  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 setting up your system and how to 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

Indicators on the Bezel

The locking system bezel (optional on rack configurations) incorporates a system status indicator. The system status indicator lights blue when the system is operating correctly and lights amber 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.

Table 1-1. System Status Indicator Patterns

Front-Panel Features and Indicators

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

SCSI Hard-Drive Indicator Codes

If RAID is activated, two indicators on each of the hard-drive carriers provide information on the status of the SCSI hard drives. RAID can be enabled either by using ROMB on the expansion-card cage or by using a RAID card connected to the backplane. 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 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. Hard-Drive Indicator Patterns 

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 and Indicators

Connecting External Devices

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

• Most devices must be connected to a specific connector and device drivers must be installed before the device operates properly. (Device drivers are normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific installation and configuration instructions.
  
  
• Always attach external devices while your system is turned off. Next, turn on any external devices before turning on the system (unless the documentation for the device specifies otherwise).
  
  

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

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

NOTE: The power supply fans operate when a valid AC source is connected to the power supply even though the system is may not be powered on.

System Features

• One or two Intel® Xeon™ processors with an internal operating speed of at least 2.8 GHz, internal cache of at least 1 MB, and a front-side bus operating at 800 MHz.
  
  
• Support for symmetric multiprocessing (SMP), which is available on systems with two Intel Xeon processors. SMP greatly improves overall system performance by dividing processor operations between independent processors. To take advantage of this feature, you must use an operating system that supports multiprocessing.
  
  

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 will 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.

• A minimum of 256 MB of registered PC2-3200 DDR 2 400 SDRAM memory modules, upgradable to a maximum of 16 GB by installing combinations of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB (when available) 2-way interleaving memory modules in the six memory module sockets on the system board.
  
  

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.

The system also features redundant memory, which provides a failover memory bank or memory mirroring. The failover memory bank (spare bank) is available if all banks (six memory modules) are populated with identical memory modules. The memory mirroring feature is available only if banks 1 and 2 (four memory modules) are populated with identical memory modules.

• Support for up to ten 1-inch, internal hot-pluggable U320 SCSI hard drives (eight 1-inch drives using a 1x8 SCSI backplane board, and support for two 1-inch drives in the peripheral bay using an optional 1x2 SCSI backplane board). An optional daughter card provides support for a 2x4 split backplane.
  
  
• Peripheral bay provides support for an optional half-height tape backup unit and two 1-inch SCSI hard drives or a full-height tape backup unit
  
  
• An optional single, 1.44-MB, 3.5-inch diskette drive.
  
  
• An optional IDE CD, DVD, or combination CD-RW/DVD drive.

PCI slot 1 is a 5-V, 32-bit, 33-MHz slot; slots 2 through 5 are 3.3-V, 64-bit, 133-MHz PCI-X slots; slot 6 is a hot-pluggable 3.3-V, PCIe x4 lane slot; and slot 7 is a hot-pluggable 3.3-V, PCIe x8 lane slot. Expansion-card slots accommodate full-height, full-length expansion cards.
  
  
• An integrated, dual-channel U320 SCSI host adapter. The internal channel supports up to ten SCSI hard drives using the 1x8 and 1x2 SCSI backplanes. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination, greatly simplifying drive installation.
  
  
• Optional ROMB activated by using a ROMB key, a 256-MB DDR2 400 memory module, and a RAID battery.
  
  
• Optional RAID through a separate controller card that incorporates 128 MB of cache memory and a RAID battery.
  
  
• Two integrated Gigabit Ethernet NICs, capable of supporting 10-Mbps, 100-Mbps, and 1000-Mbps data rates.
  
  
• Four USB 2.0-compliant connectors (two on the front and two on the back) capable of supporting a diskette drive, a CD-ROM drive, a keyboard, a mouse, or a USB flash drive.
  
  
• Optional remote access controller (RAC) for remote systems management.
  
  
• An integrated VGA-compatible video subsystem with an ATI Radeon 7000-M, 33-MHz PCI video controller. This video subsystem contains 16 MB of SDRAM video memory (nonupgradable).

Power Protection Devices

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

• PDU — Uses circuit breakers to ensure that the AC current load does not exceed the PDU's rating.
  
  
• Surge protector — Prevents voltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. They do not protect against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
  
  
• Line conditioner — Maintains a system's AC power source voltage at a moderately constant level and provides protection from brownouts, but does not protect against a complete power loss.
  
  
• UPS — Uses battery power to keep the system running when AC power is unavailable. The battery is charged by AC power while it is available so that after AC power is lost, the battery can provide power to the system for a limited amount of time—from 5 minutes to approximately an hour. A UPS that provides only 5 minutes of battery power allows you to save your files and to shut down the system. Use surge protectors and PDUs with all universal power supplies, and ensure that the UPS is UL-safety approved.
