The basic troubleshooting procedures can help you diagnose a system problem. These procedures can often reveal the source of a problem or indicate the correct starting point for servicing the system. See your Installation and Troubleshooting Guide for more detailed instructions for troubleshooting your system.

A brief explanation of how to load and start the system diagnostics can be found in "Running the System Diagnostics."

Perform the following procedures in the order presented.

Initial User Contact

When you first contact a user who has a problem, ask the user to describe the problem and the conditions under which it occurs. After the user describes the problem, perform the following steps:

1. Ask the user to back up any data on the hard drive if the system's condition permits. See the documentation provided with the operating system or applications software for information about backing up data.

2. Ask the user to try to duplicate the problem by repeating the operations he or she was performing at the time the problem occurred.

Can the user duplicate the problem?

Yes. Proceed to step 3.

No. Proceed to the next section, "External Visual Inspection."

3. Observe the user to determine if he or she is making an error, such as typing an incorrect key combination or entering a command incorrectly.

Is the problem a result of user error?

Yes. Instruct the user in the proper procedure or direct the user to the appropriate user documentation for the correct procedure.

No. Proceed to "External Visual Inspection."

External Visual Inspection

Improperly set switches and controls and loose or improperly connected cables are the most likely source of problems for the system, monitor, or other peripherals (such as a keyboard, mouse, or other external equipment). A quick check of all the switches, controls, and cable connections can easily solve these problems.

The external visual inspection consists of a quick inspection of the exterior of the system, the monitor, (if attached), the keyboard (if attached), any peripherals, and cables. While performing the visual inspection, make any necessary corrections.

To perform the external visual inspection, perform the following steps:

1. Inspect the status indicators that can signify component malfunction.

2. Turn off the system, the monitor (if attached), and all peripherals.

3. Verify that all power cables are properly connected to the system, the monitor and peripherals, and their power sources.

4. Inspect connections to any attached devices including network cables, keyboard, monitor, mouse (if used), or keyboard/video/mouse (KVM) switch (if used), as well as any devices attached to the serial port.

5. Inspect all external monitor controls for any obvious damage or improper settings (if used). For proper settings of the video monitor controls, see the documentation for the monitor.

6. Inspect the keyboard (if used) to ensure that no keys are sticking. If keys are sticking, it may be necessary to replace the keyboard.

7. Inspect the exterior of the system, including all controls and indicators, and all user- accessible data storage devices for any signs of physical damage.

Does the inspection reveal any problems?

Yes. Proceed to the appropriate procedure in "Removing and Replacing Parts."

No. Proceed to "Observing the Boot Routine."

Observing the Boot Routine

After you have performed an external visual inspection, boot the system and, while the boot routine is running, observe the system for any indications of problems.

To observe problem indications during the boot routine, perform the following steps:

1. If the system is off, turn on all peripherals and the system.

During the POST, the following message appears:

<F10> = Utility Mode

2. Press <F10> to access the utility mode.

The utility partition provides a text-based interface from which you can run the partition's utilities. To select a menu option, you can either use the arrow keys to highlight the option and press <Enter>, or type the number of the menu option. To exit the utility partition, press <Esc> from the Main Menu. Exiting the utility from the setup mode causes the system to reboot to the standard operating-system boot partition.

3. Check the power-supply indicators.

Is the red fault indicator lit?

Yes. Troubleshoot the system power supply (see your Installation and Troubleshooting Guide).

No. Proceed to step 4.

4. Watch the <Num Lock>, <Caps Lock>, and <Scroll Lock> indicators on the upper-right corner of the keyboard. After all three indicators flash momentarily, and following a long pause (approximately 30 seconds), the <Num Lock> indicator should light up and remain on (unless the Num Lock option is set to off in the System Setup Program).

Do these indicators flash on and off within approximately 10 seconds after the boot routine starts?

Yes. Proceed to step 5.

No. Replace the keyboard with a known working keyboard. If the problem persist, troubleshoot the system power supply. If the troubleshooting

procedure indicates that the system power supply is operational, troubleshoot the memory.

5. During the boot routine, observe the system for any of the following indications:

l Beep codes — A beep code is a series of beeps that indicates an error condition. See "System Beep Codes." l System error messages — These messages can indicate problems or provide status information. If a system error message appears, see "System

Messages."

l Diskette-drive and hard drive access indicators — These indicators light up in response to data being transferred to or from the drives. If either if

these indicators fails to light up during the boot routine, troubleshoot the diskette drive or hard drive subsystem, as appropriate.

6. From the utility partition's main menu, select the Run System Diagnostics option from Run System Utilities and observe the monitor screen for the Diagnostics menu.

Does the Diagnostics menu appear?

Yes. See "Running the System Diagnostics."

No. Proceed to step 7.

7. Insert a copy of the diagnostics diskette into the diskette drive, and reboot the system.

Solving Problems Described by LCD Status Messages

When a single message appears on the status LCD, locate the code in Table3-9 and perform the suggested corrective action. The code on the LCD can often specify a very precise fault condition that is easily corrected. For example, if the code E0280MISSINGVRM2 appears, you know that a microprocessor is installed in socket 2, but the VRM for that microprocessor is either improperly installed or missing.

In contrast, you might be able to determine the problem if multiple related errors occur. For example, if you receive a series of messages indicating multiple voltage faults, you might determine that the problem is a failing power supply.

Removing LCD Status Messages

For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed when that sensor returns to a normal state. For example, if temperature for a component goes out of range, the LCD displays the fault; when the temperature returns to the acceptable range, the message is removed from the LCD. For other faults, you must take action to remove the message from the display:

l Clear the SEL — You can perform this task remotely, but you will lose the event history for the system. l Chassis intrusion — When you remove the cover, the system assumes that you are servicing the bad component; the LCD clears when you replace the

cover.

l Power cycle — Turn off the system and disconnect it from the electrical outlet; wait approximately ten seconds, reconnect the power cable, and restart

the system.

Any of these actions will remove fault messages, and return the status indicators and LCD colors to the normal state. Messages will reappear under the following conditions:

l The sensor returns to a normal state but fails again, resulting in a new SEL entry. l The system is reset and new error events are detected. l A failure is recorded from another source that maps to the same display entry.

System Messages

System messages appear on the console during POST to notify you of a possible problem with the system. If you are performing console redirection, system messages will appear on the remote console. Table3-10 lists the system messages that can occur and the probable cause for each message.

System Overview

Dell™PowerEdge™2650SystemsServiceManual

System Features Supported Operating Systems Service Features Power Protection Devices Other Documents You May Need Technical Specifications

Your system is a high-speed, full-featured server that offers significant service and upgrade features. This section describes the major features of the system, including those that simplify servicing. It also provides information about other documents you may need when setting up your system.

The hard drive that boots your operating system has a utility partition containing complete diagnostics for your system. Also, a separate CD is provided that includes diagnostics software that you can download to a set of diskettes.

System Features

l One or two Intel®Xeon™microprocessorswithaninternaloperatingspeedofatleast1.8GHz,a512KBcache,andafront-side (external) bus speed

of 400 MHz.

The microprocessors in your system provide NetBurst microarchitecture and Hyper-Threading Technology to significantly increase microprocessor performance. Hyper-Threading allows one physical microprocessor to appear as two logical processors to the operating system and application programs. Hyper-Threading also allows each microprocessor to simultaneously execute multiple tasks using shared hardware resources.

These new technology features in the microprocessor provide the following for multithreaded tasks:

¡ Enhanced system performance ¡ Improved reaction and response time for the system ¡ Increased number of users that a system can support ¡ Increased number of transactions that can be executed simultaneously by the system

You can find more information about Hyper-Threading at developer.intel.com.

l SMP, which is available on systems with two Xeon microprocessors. SMP greatly improves overall system performance by dividing microprocessor

operations between independent microprocessors. To take advantage of this feature, you must use an operating system that supports multiprocessing.

l A minimum of 256 MB of system memory, upgradable to a maximum of 6 GB by installing identical pairs of DDR SDRAM memory modules in the six memory

module sockets on the system board.

l Support for up to five 1-inch, internal Ultra3 SCSI hard drives (with hot-plug capacity when using the optional ROMB card). l A single, 1.44-MB, 3.5-inch diskette drive. l An IDE CD or DVD drive. l Up to two hot-pluggable, 500-W AC or DC power supplies in a 1 + 1 redundant configuration. l Hot-pluggable system cooling fans and two additional fans integrated in the power supplies. l An intrusion switch that signals the appropriate systems management software if the bezel is removed.

System Board Features

l Three 64-bit PCI/PCI-X slots located on the riser card (two slots on bus 1 and one slot on bus 2). Slots accept full-length cards designed for PCI-X up to

133 MHz.

l An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8 MB of SDRAM video memory

(nonupgradable). Maximum resolution is 1600 x 1200 x 16.7 million colors (noninterlaced).

l An integrated, dual-channel Ultra3 SCSI host adapter. The internal channel supports up to five SCSI hard drives on a 1 x 5 or 2/3 split SCSI backplane

and provides internal RAID support. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination on individual hard drives, greatly simplifying drive installation.

l Memory spare bank feature, which provides your system with failover to a previously reserved row of memory if one row of memory fails. l Optional ROMB through an integrated subsystem that incorporates a 128 MB cache memory module, a RAID battery, and a RAID key. l Two integrated 10/100/1000 NICs, which provide an Ethernet interface. l Embedded systems management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The systems

management circuitry works in conjunction with your systems management software.

NOTE: If you decide to upgrade your system by installing an additional microprocessor, you must order the microprocessor upgrade kits from the

company where you purchased your system. Not all versions of the Intel Xeon MP microprocessor will work properly as additional microprocessors. The upgrade kit contains the correct version of the microprocessor as well as the instructions for performing the upgrade. All microprocessors must have the same internal operating frequency and cache size.

l Back-panel connectors including video, keyboard, mouse, two serial, two USB, embedded remote access Ethernet, and two NICs. l Front-panel connectors including video, keyboard, mouse, and USB.

For more information about specific features, see "Technical Specifications."

Software Features

The following software is included with your system:

l A System Setup program for quickly viewing and changing system configuration information. For more information on this program, see "Using the

System Setup Program."

l Enhanced security features, including a system password and a setup password, available through the System Setup program. l System diagnostics for evaluating system components and devices. For information on using the system diagnostics, see "Running the System

Diagnostics."

l Video drivers for displaying many application programs in high-resolution modes. For more information on drivers, see "Using the Dell OpenManage

Server Assistant CD" in your User's Guide.

l SCSI device drivers that allow the operating system to communicate with devices attached to the integrated SCSI subsystem. For more information on

drivers, see "Installing and Configuring SCSI Drivers" in your User's Guide.

l Systems management software and documentation. l Optional solutions software for web hosting, caching, or load balancing. See your solutions software documentation for more information.

Supported Operating Systems

l Microsoft®Windows®2000 Server and Advanced Server l Windows NT®4.0 Server, Enterprise Edition l Red Hat Linux 7.x, or later

Service Features

The system includes the following service features to make troubleshooting and repair easy and effective, in most cases without tools or service aids:

l System diagnostics are available on the utility partition, which checks for hardware problems (if the system can boot). The diagnostics can also be

installed onto diskettes from the Dell OpenManage Server Assistant CD.

l Optional systems management hardware and software, which monitors temperatures and voltages throughout the system and notifies you if the

system overheats, if a system cooling fan malfunctions, if a microprocessor overheats, or if a power supply or VRM fails. For information about the systems management option, see your systems management software documentation.

l The system simplifies removing and replacing components. You can replace microprocessors or memory modules without removing the system board.

The SCSI backplane board and hard-drive carriers eliminate the extensive cabling and drive configuration usually required for a SCSI subsystem.

Power Protection Devices

A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The following subsections describe some of these devices.

Surge Protectors

Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.

Line Conditioners

Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's AC power source voltage at a fairly constant level and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectors—up to several hundred dollars. However, these devices cannot protect against a complete loss of power.

Uninterruptible Power Supplies

UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when AC power is unavailable or unusable. The battery is charged by the AC power while it is available so that once AC power is lost, the battery can provide power to the system for a limited amount of time—from 15 minutes to an hour or so—depending on the UPS system.

UPS systems that provide only 5 minutes of battery power allow you to conduct shutdown of the system but are not intended to provide continued operation. Use surge protectors with all UPS systems, and ensure that the UPS systems are UL safety approved.
