  Obtaining Technical Assistance


This section describes the major hardware and software features of your system and provides information about the indicators on the system's front and back panels. It also provides information about other documents you may need when you set up your system and how you can obtain technical assistance.


System Orientation

Figure 1-1 shows the rack and tower versions of your system. The illustrations in this document are based on the rack version.

Figure 1-1. Tower and Rack-Mount Orientations With Standard Bezel


Indicators on the Bezel

The system bezel (standard) incorporates blue and amber system-status indicators. The blue indicator lights up when the system is operating correctly. The amber indicator lights when the system needs attention due to a problem with power supplies, fans, system temperature, or SCSI hard drives.

Table 1-1 lists the system's indicator patterns. Different patterns are displayed that indicate events occurring in the system.

Table 1-1. System-Status Indicator Patterns

Blue Indicator

Amber Indicator

Description

Off

Off

Power is not available to the system.

Off

Blinking

The system has detected an error. See your Installation and Troubleshooting Guide for more information.

On

Off

Power is on, and the system is operational.

Blinking

Off

The indicator has been activated to identify the system in a rack.

NOTE: While the system is being identified, the blue indicator blinks, even though an error has been detected. After the system is identified, the blue indicator stops blinking and the amber indicator resumes blinking.


Front-Panel Features and Indicators

Figure 1-2 shows the controls, indicators, and connectors located on the system's front panel.

Description

Blue system-status indicator

 

The blue system-status indicator lights during normal system operation. Both the systems management software and the identification buttons located on the front and back of the system can cause the blue system-status indicator to flash to identify a particular system.

Amber system-status indicator

 

The amber system-status indicator flashes when the system needs attention due to a problem with power supplies, fans, system temperature, or SCSI hard drives.

NOTE: If the system is connected to AC power and an error has been detected, the amber system status indicator flashes regardless of whether the system has been powered on.

Power button and power-button indicator

The power button controls the DC power supply output to the system.

NOTE: If you turn off the system using the power button and the system is running an ACPI-compliant operating system, the system performs a smooth shutdown before the power is turned off. If the system is not running an ACPI-compliant operating system, the power is turned off immediately after the power button is pressed.

The power-button indicator lights up when power is supplied to the system and the system is operational; it is off when no power is supplied to the system; and it is blinking when the system is in a standby state. For information on standby states, see your operating system documentation.

Power-on indicator

The power-on indicator lights when the system power is on. The power-on indicator blinks when power is available to the system but the system is not powered on.

System identification button

The identification buttons on the front and back panels can be used to locate a particular system within a rack. When one of these buttons is pressed, the blue system status indicator on the front and back blinks until one of the buttons is pressed again.

USB connectors



Connects USB 2.0-compliant devices to the system.

NMI button

Used to troubleshoot software and device driver errors when using certain operating systems. This button can be pressed using the end of a paper clip.

Use this button only if directed to do so by qualified support personnel or by the operating system's documentation.

SCSI Hard-Drive Indicator Codes

Each SCSI hard-drive carrier has two indicators: an activity indicator and a status indicator (see Figure 1-3). The indicators provide information on the status of the hard drive.

NOTE: The drive-activity indicator is not available on systems with optional SATA hard-drives.

Figure 1-3. SCSI Hard-Drive Indicators

Table 1-3 lists the drive indicator codes. Different codes are displayed as drive events occur in the system. For example, if a hard-drive fails, the "drive failed" code appears. After the drive is selected for removal, the "drive being prepared for removal" code appears, followed by the "drive ready for insertion or removal" code. After the replacement drive is installed, the "drive being prepared for operation" code appears, followed by the "drive online" code.

NOTE: If RAID is not activated, only the "drive online" indicator pattern appears. The drive-activity indicator also blinks when the drive is being accessed.

Table 1-3. SCSI Hard-Drive Status Indicator Codes 

Drive-Status Indicator

Back-Panel Features and Indicators

Figure 1-4 shows the controls, indicators, and connectors located on the system's back panel.

Figure 1-4. Back-Panel Features

Connecting External Devices

When connecting external devices to your system, follow these guidelines:

For information about individual connectors, see your Installation and Troubleshooting Guide. For information about enabling, disabling, and configuring I/O ports and connectors, see "Using the System Setup Program."


Power Indicator Codes

The power button on the front panel controls the power input to the system's power supplies. The power indicator can provide information on power status (see Figure 1-2). Table 1-4 lists the power button indicator codes.

Table 1-4. Power Button Indicators

Indicator

Function

On

Indicates that power is supplied to the system and that the system is operational.

Off

Indicates that no power is supplied to the system.

Blinking

Indicates that power is supplied to the system but the system is in a standby state. For information on standby states, see your operating system documentation.

The indicators on the optional redundant power supplies show whether power is present or whether a power fault has occurred (see Figure 1-5).

Table 1-5. Redundant Power-Supply Indicators 

Indicator

Function

Power supply status

Green indicates that the power supply is operational.

Power supply fault

Amber indicates a problem with the power supply.

AC line status

Green indicates that a valid AC source is connected to the power supply.

System Features

NOTE: If you decide to upgrade your system by installing a second processor, you must order the processor upgrade kits from Dell. Not all versions of the Intel Xeon processor work properly as additional processors. The upgrade kit from Dell contains the correct version of the processor, heat sink, and fan as well as the instructions for performing the upgrade. Both processors must have the same internal operating frequency and cache size.
NOTE: Two-way interleaving is not supported in the 256-MB single memory module configuration.
NOTE: The chip fail feature is only supported using x4 memory modules.
NOTE: DVD devices are data only.

The system board includes the following features:

NOTE: Slot 1 accepts half-length PCI cards. Slot 6 accepts full-length unless SCSI is used (because of the SCSI cabling). All other slots accept full-length PCI cards.

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

The following software is included with your system:


Supported Operating Systems


Power Protection Devices

Certain devices protect your system from the effects of problems such as power surges and power failures.


Other Documents You May Need

CAUTION: The Product Information Guide provides important safety and regulatory information. Warranty information may be included within this document or as a separate document.
NOTE: Always read the updates first because they often supersede information in other documents.
