Technical Reference 2.8 Connectors CAUTION Only the back panel USB, front panel USB, VGA, and PS/2 connectors have overcurrent protection. The desktop boards' internal connectors are not overcurrent protected and should connect only to devices inside the computer's chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computer's chassis. A fault in the load presented by the external devices could cause damage to the computer, the interconnecting cable, and the external devices themselves. This section describes the board's connectors. The connectors can be divided into these groups: • Back panel I/O connectors (see page 46) ⎯ PS/2 keyboard and mouse ⎯ USB (two ports) ⎯ Parallel port ⎯ Serial port A ⎯ VGA port ⎯ LAN (optional) ⎯ Audio (line out, line in, and mic in) • Internal I/O connectors (see page 47) ⎯ Audio (auxiliary line input, ATAPI CD-ROM, and front panel audio) ⎯ Fans ⎯ Power ⎯ Add-in boards (PCI) ⎯ IDE ⎯ Diskette drive ⎯ Chassis intrusion (optional) • External I/O connectors (see page 52) ⎯ Serial Port B (optional) ⎯ Auxiliary front panel power/sleep LED ⎯ Front panel (power/sleep LED, power switch, hard drive activity LED, reset switch, and auxiliary front panel power LED) ⎯ Front panel USB (one connector for two ports) NOTE When installing the board in a microATX chassis, make sure that peripheral devices are installed at least 1.5 inches above the main power connector, the diskette drive connector, the IDE connector, and the DIMM sockets. 45
