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: two SATA interfaces

SFF: three SATA interfaces and one eSATA port

CMT: four SATA interfaces and one eSATA port

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 Interface

The SFF and CMT form factors include a serial port 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.

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 through a header on the system board. The SFF and CMT form factors support a media card reader module that connects to the internal header. These systems support USB 1.1 and 2.0 functionality on all ports.

BIOS Setup allows for the disabling of USB ports individually or in groups. In order to secure the system against a physical attack, ports may be disabled even if there is nothing physically connected to them, such as the two front ports for the media card reader module when the module is not present.

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 AMT features. An RJ-45 connector with status LEDs is provided on the rear panel.
