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. The optional RAC must be installed in PCI slot 7.

An integrated VGA-compatible video subsystem with an ATI Radeon 7000, 33-MHz PCI video controller. This video subsystem contains 16 MB 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 RAC is installed, the integrated video subsystem is disabled and

the video controller on the RAC is used instead.

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.

Standard baseboard management controller with serial access.

Back-panel connectors include serial, video, SCSI (optional), two USB connectors, and two NIC connectors.

Front-panel connectors include a video and two USB connectors.

Front-panel LCD display for system ID and error messaging.

System ID button on the front and back panels.

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.
