  Obtaining Technical Assistance


Your system is a rack-dense, full-featured, highly available, rack-mount system equipped with one or two Intel® Xeon™ microprocessors.

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 setting up your system and how to obtain technical assistance.


Indicators on the Optional Bezel

The optional system bezel incorporates a system status indicator divided into blue and amber system status indicators. See Figure 1-1. The blue indicator lights up when the system is operating correctly. The amber indicator lights up when the system needs attention due to a problem with power supplies, fans, system temperature, or hard drives.

Table 1-1 lists the system's indicator patterns. Different patterns are displayed as events occur in the system.

Figure 1-1. System Status Indicators

Table 1-1. System Status Indicator Patterns

Blue indicator

Amber indicator

Description

Off

Off

Power is not available to the system, or power is available to the system, but the system is not powered on. See your Installation and Troubleshooting Guide for more information.

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 behind the optional bezel on the system's front panel.

Description

blue system status indicator

The blue system status indicator lights up 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 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.

NIC1 and NIC2 link and activity indicators


The link and activity indicators for the two integrated NICs light intermittently when the NICs are in use.

hard-drive indicator

The green hard-drive activity indicator flashes when the hard drives are in use. See Figure 1-3 for more information on hard-drive indicators.

power-on indicator, power button

The power-on indicator lights when the system power is on.

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 graceful 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.

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 pushed, the blue system status indicator on the front and back blinks until one of the buttons is pushed again.

USB connector

Connects a USB 1.1-compliant device to the system.

video connector

Connects a monitor to the system.

SCSI Hard-Drive Indicator Codes

If the optional RAID on motherboard (ROMB) card is activated, two indicators on each of the hard-drive carriers provide information on the status of the SCSI hard drives. See Figure 1-3 and Table 1-3. The SCSI backplane firmware controls the drive power-on/fault indicator.

Figure 1-3. SCSI Hard-Drive Indicators

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

NOTE: If the optional ROMB card is not installed, only the "drive online" indicator pattern appears. The drive-activity indicator also blinks when the drive is being accessed.

Table 1-3. Hard-Drive Indicator Patterns 

Condition

Indicator Pattern

Identify drive

The green power-on/fault indicator blinks four times per second.

Drive being prepared for removal

The green power-on/fault indicator blinks two times per second.

Drive ready for insertion or removal

Both drive indicators are off.

Drive being prepared for operation

The green power-on/fault indicator is on.

Drive predicted failure

The power-on/fault indicator slowly blinks green, amber, and off.

Drive failed

The amber power-on/fault indicator blinks four times per second.

Drive rebuilding

The green power-on/fault indicator blinks slowly.

Drive online

The green power-on/fault indicator is on.


Back-Panel Features and Indicators

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

NOTE: Connect the power cable to connector PS1 if your system only has one power supply. See Figure 1-4.

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."


System Features

NOTE: If you decide to upgrade your system by installing a second microprocessor, you must order the microprocessor upgrade kits from Dell. Not all versions of the Intel Xeon microprocessor will work properly as additional microprocessors. The upgrade kit from Dell contains the correct version of the microprocessor as well as the instructions for performing the upgrade. Both microprocessors must have the same internal operating frequency and cache size.

The system board includes the following features:

or

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

The System 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.

Obtaining Technical Assistance

If you do not understand a procedure in this guide or if the system does not perform as expected, see your Installation and Troubleshooting Guide.
