System Overview

2.3.5 Mass Storage Accommodations

All models support at least two mass storage devices, with one being externally accessible for removable media. The storage device accommodations are as follows:

CMT: six bays total; three 5.25-inch externally accessible, three 3.5-inch internal

MT: five bays total; two 5.25-inch externally accessible, one 3.5-inch externally acessible, two 3.5-inch internal

SFF: three bays total; one 5.25-inch externally accessible, one 3.5-inch externally accessible, one 3.5-inch internal

USDT: two bays total; one 5.25-inch externally accessible (for slimline optical disk drive), one 2.5-inch internal

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 Legacy Input/Output Interfaces

PS/2 Port

All systems provide two PS/2 ports at the rear of the chassis for connection of a keyboard and mouse.

Serial port

The CMT, MT, and SFF form factors provide a serial port at the rear of the chassis and support 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.

Parallel port

The CMT, MT, and SFF form factors support a parallel port option.

2.3.7 Universal Serial Bus Interface

All models provide ten externally accessible Universal Serial Bus (USB) ports. Four ports are provided at the front of the unit, six ports are provided on the rear panel. Accessible through a header on the system board are two USB ports in the USDT form factor and four USB ports in the CMT, MT, and SFF form factors. These systems support a media card reader module that connects to the internal header. USB 1.1 and 2.0 functionality is available 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 82579 gigabit (GbE) 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), and AMT features. An RJ-45 connector with status LEDs is provided on the rear panel.
