3 Online Drive on Channel 3 SCSI ID 3 moved to Channel 3 SCSI ID 4

Action: Press one of the following keys: F2 – Detailed description. Press this key for a detailed description of the problem, such as the example messages above. F4 – Retry . Press this key after correcting a problem. For example, press F4 after you move the physical drive to its previously assigned location . F5 – Change the configuration and set the drive to defunct. Press this key to accept the new state that the ServeRAID controller will assign to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty.

Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before you

replace the drive, ensure that:

1. All cables are connected properly to the backplane and to the physical drive. Also, ensure that all cables inside the server are connected properly.

2. The hot-swap drive trays are seated properly in the drive bay.

3. If you have not already attempted to rebuild the drive, try rebuilding it. See “Rebuilding a defunct drive” on page 22 for more information.

After you perform these steps, if the physical drive does not function properly, replace the drive. F6 – Cha n ge the configuration and accept the rearrangement. Press this key to modify the configuration to match the current drive location. You might remove the hot-swap drives from the server for security or maintenance reasons. If you replace the drives but install them in different drive bays, you can press F6 to accept the new locations, and the ServeRAID controller will update the configuration. F10 – Con tinu e star tu p w ith ou t chan gi n g the con f igu rat io n. Press thi s key to continue without change to the configuration.

Action: Press one of the following keys: F2 – Detailed description. Press this key for a detailed description of the problem, such as the example messages above. F4 – Retry. Press this key after correcting the prob lem. For example, press F4 after you move the physical drive to its previously assigned location, or after you install the original physical drives back in the server. F5 – Change the config ura tion and set th e dri ve to defu nct . Press this key to acc ept th e new state that the ServeRAID controller will assign to the drive. For example, t he ServeRAID controller will assi gn the drive a state of de fu n ct or em pty. Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that:

1. All cables are connected properly to the backplane or pro cessor or I/O board, and to the physical drive. Also, ensure that all cables inside the server are connected properly.

2. The hot-swap drive trays are seated properly in the drive bay.

3. If you have not already attempted to rebuild the drive, try rebuilding it. See “Rebuilding a defunct dri ve” on page 22 for more informa tion.

After you perform these steps, if the physical drive does not function properly, replace the drive. F7 – Import configuration information from drive. Press this key to restart the server. Press this key to import the configuration information from the drive and to update the configuration information for the ServeRAID controller. This choice is useful when you replace the ServeRAID controller in an existing S erveRAID subsystem. You also might press F7 if you replace a whole set of drives with drives that were configured in another server with a ServeRAID controller. When you install drives in a server that has no logical drives defined, the F7 choice will not appear. The ServeRAID controller does not contain any logical drives in its factory configuration. Therefore, F7 will not appear. In this case, do the following:

1. Restart the server and press Ctrl+I to enter the Mini-Configuration program (see “Using the ServeRAID MiniConfiguration program” on page 16 5).

Rebuil ding a defunct drive

A physical drive is defunct when there is a loss of communication between the controller and the physical drive. This can be caused by any of the following:

• An improperly connected cable, physical drive, or controller

• A loss of power to a drive

• A defective cable, backplane, physical drive or controller

In each case, the communication problem needs to be resolved, and then a rebuild operation is required to reconstruc t the dat a for the devic e in its disk array. The ServeRAID controllers can reconstruc t RAID level- 1 and RAID leve l-5 logical dr ives , but they cannot reconstruct dat a stored in RAID level-0 logical dr ives .

BCS ECS Explanation and possible recovery action

Diagnostics 23

To prevent data-integrity problems, the ServeRAID contro ller s set s the RAID level-0 logical drives to blocked during a rebuild operation. After the rebuild operation completes, you can unblock the RAID level-0 logical drives, and access them once again. Remember, however, that the logical drive might contain damaged data.

Steps for recovering from defunct drives

If the defunct drives are part of an array, do the following:

• If more than one physical drive in an array is defunct, replace DDD drives and restore from backup.

• If a rebuild operation is in progress, wait until the rebuild is complete.

• If a rebuild is not in progress and only one physical drive in the array is defunct,

replace the drive.

Rebuilding a hot-swap drive

A hot-swap rebuild r efers to a rebuild operation that is st arted by the ServeRAID controller when it detects that a drive that is part of a RAID-I or RAID-J array and in the defunct state has been removed and reinserted on the SCSI backplane. The reinsertion of the physical drive, whether it is the same drive or a new drive, will trigger the ServeRAID controller to start the rebuild operation. During the rebuild operation, the drive being rebuilt is in the rebuild state, and the logical drive remains critical until the rebuild operation has been successfully completed.

On IBM servers, when a hot-spare drive is available, the rebuild operation will begin automatically without the requirement to replace the failed drive.

To start a hot-swap rebuild, do the following:

1. Without removing the drive com ple tely, gently remove the physical drive from the server, using the handle of the hot-swap tray. If necessary, refer to the documentation that comes with your server on removing a physical dr i ve.

2. Wait 20 seconds to allow the physical drive to completely spin down. Note: When power is removed from a hot-swap drive, the drive immediately

parks the heads, locks the actuator in the "landing zone", and begins spinning down. However, the spinning down of the disk might require up to 20 seconds after powe r is remove d. Do not move the drive while it is spinning down. Moving the drive while it is spinning down may damage the drive.

3. Gently replace into the server the physical drive that you r emoved. Make sur e the drive is completel y insta lled in the bac kpla ne co nnec tor.

Recovering from an incomplete format of a physical drive

During formatting of a physical drive, if the format process is stopped by a system reset, system shut down, power outage, or by some other means, the physical drive becomes inoperable .

To enable the physical drive to communicate with the ServeRAID controller again, do the following:

1. Note the channel of the ServeRAID controller to which the physical drive is connected.

2. Note the SCSI ID of the physical drive.

24 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY

3. Use ipssend forma t to restart the format of the physical drive. The syntax is: ipssend format controller channel sid

where:

• controller is the ServeRAID controller number (1–12)

• channel is the channel number for the devic e (1, 2, or 3)

• sid is the SCSI ID for the device (0–15)

After the format is complete, the ServeRAID controller will be able to recognize the drive again.

Recovering from a failure in a failover-environment

In a failover environment, when the ServeRAID device driver is unable to send a command to the primary controller and the primary controller does not respond to a reset command, the device driver attempts to failover to the secondary controller.

Note: Loose cables or defective physical drives will not cause a failover to occur.

Replac ing a non-hot-plug controller in a failover pair

If a failed controller is not in a hot-plug PCI slot, do the following to replace it:

1. Shutdown the server.

2. Replace the failed controller.

3. Reconf igure the new controller.

Notes:

1.Be sure the firmware level of the new controller is the same as the controller you are replacing. Be sure to use the same controller name, partner name, and SCSI initiator ID for the controller you are replacing.

2.For detailed instructions, refer to the Hardware Maintenance Manual for the ServeRAID controller being serviced.

If the failed controller is in a hot-plug slot, refer to the documentation that comes with the server for instructions for replacing the controller.

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 inten ded 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 causes add i tional erro rs . In this cas e, th e se r ve r 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:

Diagnostics 25

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

where: fff is the thre e -digit functi on code that indicates 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.

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 reason 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 error occurred. This corresponds to the function code (fff) given in the previous list.

Result can be one of the fo llowing:

Passed This result occurs when the diagnosti c te st completes without any

errors.

Failed This result occurs when the diag n ostic test discovers an err o r. User Aborted

This result occurs when you stop the diagnostic test before it is complete.

Not Applicable

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

Aborted This result occurs when the test could not proceed because of the

system configuration.

Warning This result occurs when a possible problem is reported during the

Light path diagnostics

You can use the light path diagnostics built into the server to quickly identify the type of system error that occurred. Your server is designed so that LEDs remain illuminated when the server shuts down, as long as the power supplies are operating properly. This feature helps you to isolate the problem if an error causes the server to shut down.

If the system error LED (on the information LED panel) is not lit and no diagnostics panel LEDs are lit, it means that the light path diagnostics have not detected a system error.

If the system error LED (on the information LED panel) is lit, it means that a system error was detected. Check to see which of the LEDs on the diagnostics panel inside the server are lit and refer to the following table:

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 distributio n busses. Usually a short circuit will cause the power su b s ystem to shut d own because of an overcurrent condition.

A general procedure for troubleshooting power problems is as follows:

1. Power off the s y ste m and disconnect the AC cord(s).

2. Check for loose cables in the power subsystem. Also check for short circuits, for instance if there is a loose screw causing a short circuit on a circuit board.

3. Remove adapters and disconnect the cables and pow er co nnectors to all internal and external devices until system is at minimum configuration required for power on (see "Minimum operating requirements" on page 225).

4. Reconnect the AC cord and power on the system. If the system powers up 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.

To use this method it is important to know the minimum configuration required for a system to power up (see page 225). For specific problems, see “Power erro r messages” on page 237.

Temperature checkout

Proper cooling of the system is important for proper operation and system reliability. For a typical Netfinity server, you should make sure:

• Each of the drive bays has either a drive or a filler panel installed

• Each of the power supply bays has either a power supply or a filler panel installed

• The top cover is in place during normal operation

• There is at l east 50 mm (2 inches) of ventilated space at the sides of t he se rv er and

100 mm (4 inches) at the rear of the server

• The top cover is removed for no longer than 30 minutes while the server is operating

• The processor housing cover covering the proc essor and memory area is r emoved for no longer that ten minutes while the server is operating

• A removed hot-swap drive is replaced within two minutes of removal

• Cables for optional adapters are routed according to the instructions provided

with the adapters (ensure that cables are not restricting air flow)

• The fans are operati ng correctly and the air flow is good

• A failed fan is replaced within 48 hours

In addition, ensure that the environmental specifications for the system are met. See “Features and specifications” on page 3.

Diagnosing errors

To find solutions to problems that have definite symptoms, see “Error sympt o ms ” on page 225.

If you cannot find the problem there, go to “Starting the diagnost ic programs” on page 25 to test the se rver.

If you ha ve jus t ad de d new soft ware or a n ew opt ion and the se rver i s not wo rkin g, d o the following before using the error symptoms table:

• Remove the software or dev ice that you just added.

• Run the diagnostic tests to determine if the serve r is running correctly.

• Reinstall the new softwa re or new device.

Troubleshooting the Ethernet controller

This section provides troubleshooting information for problems that might occur with the 10/100 Mbps Ethernet controller.

Network connection problems

If the Ethernet cont roller cannot connec t to the network, check the following:

• Make sure that the cable is installed correctly. The network cable must be sec urely att a ched at all connections. If the cable is

attached but the problem persists, try a different cable.

If you set the Ethernet contr oll er to operate at 100 Mbps, you must use Cate gory 5 cabling.

Diagnostics 35

If you directly connect two workstations (without a hub), or if you are not using a hub with X ports, use a crossover cable.

Note: To determine whether a hub has an X port, check the port label. If the label

contains an X, the hub has an X port.

• Determine if the hub supports auto-negotiation. If not, try configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.

• Check the Ethernet controller lights on the operator information panel. These lights indicate whether a problem exists with the connector, cable, or hub. — The Ethernet Link Status light illuminates when the Ethernet controller

receives a LINK pulse from the hub. If the light is off, there might be a defective connector or cable, or a problem with the hub.

— The Ethernet Transmit/Receive Activity light illum inat e s when the Ethe rnet

controller sends or receives data over the Ethernet Network. If the Ethernet Transmit/Receive Activity light is off, make sur e that the hub and network are operating and that the correct device drivers are loaded.

— The Ethernet Speed 100 Mbps light illuminates when the Ethernet controller

LAN speed is 100 Mbps.

• Make sure that you are using the correct device drivers, supplied with the server.

• Check for operating system-specific causes for the problem.

• Make sure that the device drivers on the client and server are using the same

protocol.

• Test the Ethernet controller. How you test the Ethernet controll er depends on which operating system you are

using (see the Ethernet controller device driver README file).

Ethernet controller troubleshooting chart

You can use the following troubleshooting chart to fi nd sol u ti ons to 10/100 Mbps Ethernet controller problems that have definite symptoms.

Table 2. Ethernet troubleshooting chart.

Ethernet controller problem Suggested Action

The server stops running when loading device drivers.

The PCI BIOS interrupt settings are incorrect.

Check the following:

• Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also assigned to another device in the Configuration/Setup Utility program.

Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet controller or the other device. For example, for NetWare Versions 3 and 4 it is recommended that disk controllers not share interrupts with LAN controllers.

• Make sure that you are using the most recent device driver available from the World Wide Web.

• Run the network diagnostic program.

• T h e fu nc ti o n of thi s LE D can be ch a n ged by de vice driv er lo ad paramete r s. If

necessary, remove any LED parameter settings when you load the device drivers.

Data is incorrect or sporadic. Check the following:

• Make sure tha t you are using Category 5 cabling when operating the server at 100 Mbps.

• Make sure that the cables do not run close to noise-inducing sources like fluorescent lights.

The Ethernet controller stopped working when another adapter was added to the server.

Check the following:

• Make sure that the cable is connected to the Ethernet controller.

• Make sure that the PCI system BIOS is current.

• Reseat the adapter.

• Determine if the interrupt (IRQ) setting assigned to the Ethernet ada pter is also

assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not

function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet adapter or the other device.

The Ethernet controller stopped work ing without apparent cause.

Check the following:

• Run diagnostics for the Ethernet controller.

Working inside the server with the power on

The server is designed with features that make it highly available. These features are hot-add and hot-plug devices. Hot-plug devices allow you to replace the device without turning off the server. Hot-add devices allow you to add an identical device without turning off the server. In the past you would need to turn off the server and disconnect power to perform these operations. With the hot-plug features, you can remove the top cover of the server with the power on.

The server supports hot plug, hot add, and hot swap devices and is designed to operate safely while turned on wit h the top cover removed. The server i s d esigne d to protect you and the server. Follow these guidelines when you work inside a server that i s turned o n :

• Avoid loose-fittin g clothing on your forearms. Button long-slee ve d shirts before working inside the server; do not wear cuff links while you are working inside the server.

• Do not allow your necktie to hang inside the server.

• Remove jewe lry, such as bracelets, necklaces, rings, and loos e -fitting wr ist

watches.

• Remove items from your shirt pocket (such as pens or pencils) that could fall into the server as you lean over it.

• Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or screws, i nt o the serv e r.

Removing the server top cover and bezel

Before you begin:

• Read “Safety information” on page 249.

Working with adapters

You can install up to six PCI adapters in the expansion connectors on the processor board. All six of the slots are peripheral component interconnect (PCI) expansion slots.

The server comes with an integrated super vid e o gr ap hics array (SVGA) video controller, which is not removable. If you want to disable this controller and use a video adapter instead, you can install a video adapter in an expansion slot. When you install a PCI video adapter, the server BIOS automatically disables the integrated video controller.

Note: Video adapters are supported in all six PCI slots. The following illustration shows the location of the 64-bit PCI expansion slots on the

processor board. Note: The illustrations in this book might differ slightly from your hardware.

Adapter considerations

Before you continue wi th the adapter- installation procedure:

• Review the documentation that comes with the adapter and follow those instructions in addition to the instructions given in thi s chapter. If you need to change the switch or jumper settings on the adapter, follow the instructions that come with th e adapter docum e ntation.

• Slots 3 through 6 support 5.0V, 3.3V, and universal PCI adapters. Note: Universal PCI adapters support both 3.3V and 5.0V operation.

• Slots 1 and 2 support 3.3 V and univers al non-h ot-swap PCI adapters only.

• 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 system scans PCI slots 1 through 6 to assign syste m resources; then the system starts (boots) the PCI devices in the following order: processor board devices, slo ts 1 and 2, and then slots 3 through 6.

• The performance of the PCI adapters depends on the types of adapters in the system.

Installing a hot-plug adapter

Refer to the following illustration to install a hot-plug PCI adapter.

Note: The illustrat ions in this book may be slightly different from your server. Before you begin:

Installing internal drives

If you add different types of drives, the system can read multiple types of media and store more data. Several types of drives ar e availabl e, such as:

• Diskette

• Hard disk

• CD-ROM

• Tape

Internal drives are installed in bays. Your server comes with one 3.5-inch, 1.44 MB diskette dr ive an d one IDE CD-ROM dr ive.

Installing options 67

򐂰1򍦠 3.5 inch diskette drive 򐂰2򍦠 CD-ROM drive 򐂰3򍦠 Media bays 1 and 2 򐂰4򍦠 Hot-swap hard disk

Your server contains hardware that enables you 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.

Each hot-swap drive has two indicator lights on the front of the server. If the amber hard-disk status light for a drive is lit continuously, that individual drive is faulty and needs to be replaced. When the hard-disk status light indicates a drive fault, you can replace a hot-swap drive without turning off the server.

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 a ttachment (SCA) co nn ector. Hot-swapdrive trays come with hot-swap drives.

Internal drive bays

Internal drives are installed in bays.

• Your server comes with one CD-ROM drive and one 3.5-inch, 1.44 MB diskette drive.

• The left front bays support 5.25-inch, half-high, removable-media drives. Any two adjacent 5.25-inch, half-high bays can be converted to a single full-high bay.

Note: The server EMI integrity and cooling are both protected by having the left

front bays 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 anothe r.

• Y ou cannot install hard disk drives in the left front bays. You can install hot-swap hard disk drives only in the hot-swap hard disk d rive bays on the ri ght fron t side of the server.

68 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY

• If you are installing a device with a 50-pin connector in one of the left front bays,

you will need a 68-to-50-pin converter (option number 32G3925).

• Your server su pports ten 1-inch (26 mm) slim-high or se ven 1.6-inch (42 mm) half high, 3.5-inch hot-swap hard disk drives in the hot-swap bays.

• The hot-swap b a ys connect to a hard disk drive backplane. The backplane is a printed circuit board behind the bays.

Some drives have a special interface called small computer system interface, or SCSI. Using this interface, you can attach multiple drives to a single SCSI controller.

Notes:

1.Any information abo u t SCSI drives also applies to other SCSI devices, such as scanners and printers .

2.If you plan to install both internal and external SCSI devices, you must follow the instructions in “Connecting external options” on page 81, in addition to the instructions in this section.

A 16-bit (wide) low voltage differential (LVD) SCSI cable connects the hard disk drive backplane to the ServeRaid adapter located in a PCI slot on the processor board. An additional 16-b it, two - drop SCSI cable comes with the ser ver. It is located in the bottom of the server media bay and is restrained with a cable clamp.

If you want to install SCSI devices in the removable media bays:

1. Locate the internal SCSI connector on the power backplane.

2. Use the 16-bit two-d rop SCSI cable located in the bottom of the se rver media bay.

3. Connect the SCSI device(s) in the r e movable media ba y to the internal SCSI connector on the power backplane.

Installing a hot-swap hard disk drive

Refer to the following illustration when installing a hot-swap drive.

Before you begin:

• Read “Safety information” on page 249.

• Review the information in “Before you begin” on page 60.

• Read the documentation that comes with the option.

Installing options 69

Note: You do not have to turn off the server to install hot-swap drives in these bays. To ins tall a drive in a hot-sw ap bay:

1. Review the information in “Before you begin” on page 60.

2. Remo ve 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 th e se rver.

Attention: To maintain proper system cooling, do not operate the server for

more than 10 minutes without either a drive or a filler panel installed for each bay.

3. Install the hard disk drive in the hot-swap bay: a. If there is a small gap above or below the drive, separate the slim filler from

the filler panel, and insert it in the gap. Note: A drive placement guide is located on the inside edge of the bezel. The

drive placement guide indicates the placement for slim-high and half-

high drives. The guide also shows the SCSI ID assigned to the drive. b. Ensure the tray handle is open (that is, perpendicular to the drive). c. Align the drive assembly with the guide rails in the bay. d. Gently push the drive assembly into the bay until the drive stops. e. Push the tray handle to the closed (locked) position. f. Check the hard disk dr ive status indicators to verify that the hard disk drive

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

individual drive is faulty and needs to be replaced. If the green hard-disk activity light is flashing, the drive is being ac cess ed.

Note: Because the server has a RAID controller installed, you must configure the

disk arrays after installing hard disk drives. Refer to “Chapter . Installing and configuring ServeRAID controllers,” on page 139 for information.

SCSI cabling requirements

If you plan to attach external SCSI devices, you must or der additional SCSI cables. To select and o rd er th e correct ca bl es fo r u se with exte rna l devices, co n t a ct you r IB M reseller or IBM marketing representative.

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 standa rds will help ensure that the server operates properly.

Setting SCSI IDs

Each SCSI device connected to a SCSI co ntroller must have a unique SCSI ID. This ID enables the SCSI controller to identif y the device and ensure that different devices on the same SCSI channel do not atte mp t to transfer da ta simultaneou sly. SCSI devices that are connected to different SCSI channels can have duplicate SCSI IDs.

The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive bays. However, when you attach SCSI devices to the external SCSI connector, you must set a unique ID for the device. Refer to the information that is provided with the device for instructions to set its SCSI ID.

Serial-port connectors

The following table shows the pin-number assignments for the 9-pin, male D-shell serial-port connectors on the rear of the server. These pin-number assignments conform to the industry stan dard.

Universal Serial Bus ports

The server has two Universal Serial Bus (USB) ports that configure automatically. USB is an emerging serial interface standard for te lephony and multimedia devic es. It uses Plug and Play technology to determine the type of device attached 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 keyboa rd emulates a mouse and you will not be able to disable the mouse settings in the Configuration/ Se tup Ut ility program .

3.Check to make sure your NOS supports USB devices.

USB cables and hubs

You need a 4-pin cable to connect devices to USB 1 or USB 2. If you plan to attach more than two USB devices t o the machine, you mu st u se a hub to connect the devices. The hub provides mu ltiple co nn e ctors for attac hing additional external US B devices with a maximum of 127 external 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.

Installing options 89

USB-port connectors

Each USB port has an external connector on the rear of the server for attaching USB compatible dev ices .

The following table shows the pin-number assignments for the USB-port connectors on the rear of the server.

Ethernet port

Your server comes with an integrated Ethernet controller. This controller provides an interface for connecting to 10-Mbps or 100-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

To access the Ethernet port, connect a Category 3, 4 or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of the server.

Note: The 100BASE-TX Fast Ethernet standard re q u ires that the cabling in the

network be Category 5 or higher.

Configuring the Ethernet controller

When you connect the server to the network, the Ethernet controller automatically detects the data-transfer rate (10Mbps or 100Mbps) on the network and then sets the controller to operate at the appropriate rate. That is, the Ethernet controller will adjust to th e network data rate, whether the data rate is stand a rd Ethernet ( 10BASET), Fast Ethernet (100BASE-TX), half duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

The Ethernet controller is a PCI Plug and Play device. You do not need to set any jumpers or configure the controller for the operating system before you use the Ethernet controller . However, you must install a device driver to enable the operating system to address the Ethernet controll er. The device drivers are provide d on the ServerGuide CDs.

Failover for redundant Ethernet

The IBM Netfinity 10/ 100 Fa ult Tolerant Adapter is an optional redundant netw ork interface card (NIC adapter) that you can install in the server. If you install this NIC adapter and connect it to the same logical LAN segment as the primary Ethernet controller, you can configure the server to support a failover function. You can configure either the integrated Ethernet controller or the NIC adapter as the primary Ethernet controller. In failover mod e, if the primar y Etherne t controlle r detects a link failure, all Ethernet traffic associated with it is switched to the redundant (secondary) controller. This switching occurs without any user intervention. When the primary link is restored to an operational state, the Ethernet traffic switches back to the primary Ethernet controller. The switch back to the primary Ethernet controller can be automatic or manually controlled, depending on the setup and operating system.

Table 16. USB-port connector pin-number assignments.

Pin Signal

1VCC 2-Data 3+Data 4Ground

90 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY

Note that only one controller in the redundant pair is active at any given time. For example, if the primary Ethernet controller is active, then the secondary Ethernet controller cannot be used for any other network operation.

Note: The operating system determines the maximum number of IBM Netfinity

10/100 Fault Tolerant Adapters that you can install in the server. See the documentation tha t comes with the adapter for more information .

Considerations when combining failover and hot-plug func tions: If the operating system supports hot-plug PCI adapters and the optional

redundant NIC adapter is installed in a hot-plug PCI slot, you can replace the NIC adapte r without po wering off the server — even if it is the primary Ethernet controller. Disconnecting the Ethernet cable from the primary Ethernet controller will cause th e Et hern et traf f ic t o s witc h auto mati cal ly to th e sec ond ary E ther ne t con tr ol ler. This can be very useful if a faulty adapter causes a network problem, or if you want to upgrade the primary adapter hardware.

Note: If you hot replace the primary adapter while the Ethernet traffic is being

handled by the secondary Et her net cont roller, the traffic does not automatically switch back to the primary adapter when the primary adapter comes bac k online. See “Configuring for failover”.

Configuring for failover: The failover feature currently is supported by OS/2™, Windows NT Server, and IntraNetWare. The setup required for each operating system follows.

Windows NT Server: IBM offers hot-plug support for Windows NT Server Version 4.0. Failover can work in conjunction with hot-plug support or independently. If you are not using hot-plug support, go to “Windows NT Se rv e r f ailove r se t u p ” on page 91.

Windows NT Server hot-plug setup: IBM Netfinit y Ho t Plug PCI for Windows NT Server 4.0 package is available for download from the IBM Web site at:

http://www.pc.ibm.com/support

Enter the brand type of Server, click on D ownloadable files and look for Hot Plug. The IBM Netfinity Hot Plug PCI for Windows NT Server 4.0 package uses the Intel Desktop Management Interface (DMI) to control hot-plug support for the Ethernet controllers. The Ethernet controller in the computer is DMI compliant. Download and install the following software in the order listed:

1. IBM Netfini ty PCI Hot plug for Windows NT 4.0 Failover DM I Agent

2. IBM Netfinity PCI Hot Plug for Windows NT 4.0 Sol u tion

3. IBM Netfinity 10/100 Fault Tolerant Adapter device drivers

Note: The order of installation is important. You must install the IBM Netfinity Hot

Plug for Windows NT Server 4.0 package before you install the IBM Netfin ity 10/100 Fault Tolerant Adapter driver. If you install the adapter device driver before the PCI Hot Plug Solution package, the adapter device driver will not recognize the hot-plug code. This happens because the adapter device driver only checks the NT registry for the Hot Plug pack ag e during ins tallat ion. If the PCI Hot Plug Solution package is added after the adapter device driver is installed, the adapter must be removed and added again in order for it to detect the P CI Ho t-Plu g So l u t ion code .

To ins tall the IBM Netfin ity PCI Hotp lug for Windows NT 4.0 Failover DMI Agent :

1. Download the IBM Netfinity PCI Hotplug for Windows NT 4.0 Failover DMI Agent DMI Agent file from the Netfinity Support web page and extract the files onto a diskett e .

2. Insert the diskette into the diskette drive.

3. From the Start menu, select the Run opt ion.
