System Overview

2.3.5 Mass Storage

These systems provide four SATA interfaces for mass storage devices. The SFF supports up to two removeable media devices and one internal hard drive. The MT supports up to three removeable media devices and two hard drives, and is available in factory-preconfigured RAID configurations.

Supported SATA hard drives:

■SMART IV, 3.0 Gb/s, 7200 RPM drive sizes (GB): 80, 160, 250, 500

■SMART III, 3.0 Gb/s, 10000 RPM drive sizes (GB): 80, 160 Supported SATA removeable media drives:

■DVD-ROM drive

■SuperMulti LightScribe DVD Writer Drive (requires special label-etchable media)

2.3.6Serial Interface

These systems include a serial port accessible 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.

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. These systems 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 a Broadcom 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.
