System Overview

2.3.5 Mass Storage

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

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

SFF: three SATA interfaces

CMT: four SATA interfaces

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

2.3.6 Serial and Parallel Interfaces

The SFF and CMT form factors include a serial port and a parallel port, both of which are accessible at the rear of the chassis. The SFF and CMT form factors may be upgraded with a second serial port option.

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.

2.3.7 Universal Serial Bus Interface

All models provide ten Universal Serial Bus (USB) ports. Two ports are accessible at the front of the unit, six ports are accessible on the rear panel, and two ports are accessible on the system board. The SFF and CMT form factors support a media card reader module that connects to the two internal ports. These systems support USB 1.1 and 2.0 functionality on all ports.

2.3.8 Network Interface Controller

All models feature an Intel 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, Alert-On-LAN (AOL), Alert Standard Format (ASF), and Active Management Technology (AMT) features. An RJ-45 connector with status LEDs is provided on the rear panel.
