Guidelines for trained service technicians

This section contains information for trained service technicians.

Inspecting for unsafe conditions

Use the information in this section to help you identify potential unsafe conditions in an IBM product that you are working on. Each IBM product, as it was designed and manufactured, has required safety items to protect users and service technicians from injury. The information in this section addresses only those items. Use good judgment to identify potential unsafe conditions that might be caused by non-IBM alterations or attachment of non-IBM features or options that are not addressed in this section. If you identify an unsafe condition, you must determine how serious the hazard is and whether you must correct the problem before you work on the product.

Consider the following conditions and the safety hazards that they present:

v Electrical hazards, especially primary power. Primary voltage on the frame can

cause serious or fatal electrical shock.

v Explosive hazards, such as a damaged CRT face or a bulging capacitor.

v Mechanical hazards, such as loose or missing hardware.

inspect the product for potential unsafe conditions, complete the following steps:

1. Make sure that the power is off and the power cord is disconnected.

2. Make sure that the exterior cover is not damaged, loose, or broken, and observe any sharp edges.

3. Check the power cord:

v Make sure that the third-wire ground connector is in good condition. Use a

meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.

v Make sure that the power cord is the correct type, as specified in “Power

cords” on page 26.

v Make sure that the insulation is not frayed or worn.

Remove the cover.

5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6. Check inside the server for any obvious unsafe conditions, such as metal filings, contamination, water or other liquid, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Make sure that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Guidelines for servicing electrical equipment

Observe the following guidelines when servicing electrical equipment:

v Check the area for electrical hazards such as moist floors, nongrounded power

extension cords, power surges, and missing safety grounds.

v Use only approved tools and test equipment. Some hand tools have handles that

are covered with a soft material that does not provide insulation from live electrical currents.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition. Do not use worn or broken tools or testers.

viii IBM System x3850 Type 8864: Problem Determination and Service Guide

v Do not touch the reflective surface of a dental mirror to a live electrical circuit.

The surface is conductive and can cause personal injury or equipment damage if it touches a live electrical circuit.

v Some rubber floor mats contain small conductive fibers to decrease electrostatic

discharge. Do not use this type of mat to protect yourself from electrical shock.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical

outlet so that you can turn off the power quickly in the event of an electrical accident.

v Disconnect all power before you perform a mechanical inspection, work near

power supplies, or remove or install main units.

v Before you work on the equipment, disconnect the power cord. If you cannot

disconnect the power cord, have the customer power-off the wall box that supplies power to the equipment and lock the wall box in the off position.

v Never assume that power has been disconnected from a circuit. Check it to

make sure that it has been disconnected.

v If you have to work on equipment that has exposed electrical circuits, observe

the following precautions:

– Make sure that another person who is familiar with the power-off controls is

near you and is available to turn off the power if necessary.

– When you are working with powered-on electrical equipment, use only one

hand. Keep the other hand in your pocket or behind your back to avoid creating a complete circuit that could cause an electrical shock.

– When using a tester, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on a suitable rubber mat to insulate you from grounds such as metal

floor strips and equipment frames.

Use extreme care when measuring high voltages.

v To ensure proper grounding of components such as power supplies, pumps,

blowers, fans, and motor generators, do not service these components outside of their normal operating locations.

v If an electrical accident occurs, use caution, turn off the power, and send another

person to get medical aid.

Attention: If you set an administrator password and then forget it, there is no way

to change, override, or remove it. You must replace the I/O board.

Installing and using the baseboard management controller utility programs

The baseboard management controller provides environmental monitoring for the server. If environmental conditions exceed thresholds or if system components fail, the baseboard management controller lights LEDs to help you diagnose the problem and also records the error in the System Event/Error log.

Also use the baseboard management controller to establish a Serial over LAN (SOL) connection to manage servers from a remote location. You can remotely view

Chapter 2. Configuration information and instructions 19

and change the BIOS settings, restart the server, identify the server, and perform other management functions. Any standard Telenet client application can access the SOL connection.

Note: The server Ethernet ports are set to DHCP by default. The BMC MAC

address can be found on a tag on the front of the server. Once you have deployed the server, remove the BMC MAC address tag so that it does not impede airflow through the front of the server.

Use the baseboard management controller firmware update utility program to download a baseboard management controller firmware update. The firmware update utility program updates the baseboard management controller firmware and does not affect any device drivers.

Go to http://www.ibm.com/servers/eserver/support/xseries/index.html to download the utility program; then, copy the Flash.exe file to a firmware update diskette.

Note: To ensure proper server operation, be sure to update the server baseboard

management controller firmware before updating the BIOS code.

Utility appears, press Ctrl+A. If an administrator password has been set, you

are prompted to type the password.

3. Follow the instructions on the screen to configure the controller settings.

to http://www.ibm.com/servers/eserver/support/xseries/index.html to check for

Go the latest version of the SAS firmware.

Configuring the Ethernet controller

The Ethernet controller is integrated on the system board. It provides an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in the server support auto-negotiation, the controller detects the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operates at that rate and mode.

You do not have to set any jumpers or configure the controller. However, you must install a device driver to enable the operating system to address the controller. For device drivers and information about configuring the Ethernet controller, see the

Broadcom NetXtreme Gigabit Ethernet Software CD that comes with the server. For

updated information about configuring the controller, go to http://www.ibm.com/ servers/eserver/support/xseries/index.html.

Using the PXE boot agent utility program

The Preboot Execution Environment (PXE) boot agent utility program is part of the BIOS code. You can use it to specify the startup order of devices and enable or disable operating-system wake-up support.

20 IBM System x3850 Type 8864: Problem Determination and Service Guide

Note: The server does not support changing the network boot protocol or

specifying the startup order of devices through the PXE boot agent utility program.

Chapter 4. Removing and replacing server components

Replaceable components are of three types:

v Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your

responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for the installation.

v Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or

request IBM to install it, at no additional charge, under the type of warranty service that is designated for your server.

v Field replaceable unit (FRU): FRUs must be installed only by trained service

technicians.

Chapter 3, “Parts listing, Type 8864,” on page 23 to determine whether a

See component is a Tier 1 CRU, Tier 2 CRU, or FRU.

For information about the terms of the warranty and getting service and assistance, see the Warranty and Support Information document.

Installation guidelines

Before you install options, read the following information:

v Read the safety information that begins on page vii, the guidelines in “Working

inside the server with the power on” on page 30, and “Handling static-sensitive devices” on page 31. This information will help you work safely.

v When you install your new server, take the opportunity to download and apply

the most recent firmware updates. This step will help to ensure that any known issues are addressed and that your server is ready to function at maximum levels of performance. To download firmware updates for your server, go to http://www.ibm.com/servers/eserver/support/xseries/index.html, select System x3850 from the Hardware list, click Go, and then click the Download tab. For additional information about tools for updating, managing, and deploying firmware, see the System x and xSeries Tools Center at http:// publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.

v Before you install optional hardware devices, make sure that the server is

working correctly. Start the server, and make sure that the operating system starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly. If the server is not working correctly, see Chapter 5, “Diagnostics,” on page 63 for diagnostic information.

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v If you must start the server while the cover is removed, make sure that no one is

near the server and that no tools or other objects have been left inside the server.

v Do not attempt to lift an object that you think is too heavy for you. If you have to

lift a heavy object, observe the following precautions:

– Make sure that you can stand safely without slipping.

– Distribute the weight of the object equally between your feet.

– Use a slow lifting force. Never move suddenly or twist when you lift a heavy

object.

– To avoid straining the muscles in your back, lift by standing or by pushing up

with your leg muscles.

Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

v Back up all important data before you make changes to disk drives.

v Have a small flat-blade screwdriver available.

v You do not have to turn off the server to install or replace hot-swap power

supplies, hot-swap fans, hot-plug adapters, or hot-plug Universal Serial Bus (USB) devices. However, you must turn off the server before you perform any steps that involve removing or installing adapter cables.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

v When you are finished working on the server, reinstall all safety shields, guards,

labels, and ground wires.

v For a list of supported optional devices for the server, see http://www.ibm.com/

servers/eserver/serverproven/compat/us/.

System reliability guidelines

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

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed in it.

v If the server has redundant power, each of the power-supply bays has a power

supply installed in it.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the server cover before turning on the server. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components.

v You have followed the cabling instructions that come with optional adapters.

v You have replaced a failed fan as soon as possible.

v You have replaced a hot-swap drive within 2 minutes of removal.

v You do not remove the air baffle while the server is running. Operating the server

without the air baffle might cause the microprocessor to overheat.

v Microprocessor socket 2 always contains either a microprocessor baffle or a

microprocessor and heat sink.

Working inside the server with the power on

Attention: Static electricity that is released to internal server components when

the server is powered-on might cause the server to halt, which could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

30 IBM System x3850 Type 8864: Problem Determination and Service Guide

The server supports hot-plug, hot-add, and hot-swap devices and is designed to operate safely while it is turned on and the cover is removed. Follow these guidelines when you work inside a server that is turned on:

v Avoid wearing 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, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that could fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Handling static-sensitive devices

Attention: Static electricity can damage the server and other electronic devices.

To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

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

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

you.

v The use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

v Handle the device carefully, holding it by its edges or its frame.

v Do not touch solder joints, pins, or exposed circuitry.

v Do not leave the device where others can handle and damage it.

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

metal part on the outside of the server for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

indoor humidity and increases static electricity.

Returning a device or component

If you are instructed to return a device or component, follow the packaging instructions provided with the replacement part. Use any packaging materials for shipping that are supplied to you.

Removing the cover and bezel

To remove the cover and bezel, complete the following steps:

1. Read the safety information that begins on page vii, and “Handling static-sensitive devices.”

v There are two memory power buses split between the four memory cards.

Memory cards 1 and 2 are on power bus 1, and memory cards 3 and 4 are on power bus 2. If memory mirroring is enabled, you can hot-replace one memory card at a time on each memory power bus.

v If a problem with a DIMM is detected, light path diagnostics will light the

system-error LED on the front of the server, indicating that there is a problem and guide you to the defective DIMM. When this occurs, first identify the defective DIMM; then, remove and replace the DIMM.

The following illustration shows the LEDs on the memory card:

Memory Hot-Swap Enabled LED: When this LED is lit, it indicates that

hot-swap memory is enabled.

Error LED: When this LED is lit, it indicates that a memory card or DIMM has

failed.

Memory Port Power LED: When this LED is off, it indicates that power is

removed from the port and that you can remove the memory card and replace a failed DIMM. This LED will also turn off when the release levers are opened.

Active Memory

Active Memory is an IBM technology that improves the reliability of the DIMMs through memory mirroring, memory scrubbing, and Memory ProteXion™ features.

The following notes describe the Active Memory features:

v Memory mirroring enables you to improve the reliability of the memory in your

server by creating a mirror of the data in memory port 1 and storing it in memory port 2.

Note: For memory mirroring to work, you must have DIMMs of the same size

and clock speed in both memory ports.

Complete the following steps to enable memory mirroring:

1. Check your operating system documentation to make sure that it supports memory mirroring.

2. Install DIMMs of the same size and clock speed in the two memory ports.

3. Enable memory mirroring in the Configuration/Setup Utility program:

a. Turn on the server and watch the monitor screen. b. When the message Press F1 for Configuration/Setup appears, press

F1.

c. From the Configuration/Setup Utility main menu, select Advanced Setup. d. Select Memory Settings. e. Select Memory Mirroring Settings. f. Enable the memory mirroring setting from within this window.

g. Save and exit the Configuration/Setup Utility program.

When memory mirroring is enabled, the data that is written to memory is stored in two locations. One copy is kept in the memory port 1 DIMMs, while a second copy is kept in the memory port 2 DIMMs. During the execution of the read command, the data is read from the DIMM with the least number of reported memory errors through Memory scrubbing, which is enabled with memory mirroring.

If memory scrubbing determines that a DIMM is damaged beyond use, read and write operations are redirected to the remaining good DIMMs. Memory scrubbing then reports the damaged DIMM and the Light Path Diagnostics feature displays the error. After the damaged DIMM is replaced, memory mirroring then copies the mirrored data back into the new DIMM.

v Memory scrubbing is an automatic daily test of all the system memory that

detects and reports memory errors that might be developing before they cause a server outage.

Note: Memory scrubbing and Memory ProteXion technology work with each

other and do not require memory mirroring to be enabled to work.

When an error is detected, memory scrubbing determines whether the error is recoverable. If it is recoverable, Memory ProteXion is enabled and the data that was stored in the damaged locations is rewritten to a new location. The error is then reported so that preventive maintenance can be performed. Provided that there are enough good locations to enable the correct operation of the server, no further action is taken other than recording the error in the error logs.

If the error is not recoverable, memory scrubbing sends an error message to the Light Path Diagnostics feature, which then lights the applicable LEDs to guide you to the damaged DIMM. If memory mirroring is enabled, the mirrored copy of the data in the mirrored DIMM is used to refresh the new DIMM after it is installed.

40 IBM System x3850 Type 8864: Problem Determination and Service Guide

v Memory ProteXion reassigns memory bits to new locations within memory when

recoverable errors have been detected.

When a recoverable error is found by memory scrubbing, the Memory ProteXion feature writes the data that was to be stored in the damaged memory locations to spare memory locations within the same DIMM.

Chapter 5. Diagnostics

This chapter provides basic troubleshooting information to help you solve some common problems that might occur with the server.

If you cannot locate and correct the problem using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 161 for more information.

Diagnostic tools

The following tools are available to help you diagnose and solve 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” for more information.

v Problem isolation tables

Use these tables to help you diagnose various symptoms. See “Problem isolation tables” on page 88.

v Light path diagnostics

Use the light path diagnostics to diagnose system errors quickly. See “Light path diagnostics” on page 101 for more information.

v Diagnostic programs and error messages

The diagnostic programs are stored in memory on the microprocessor tray. These programs are the primary method of testing the major components of the server. See “Diagnostic programs, messages, and error codes” on page 110 for more information.

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 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, and the first screen of the operating system opens, or an application program starts.

If POST detects a problem, more than one beep might sound, or an error message appears on the screen. See “Beep code descriptions” on page 64 and “POST error codes” on page 72 for more information.

Notes:

1. If a power-on password is 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, correct the cause of the first error message. The other error messages usually will not occur the next time you run the test.

POST beep codes

A beep code is a combination of short or long beeps or a series of short beeps separated by pauses. For example, a “1-2-3” beep code is one beep, a pause, two beeps, a pause, and three beeps.

When POST is completed, one beep is emitted to indicate that the server is working correctly. If POST detects a problem during startup, other beep codes might occur. See “Beep code descriptions” to help diagnose and solve problems that are detected during startup. If no beep code sounds, see “No-beep symptoms” on page

69.

Beep code descriptions

The following table describes the beep codes and suggested actions to correct the detected problems.

Error logs

The POST error log contains the three most recent error codes and messages that were generated during POST. The BMC log and the system-error log contain messages that were generated during POST and all system status messages from the service processor.

70 IBM System x3850 Type 8864: Problem Determination and Service Guide

Notes:

v The BMC log is limited in size and is designed so that when the log is full, new

entries will not overwrite existing entries; therefore, you must periodically clear the BMC log from the Configuration/Setup Utility program (the menu choices are described in the User’s Guide).

v When troubleshooting an error, make sure to clear the BMC log so that you can

find current errors more easily.

v Entries written to the BMC log early in the POST procedure will show an

incorrect date as the default timestamp; however, the date and time will correct itself as POST continues.

v Each BMC log entry appears on its own page; to display all the data for an entry,

use the up arrow (—) and down arrow (–) or the Page Up and Page Down keys. To move from one entry to the next, move the cursor to the Get Next Entry or

Get Previous Entry line; then, press Enter.

v The log indicates an Assertion Event when an event has occurred. It indicates a

Deassertion Event when the event is no longer occurring.

v Some of the error codes and messages in the BMC log are abbreviated.

v Viewing the BMC log through the web interface of the optional Remote

Supervisor Adapter II SlimLine allows all messages to be translated.
