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.

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.

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
