System Overview

2.4.5 Mass Storage

All models support at least two mass storage devices, with one being externally accessible for removable media. These systems provide the following intefaces for internal storage devices:

USDT: one SATA interface, one SATA-to-PATA bridge/interface for a Slimline optical drive

SFF/ST: three SATA interfaces

MT/CMT: four SATA interfaces

These systems may be preconfigured or upgraded with a 80-, 160-, or 250-GB SATA hard drive and one removable media drive such as a CD-ROM drive.

2.4.6 Serial and Parallel Interfaces

All models except those that use the USDT form factor include a serial port and a parallel port, both of which are accessible at the rear of the chassis. The USDT form factor may be upgraded with an adapter to provide serial and parallel ports. The SFF, ST, MT, and CMT form factors may be upgraded with an optional second serial port.

The serial interface is RS-232-C/16550-compatible and supports standard baud rates up to 115,200 as well as two high-speed baud rates of 230K and 460K. The parallel interface is Enhanced Parallel Port (EPP1.9) and Enhanced Capability Port (ECP) compatible, and supports bi-directional data transfers.

2.4.7 Universal Serial Bus Interface

All models provide eight Universal Serial Bus (USB) ports, with two ports accessible at the front of the unit and six ports accessible on the rear panel. The USB interface provides hot plugging/unplugging functionality. These systems support USB 1.1 and 2.0 functionality on all ports.

2.4.8 Network Interface Controller

All models feature a Intel 82566 Gigabit Network Interface Controller (NIC) integrated on the system board. The controller provides automatic selection of 10BASE-T, 100BASE-TX, or 1000BASE-T operation with a local area network and includes power-down, wake-up, and Alert-On-LAN (AOL), and Alert Standard Format (ASF) features. An RJ-45 connector with status LEDs is provided on the rear panel.
