Intel SYS7180VE Front Panel Connector J1, 2.5.2USB Connector USB1-2 USB3-4, Power switch, Speaker

CHAPTER 2 –Hardware Installations

2.5.1 Front Panel Connector: J1

This header can be connected to a front panel power switch. The front panel connector includes headers for these I/O connections:

Power switch

Power LED

This header can be connected to an LED that will light when the computer is powered on.

Hard drive activity LED

This header can be connected to an LED to provide a visual indicator that data is being read from or written to an IDE hard drive. For the LED to function properly, the IDE drive must be connected to the onboard IDE controller.

Speaker

A speaker can be installed on the SYS7180VE as a manufacturing option. The speaker is enabled by a jumper on pins 2, 4, 6, 8 of the front panel connector. Removing the jumper can disable the onboard speaker, and an offboard speaker can be connected in its place. The speaker (onboard or offboard) provides error beep code information during the POST in the event that the computer cannot use the video interface. The speaker is not connected to the audio subsystem and does not receive output from the audio subsystem.

CHAPTER 2 –Hardware Installations

2.5.2USB Connector: USB1-2 USB3-4

Note: USB cable is special designed for SYS7180VE

The Universal Serial Bus (USB) that allows plug and play computer peripherals such as keyboard, mouse, joystick, scanner, printer, modem/ISDN, CD-ROM and floppy disk drive to be automatically detected when they are attached physically without having to install drivers or reboot.

The USB connectors allow any of several USB devices to be attached to the computer. Typically, the device driver for USB devices is managed by the operating system. However, because keyboard and mouse support may be needed in the Setup program before the operating system boots, the BIOS supports USB keyboards and mice.

The CPU card has four USB ports; one USB peripheral can be connected to each port. For more than four USB devices, an external hub can be connected to either port. The four USB ports are implemented with stacked back panel connectors. The CPU card fully supports the universal host controller interface (UHCI) and uses UHCI-compatible software drivers.

USB features includes:

Self-identifying peripherals that can be plugged in while the computer is running

Automatic mapping of function to driver and configuration

Support for synchronous and asynchronous transfer types over the same set of wires

Support for up to 127 physical devices

Guaranteed bandwidth and low latencies appropriate for telephony, audio and other applications

Error-handling and fault-recovery mechanisms built into the protocol
