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 48)

  PS/2 keyboard and mouse
  USB (four ports)
  Parallel port
  Serial port A
  VGA port
  LAN (optional)
  Audio (line out, line in, and mic in)

• Internal I/O connectors (see page 49)

  Audio (auxiliary line input, ATAPI CD-ROM, and front panel audio)
  Fans
  Power
  Add-in boards (PCI)
  IDE
  Diskette drive
  Chassis intrusion

• External I/O connectors (see page 54)

  Auxiliary front panel power/sleep/message-waiting LED

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
