or
¡ A riser card (when available) that has one x4 lane width and one x8 lane width, PCI-Express expansion slots and ROMB. Expansion card slots
accommodate half-length expansion cards.
l An integrated, single-channel U320 SCSI host adapter. The internal channel supports up to two SCSI hard drives on the SCSI backplane. The SCSI
backplane automatically configures SCSI ID numbers and SCSI termination, greatly simplifying drive installation.
l Optional RAID through a separate controller card that incorporates 256 MB of cache memory and a RAID battery.
l Two integrated Gigabit Ethernet NICs, capable of supporting 10-Mbps, 100-Mbps, and 1000-Mbps data rates.
l 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.
l Optional remote access controller (RAC) for remote systems management.
l An integrated VGA-compatible video subsystem with an ATI Radeon 7000-M, 33MHz PCI video controller. This video subsystem contains 16MB of SDRAM
video memory (nonupgradable). Maximum resolution is 1600 x 1200 with 64,000 colors; true-color graphics are supported in the following resolutions:
640 x 480, 800 x 600, 1024 x 768, 1152 x 864, and 1280 x 1024. When the optional remote access card is installed, the video resolution is 1024 X 768.
l 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 the systems management software.
l Back-panel connectors include mouse, keyboard, serial, video, two USB connectors, and two NIC connectors.
l Front-panel connectors include a video and two USB connectors.
For more information about specific features, see " Technical Specifications ."
The following software is included with your system:
l A System Setup program for quickly viewing and changing system configuration information. For more information about 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 about using the system diagnostics, see "Running the System
Diagnostics" in your Installation and Troubleshooting Guide.
l Video drivers for displaying many popular application programs in high-resolution modes.
l SCSI device drivers that allow the operating system to communicate with devices attached to the integrated SCSI subsystem. For more information
about these drivers, see "Installing Drives" in your Installation and Troubleshooting Guide.
l Systems management software and documentation CDs.

Power Protection Devices
Certain devices protect your system from the effects of problems such as power surges and power failures.
l PDU — Uses circuit breakers to ensure that the AC current load does not exceed the PDU's rating.
l 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.
l 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.
l 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.
