l Wake on mouse or keyboard, which, when using Personal System/2 (PS/2) devices, allows you to start the system from the sleep state by

pressing a key or moving the mouse.

l Remote Wake Up capability, which, when enabled in the System Setup program, allows you to start the system from a server management

console. Remote Wake Up capability also allows remote system setup, BIOS upgrades, software downloading and installation, file updates,

and asset tracking after hours and on weekends when local area network (LAN) traffic is at a minimum.

l Universal Serial Bus (USB) capability, which simplifies connection of peripheral devices such as keyboards, printers, and speakers. The

USB connectors on the system's back panel provides two connection points for multiple USB-compliant devices. USB-compliant devices

can be connected and disconnected while the system is running.

l A modular mini tower computer chassis with a minimum number of screws for easy disassembly and improved serviceability.

l A high-speed, high-resolution AGP 4X or AGP Pro card. (Documentation from the video card manufacturer is included with the system.)

AGP Pro (4X) improves graphics performance by providing a dedicated bus for a faster interface between the video subsystem and system

memory. AGP also allows conventional memory to be used for video-related tasks.

l An optional LS-120 SuperDisk drive capable of storing up to 120 MB of data per diskette.

The system board includes the following integrated features:

l Four 32-bit PCI expansion slots including one 32-bit PCI/redundant array of independent disks (RAID) expansion slot that has an extension

for an optional RAID upgrade.

l Two 64-bit 66-MHz PCI expansion slots.

l One AGP Pro expansion slot.

l A diskette drive interface, which supports a 3.5-inch diskette drive.

l Ultra Advanced Technology Attachment (ATA)/66 support, which allows ATA/66 enabled devices to transfer data at speeds of up to 66 MB

per second (MB/sec). The two ATA/66 channels support up to four EIDE devices. The primary and secondary EIDE channels support up to

two devices each, such as EIDE CD-ROM drives and EIDE tape drives.

l SCSI support using two integrated SCSI channels.

¡ The primary channel provides Ultra 160/M low-voltage differential (LVD) (160-MB/sec) support for high-performance SCSI hard-disk

drives and an optional RAID subsystem that requires an optional RAID card. This channel also supports Ultra2 and Ultra SCSI devices.

¡ The secondary channel provides support for external Ultra/Wide (40-MB/sec) SCSI devices, such as scanners, and for internal narrow

SCSI devices, such as CD-ROM drives, tape drives, and optical drives. The maximum total length of the external cable on the

secondary channel is .5 m with eight devices or 1 m with four devices.

l Two high-performance serial ports and one bidirectional parallel port for connecting external devices.

l A PS/2-style keyboard port and a PS/2-compatible mouse port.

An integrated 10/100-megabit-per-second (Mbps) 3Com

PCI 3C920 based and 3C905B-TX compatible Ethernet network interface

controller (NIC) with Remote Wake Up support.

ThefollowingsoftwareisincludedwithyourDell™computersystem:

l Utilities that safeguard the system and enhance the operation of its hardware features; for example, the AutoShutdown service lets you

perform an orderly shutdown with a single touch of the power button.

l Graphics drivers.

NOTE: If a BIOS upgrade is required, download the flash BIOS file from the file library at

http://support.dell.com, and run the executable file to create a bootable diskette image that will

automatically flash the system BIOS when the system is booted with the diskette.

NOTE: Windows NT 4.0 does not support USB devices; however, your Dell Precision WorkStation 620 computer system

supports a USB keyboard through its BIOS.

NOTE: An AGP Pro (4X) graphics adapter expansion card may require the AGP Pro expansion slot and 1 or 2 adjacent PCI

slots.

NOTE: Backup copies of most drivers for your system are included on the Dell Precision ResourceCD. If you need to

reinstall any of these drivers, see the documentation that accompanies the CD.

NOTE: Windows 2000 does not require the AutoShutdown utility to be loaded.
