General checkout

The server diagnostic programs are stored in flash RAM on the I/O function card. These programs are the primary method of testing the major components of the server. You can also use them to test some external devices.

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.

Note

Some error conditions will generate error messages that are displayed in the front panel video fluorescent display (VFD). Some of these messages will automatically be cleared once the problem is corrected. Others will need to be cleared manually. To ensure you have correctly identified the failing FRU during your diagnosis, manually clear any messages from the front panel display using the scroll and enter buttons on the right side of the front panel after you have replaced any FRU(s). This can be done with the system in the Standby mode before power up. Then, once you reboot the system, if a problem still exists which normally generates a message on the front panel, the new message generated will alert you to the continued or new error condition.

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:

 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 systems are located near the failing

system.

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

12. If you have a SMI error posted in the front panel, see “System Management Interrupt (SMI) Handler” on page 227.

13. If your system is hung, will not boot, or exhibits symptoms other than those above, see “Undetermined problems” on page 211.

14. 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.

15. If multiple error codes are displayed, diagnose the first error code displayed.

16. If there are multiple errors logged in the system error log, diagnose the errors in the order they were posted according to the date/time stamp.

17. If you have intermittent problems, check the system error log; see, “System error log” on page 32.

18. If you need safety information, see “Safety information” on page 240.

Netfinity 8500R - Type 8681 7

Diagnostics

Server problems can be caused by hardware, software, or a user error. An example of a user error is pressing the wrong key on the keyboard.

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

 Diagnostic programs

 Power-on self-test (POST)  POST beep codes

 Error messages

 System error log

 Option diskettes

Diagnostic programs: The Diagnostics Utility

program contains several server diagnostic programs. These diagnostic programs are stored on electrically erasable programmable read-only memory (EEPROM). These programs are the primary method of testing the major components of your server and some external devices.

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.

Note

Power-on self-test (POST): 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.

POST does the following:

 Checks the operation of some basic I/O function card,

processor daughterboard, and I/O board operations

 Checks the memory  Compares the current server configuration with the

stored server configuration information

 Configures PCI adapters  Starts the video operation  Verifies that drives (such as the diskette, CD-ROM,

and hard disk drives) are connected properly

8 Netfinity Server HMM

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

While the memory is being tested, the amount of available memory appears on the screen. These numbers advance as the server progresses through POST and the final number that appears on the screen represents the total amount of memory available. If POST finishes without detecting any problems, a single beep sounds and the first screen of your operating system or application program appears.

If POST detects a problem, more than one beep sounds, or an error message appears on your screen.

Note

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 usually will not occur the next time you run the test.

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.

 No beep indicates that a unrecoverable error occurred

during POST.

 More than one beep indicates that POST detected a

problem. For more information, see “Beep symptoms” on page 167.

Error messages: 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 indicated by error messages should be performed by trained service personnel.

Hardware error messages that occur can be text, numeric, or both. Messages generated by your software generally are text messages, but they also can be numeric.

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 more information, see “Viewing the test log” on page 14.

System-monitoring messages:

System-monitoring messages occur as the Advanced System Management PCI Adapter monitors critical system functions.

Netfinity 8500R - Type 8681

DIAGNOSTIC PROGRAMS

Diagnostic error messages: Diagnostic error

messages occur when a diagnostic test finds a problem with the server hardware. These error messages are alphanumeric and they are saved in the test log. For more information, see “Viewing the test log” on page 14.

Software-Generated error messages: These

messages occur if a problem or conflict is found by an application program, the operating system, or both. Messages are generally text messages, but they also can be numeric. For information on these error messages, refer to the documentation that comes with your software.

POST error log

The POST error log contains a maximum of three error and warning messages issued during POST and all system status messages from the Advanced System Management PCI Adapter (service processor). See “POST error log” on page 32 for information on how to view the POST error log.

System error log

The system error log contains all error and warning messages issued during POST, all system status messages from the Advanced System Management PCI Adapter (service processor), and all error messages issued during diagnostic testing. See “System error log” on page 32 for information on how to view the system error log.

Option diskettes

An optional device or adapter can come with an Option Diskette. Option Diskettes usually contain option-specific diagnostic test programs or configuration files.

If your optional device or adapter comes with an Option Diskette, follow the instructions that come with the option. Different instructions apply depending on whether or not the Option Diskette is startable.

Diagnostic programs

This section includes useful information on running the diagnostic programs. These programs are designed to test the IBM Netfinity 8500R server. If you want to test a non-IBM product, refer to the information that comes with that product.

10 Netfinity Server HMM

DIAGNOSTIC PROGRAMS

Notes

1. 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 usually will not appear the next time that you run the test.

2. You can also run the diagnostic programs remotely with the Advanced System Management PCI Adapter in conjunction with the Advanced System Management service capabilities of Netfinity Manager, a terminal program, or a Web browser. Refer to the “Advanced System Management Information” section of this

Library

for more information.

Server

Running the diagnostic programs: While you

are running the diagnostic programs, pressing F1 displays help information. Pressing F1 from within a help screen provides a help index from which you can select different categories. Pressing Esc closes the Help window and returns to running the diagnostic programs.

Netfinity 8500R - Type 8681

Notes

1. To run the diagnostic programs, you must start the server with the highest level password.

That is, if you enter the power-on password and an administrator password is set, you cannot run the programs. You can only view the error messages in the Test Log.

You must enter the administrator password to run the diagnostic programs.

2. If the server stops during testing and you cannot continue, restart the server and try running the diagnostic programs again. If the problem persists, have the system serviced.

3. If the diagnostic tests do not find a problem, but the problem persists during normal operations, see “Undetermined problems” on page 211 and look for the problem symptom.

4. You might have to install a wrap connector on your active parallel or serial port to obtain accurate test results for these ports. If you do not have a wrap connector, contact your IBM reseller or IBM marketing representative.

5. You might need a scratch diskette to obtain accurate test results when testing the diskette drive.

6. The keyboard and mouse (pointing device) tests assume that a keyboard and mouse are attached to the server.

DIAGNOSTIC PROGRAMS

Starting the diagnostic programs: To start the

diagnostic programs:

1. Ensure that there is no diskette in the diskette drive. If the diskette drive contains a diskette, remove it.

2. Turn on the server and watch for the IBM logo screen. If the server is turned on already, shut down your operating system and restart the server.

3. After you start the server, several prompts appear on the IBM logo screen. When the prompt Press F2 for Diagnostics appears, press F2.

If a power-on password or administrator password is set, the server prompts you for it. Type in the appropriate password; then, press Enter.

The Diagnostics Utility program window appears. After you start the Diagnostics Utility program, the

following menu headings will appear at the top of the screen:  Extended  Basic  Utility  Hardware Info  Quit

Configuration overview

You play a key role in how the server allocates resources to organize and interconnect hardware devices and software programs. This allocation process is referred to as

configuration.

server depend on the number and types of devices and programs that you install.

The server supports PCI adapters and SCSI devices. Because of this flexibility, you can choose from among many adapters and devices.

In general, the greater the number and variety of hardware devices and software programs that you install in the

Netfinity 8500R - Type 8681 19

The steps required to configure the

server, the more you will have to interact with the server and the devices to correctly configure the system.

The server comes with the following hardware configuration programs:

 Configuration/Setup Utility

With the built-in Configuration/Setup Utility program, you can configure I/O functions, such as serial and parallel port assignments; change interrupt request (IRQ) settings; and change the startup sequence for drives that you install. You also can use this program to set passwords for starting up the server and accessing the Configuration/Setup Utility program.

 SCSISelect Utility

With the built-in SCSISelect Utility program, you can configure the SCSI devices that you attach to the SCSI controller. You can use SCSISelect to change default values, resolve configuration conflicts, and perform a low-level format on a SCSI hard disk drive.

Before installing a new device or program, read the documentation that comes with it. Reading the instructions helps you to determine the steps required for installation and configuration. The following actions are typically, but not always, required to configure the server.

1. Run the Configuration/Setup Utility program and record the current configuration settings.

2. Set jumpers or switches on server components. See “Jumper settings” on page 125 and “I/O function card jumpers” on page 121.

3. Set jumpers or switches on the device. See the device installation instructions.

4. Install the device in the server. See “Preparing to install options” on page 134.

5. Install software programs. See the installation instructions that come with the software.

6. Resolve configuration conflicts. See “Resolving configuration conflicts” on page 34.

The Configuration/Setup Utility program

For most configurations, the server will operate using the default system settings. You need to change the settings only to resolve configuration conflicts or to enable or change device functions (for example, defining diskette types, and so on).

When you want or need to change the default settings, the Configuration/Setup Utility program provides a convenient way to display and change the settings.

After you run and exit from the Configuration/Setup Utility program, configuration information is stored in electrically erasable programmable read-only memory (EEPROM).

20 Netfinity Server HMM

While the server is off, the configuration information remains available for the next system startup.

Always run the Configuration/Setup Utility program if you add, remove, or relocate any hardware option, or if you receive an error message instructing you to do so. Review this chapter and the information that comes with the option before making changes. Also, record the current settings before making any changes.

Attention

Maintaining a record of the configuration information is especially important if you need to move the Clear CMOS register contents jumper, which erases all configuration information (see “I/O function card jumpers” on page 121 for details).

To start the Configuration/Setup Utility program:

1. Ensure that there is no diskette in the diskette drive. If the diskette drive contains a diskette, remove it.

2. Turn on the server and watch for the IBM logo screen.

If the server is turned on already, shut down the operating system and restart the server.

3. After you start the server, several prompts appear on the IBM logo screen. When the prompt Press F1 for Configuration/Setup appears, press F1.

The Configuration/Setup Utility main menu appears. For information on the menu, see “Using the Configuration/Setup Utility main menu.”

Note

If you enter the power-on password and an administrator (supervisor-level) password is also set, a limited version of the menu appears. To see the full menu, you must restart the server and enter the administrator password when you are prompted to enter a password. See “System security” on page 24 for additional information.

Using the Configuration/Setup Utility main menu

From the Configuration/Setup Utility main menu, you can select settings that you want to change. The Configuration/Setup Utility main menu is similar to the following screen.

Note

The choices on some menus might differ slightly, depending on the BIOS version that comes with the server.

Using the System Partition

The IBM ServerGuide program creates a 50 MB logical partition on the default hard disk drive. This partition is known as the System Partition. On some Netfinity server models, the System Partition provides server-specific utility programs, such as the Service Processor DOS Utility Program. The System Partition Main Menu displays the programs available for the server model. The System Partition is a recent enhancement for the Netfinity server products.

Notes

Configuring options

Before installing a new device or program, read the documentation that comes with it. Reading the instructions helps you to determine the steps that are required for installation and configuration. The following list provides a preview of the actions that might be required to configure the server.

Netfinity 8500R - Type 8681

1. Run the Configuration/Setup Utility program and record the current configuration settings. See “The Configuration/Setup Utility program” on page 20.

2. Set jumpers or switches on the server components. See “Jumper settings” on page 125 and “I/O function card jumpers” on page 121.

3. Set jumpers or switches on the device. See the instructions that come with the adapter.

4. Install the adapter in the server. See “Adapters” on page 43.

5. Install software programs. See the installation instructions that come with the software.

6. Resolve configuration conflicts. See “Resolving configuration conflicts.”

Resolving configuration conflicts

The resources used by the server consist of interrupt requests, direct memory access (DMA), I/O ports addresses, and memory. This information is useful when a resource configuration conflict occurs.

Conflicts in the configuration occur if:

 A device is installed that requires the same resource

as another device. (For example, a conflict occurs when two adapters try to write to the same address space.)

 A device resource is changed (for example, changing

jumper settings).

 A device function is changed (for example, assigning

COM1

to two serial ports).

 A software program is installed that requires the same

resource as a hardware device.

The steps required to resolve a configuration error are determined by the number and variety of hardware devices and software programs that you install. If a hardware configuration error is detected, a message appears after the server completes POST and before the operating system is loaded. You can bypass the error by pressing Esc while the error message is displayed.

The Configuration/Setup Utility program configures the system hardware and PCI IRQs. The program does not consider the requirements of the operating system or the application programs. See “Resolving software configuration conflicts” on page 35 for additional information.

configuration error

Resolving hardware configuration conflicts: Use the following information to help resolve

hardware configuration conflicts:

1. Run the Configuration/Setup Utility program to view and change resources used by the system functions

34 Netfinity Server HMM

and the installed options. Record the current settings before making any changes. (See “The Configuration/Setup Utility program” on page 20 for instructions.)

2. Determine which adapter or device is causing the conflict. (See “Symptom-to-FRU index” on page 166 for instructions.)

3. Change adapter jumpers or switches. Some devices use jumpers and switches to define the system resources that the devices need. If the settings are incorrect or set to use a resource that cannot be shared, a conflict occurs and the device will remain deactivated by the configuration program.

4. Change system jumpers or switches. See “Jumper settings” on page 125.

5. Remove the device or adapter. Some configurations are not supported. If you must remove an adapter, see “Adapters” on page 43.

Resolving software configuration conflicts:

The memory-address space and IRQs used by some hardware options might conflict with addresses defined for use through application programs or the expanded memory specification (EMS). (EMS is used only with DOS.)

If a conflict exists, one or more of the following conditions might exist:

 The system cannot load the operating system.  The system does not work.  An application program does not operate, or it returns

an error.

 Screen messages indicate a conflict exists.

To resolve conflicts, you can change the software or hardware configuration.

Note

Start the Configuration/Setup Utility program to view the addresses used by the server functions. (See “The Configuration/Setup Utility program” on page 20 for instructions.)

The best way to resolve memory-address conflicts is to change the addresses used by the application program or the device driver. You can use the Configuration/Setup Utility program to change addresses.

If a device driver is causing a memory-address conflict, refer to the operating-system documentation or the documentation that comes with the device drivers.

Netfinity 8500R - Type 8681

Using the SCSISelect Utility program

Note

If the server has a redundant array of independent disks (RAID) adapter installed, use the configuration method that comes with the RAID adapter to view or change SCSI settings for attached devices.

Adapters

You can add adapters to extend the capabilities and power of the server.

You add the adapters to the expansion connectors, called slots, on the I/O board of the server. All slots are PCI expansion slots. The server supports up to 12 adapters in the PCI slots. There are two additional dedicated slots for the I/O function card and the Advanced System Management PCI adapter.

You can install a new PCI adapter or replace an existing PCI adapter with the same type of adapter without turning the server power off and restarting the system. These slots are called referred to as hot-plug PCI slots.

A PCI adapter comes with built-in identification and configuration specifications (set in memory on the device) that provide installation information to the server during startup. This information is read by the input/output (I/O) bus and interpreted by the server BIOS. The BIOS routines automatically configure the adapter around the resources already in use by other devices.

The server comes with a video controller. This video controller is an integrated component on the I/O function card. The integrated video controller has super video graphics array (SVGA) technology.

PCI slot LED descriptions: Each PCI slot has

two lights associated with it — one Attention/Fail light and one Power On light.

 Power On Light: This light is on when the PCI slot

is active and has power. Do not add or remove an adapter from the PCI slot when the Power On light is on. When this light is off, the PCI slot is inactive and has no power applied. You can install or remove an adapter when the Power On light is off. Refer to the operating-system documentation to determine if the operating system supports hot-plug PCI adapters.

 Attention/Fail Lights: These are bi-color lights.

When an Attention/Fail light flashes green, it indicates the PCI Hot-Plug Attention function. The meaning of

44 Netfinity Server HMM

the Attention light is defined by the operating system. Refer to the operating-system documentation to determine if the operating system supports hot-plug PCI adapters and, if so, what the Attention light indicates. When this light is solid amber, it indicates a failure on the PCI adapter installed in the slot.

Adapter considerations: Before you continue with

the adapter-installation procedure:

 Review and follow the instructions that come with the

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

 Manual assignment of interrupts is never required

with operating systems that use the Advanced Programmable Interrupt Controller (APIC) interrupt structure. Although you can manually assign interrupts through the Configuration/Setup utility program, most adapters designed for PCI slots are auto-configuring. If the required resources are available, the BIOS software automatically configures an adapter around the resources already in use by other devices. The default setting is generally the most appropriate. If you choose to manually assign interrupts, be sure that these interrupts do not conflict with existing values. If a conflict does occur, see “Resolving configuration conflicts” on page 34.

 For a list of compatible RAID adapters, and

installation requirements, refer to http://www.ibm.com/pc/us/compat/ on the World Wide Web. If you install a RAID adapter, configure the adapter using the RAID adapter documentation.

 The I/O function card slot can support only the I/O

function card. It is not an expansion slot.

 The Advanced System Management PCI adapter slot

can support only the Advanced System Management PCI Adapter. It is not an expansion slot.

Attention

You must have the Advanced System Management PCI Adapter installed for proper operation of the server and to use the system-management functions that the adapter provides. See “Understanding the Netfinity 8500R server design” on page 163 for more information about the Advanced System Management PCI Adapter.

The integrated video controller 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

Netfinity 8500R - Type 8681 45

slot. If you want a monitor to be the startup monitor, install a video adapter in slot 10, 11, or 12. When you install a PCI video adapter in one of these slots, the server BIOS automatically disables the integrated video controller.

Table 1 contains information on the requirements for the PCI adapter slots and PCI buses in the server.

Table 1. PCI adapter information

Notes:

1. All expansion slots are hot-plug, 64-bit, PCI slots.

2. You can install: a. A full-length or half-length, 32-bit or 64-bit, 5 V or Universal,

hot-plug or non-hot-plug PCI adapter in slots 1–5 or 10–12. 66 MHz PCI adapters plugged into these slots will operate at 33 MHz.

b. A full-length or half-length, 32-bit or 64-bit, 3.3 V or Universal,

hot-plug or non-hot-plug PCI adapter in slots 6–7 and 8–9. A 33 MHz PCI adapter installed in one of these slots limits a 66 MHz PCI adapter installed on the same bus to 33 MHz.

3. To optimize performance, spread the installation of high-speed

adapters, such as 66 MHz Ethernet adapters, between the two 66 MHz PCI buses.

keying

Configuring adapters: PCI devices automatically

communicate with the server configuration information. This usually results in automatic configuration of a PCI device. From the Configuration/Setup utility program, you can select available resources for the adapter that you are installing. If a conflict does occur, see “Resolving configuration conflicts” on page 34.

Refer to the documentation that comes with the adapter for information about required system resources. Then, make the appropriate jumper or switch settings on the adapter.

46 Netfinity Server HMM

Advanced System Management PCI adapter

With a Advanced System Management PCI adapter, in conjunction with Netfinity Manager, you can locally and remotely configure and monitor many features of the server.

Attention

The server must have the Advanced System Management PCI Adapter installed for proper server operation and to use the system-management functions that the adapter provides.

The Advanced System Management PCI Adapter contains the connectors for the 10/100 Mbps Ethernet port, dual serial port, Advanced System Management Interconnect bus, Personal Computer Memory Card International Association (PCMCIA) token-ring, and the I/O function card.

DIMM and memory board installation

You can increase the amount of memory in the server by installing additional The server uses 100 MHz, 168-pin, PC100 registered synchronous dynamic random-access memory (SDRAM), industry-standard DIMMs with error checking and correction (ECC). You can add extra DIMMs or replace existing DIMMs. The illustration 66 shows how DIMMs are installed.

dual inline memory modules (DIMMs)

Netfinity 8500R - Type 8681 63

Notes

1. You can install an optional memory board that contains an additional 16 DIMM connectors and supports cache-line interleaving. To obtain an optional memory board, contact an IBM reseller or IBM marketing representative.

2. The connector identifiers on both the standard and the optional memory boards are J1–J16. To distinguish the two memory boards, use the labels provided on the processor housing assembly. These labels refer to the connector identifiers as A1–A16 on the standard memory board (A), and B1–B16 on the optional memory board (B).

3. The server comes with a system label on the server cover. The numbers located to the right of the memory boards on the system label do not indicate DIMM connector identifiers. These numbers indicate the DIMMs; for example, .1/ means the first DIMM that you install, .9/ means the ninth DIMM that you install, and so on.

Cache-line interleaving

can only occur if two memory boards are installed in the server. This process allows the two memory boards to share a common address range, with one memory board responding to even-numbered cache lines, and the other memory board responding to odd-numbered cache lines. This configuration has the highest performance because it allows the two SDRAM arrays to be used in a balanced fashion, reducing access conflicts.

5. Installing or removing DIMMs changes the server configuration. Therefore, after installing or removing a DIMM, save the new configuration information in the Configuration/Setup utility program. See “Using the Configuration/Setup Utility main menu” on page 21 for more information.

6. If you replaced a defective DIMM, you must manually enable the DIMM slot in the Configuration/Setup utility program. In this case, the system does not automatically access the Configuration/Setup utility program to enable the DIMM slot. See “Memory settings” on page 31 for additional information.

7. See “Memory board component locations” on page 130 for a layout of the memory board.

External options

Before you begin:

 Read “Safety information” on page 240.  Read the documentation that comes with the

options.

Connecting external SCSI devices: The

server comes with one external SCSI port so that you can connect external SCSI devices.

You can also attach a SCSI storage expansion enclosure to the server.

Cabling requirements:

SCSI devices, you must order additional SCSI cables. These cables must have the proper connectors for the SCSI external connector and the external devices. To select and order the correct cables for use with external devices, contact the IBM reseller or IBM marketing representative.

Refer to the information that comes with the adapter to determine the number of internal and external connectors, channels, and SCSI devices that the adapter supports.

For information about the maximum length of SCSI cable between the terminated ends of the cable, see the following ANSI SCSI Standards:

 X3.131-1986 (SCSI)  X3.131-1994 (SCSI-2)  X3T10/1071D

 X3T10/1142D (Ultra-2 SCSI)  X3.302:1998 (Ultra-2 SCSI)

Adhering to these standards ensures that the server operates properly.

Setting SCSI IDs for external devices:

device that is connected to a SCSI controller must have a unique SCSI ID, so that the SCSI controller can identify the devices and ensure that different devices do not attempt to transfer data at the same time. SCSI devices that are connected to different SCSI controllers can have duplicate SCSI IDs. Refer to “SCSI IDs” on page 112 and to the instructions that come with the SCSI devices for more information about setting a SCSI ID.

port connector

Refer to the illustration in “Input/output connectors and expansion slots” on page 122 for the locations of the connectors.

Serial port:

(Refer to “Input/output connectors and expansion slots” on page 122 for the locations of the connectors.) These ports are used to communicate with printers, plotters, external modems, scanners, and auxiliary terminals. You can also use these ports to transfer data between computers.

Serial ports transfer data one bit at a time, using direct memory access (DMA). DMA is a method of transferring data between I/O devices and system memory without intervention by the system processor.

Serial ports can transfer data means that they can transmit any number of characters at any time, with no restriction on the duration of the pauses between characters.

The serial ports can transmit and receive data and commands at rates of from 300 bits per second up to 345600 bits per second. To use a serial port at 345 600 bits per second, you need a shielded serial cable. For information about this cable, contact your IBM marketing representative or your IBM authorized reseller.

Each serial port has a 9-pin, male D-shell connector on the back of the server. The pin-number assignments of this connector conform to the industry standard.

The server comes with two serial ports.

Hot-swap Power supplies

The server comes with three hot-swap power supplies. The power supplies can provide up to 550 watts each at 110 V AC input power, and 750 watts each at 220 V AC input power.

Danger

Overloading an electrical circuit breaker is potentially a fire hazard and a shock hazard under certain conditions. To avoid these hazards, adhere to the instructions in the following statements.

1. If you are connecting to a 100–127 V AC power source, connect each power cord to a separate branch circuit.

2. If you are connecting to a 200–240 V AC power source and the branch circuit breaker rating is:

a. 13 amps or less, connect each power cord

to a separate branch circuit.

b. 14 amps to 19 amps, do not connect more

than two power cords to the same branch circuit.

c. 20 amps or greater, you may connect up to

three power cords to the same branch circuit.

In addition to the power supplies, the server comes with three 220 V AC power cords, and three 110 V AC power cords (U.S. only). Be sure to select the appropriate power cord voltage for the server environment. All three power cords must have the same voltage.

If you connect the three:

 220 V AC power cords to the power supplies, the

three power supplies support redundancy and hot-swap capability.

 110 V AC power cords to the power supplies, the

three power supplies do not support redundancy if the system configuration exceeds any of these conditions:

– More than six processors – More than 24 memory DIMMs – More than eight PCI adapters

For servers with redundant power, the loss of a single power supply will not affect the server operation. Replace a power supply that has failed as soon as convenient to help maintain the redundant power and cooling capability. When a power supply has failed and the Power Good light is on, the DC power LED on the power supply is off. See “Power supply LED errors” on page 173 for more information on the DC power LEDs. See “Hot-swap power
