Mass Storage; Serial Interface; Universal Serial Bus Interface; Network Interface Controller - HP 8100 - Elite Convertible Minitower PC Technical Reference Manual

System Overview

2.3.5 Mass Storage

All models support at least two mass storage devices, with one being externally accessible for
removable media. The hard drive controller supports SATA 1.5- and 3.0-Gb/s hard drives in the
following quantities:
SFF: four SATA interfaces (one SATA port available for eSATA port option)
CMT: five SATA interfaces (one SATA port available for eSATA port option)
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

Aserial port is accessible at the rear of the chassis. These systems 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. 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 an Intel 82578 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), Alert Standard Format (ASF), and AMT features. An RJ-45 connector
with status LEDs is provided on the rear panel.
