2.4.5 Mass Storage
All models support at least two mass storage devices, with one being externally accessible for
removable media. These systems provide one, two, or four SATA interfaces and one PATA
interface. These systems may be preconfigured or upgraded with a 40-, 80-, or 160-GB SATA
hard drive and one removable media drive such as a CD-ROM drive. Some systems also provide
one MultiBay interface.
2.4.6 Serial and Parallel Interfaces
All models except those that use the USDT form factor include a serial port and a parallel port,
both of which are accessible at the rear of the chassis. The USDT form factor may be upgraded
with an adapter to provide serial and parallel ports. The SFF, ST, MT, and CMT form factors may
be upgraded with an optional second serial port.
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.

of the unit and six ports accessible on the rear panel. The USB interface provides hot
plugging/unplugging functionality. These systems support USB 1.1 and 2.0 functionality on all
ports.
2.4.8 Network Interface Controller
All models feature a Broadcom NetXtreme 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, and Alert-On-LAN (AOL), and Alert Standard Format (ASF) features. An RJ-45
