9. USB 2.0 connectors (10-1 pin USB910, USB1112)
These connectors are for USB 2.0 ports. Connect the USB module cable to any of

chassis. These USB connectors comply with USB 2.0 specifications and supports up to
480Mbps connection speed.
H81M-V PLUS USB2.0 connectors
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
The USB 2.0 module is purchased separately.
10. Chassis intrusion connector (4-1 pin CHASSIS)
This connector is for a chassis-mounted intrusion detection sensor or switch. Connect
one end of the chassis intrusion sensor or switch cable to this connector. The chassis
intrusion sensor or switch sends a high-level signal to this connector when a chassis
component is removed or replaced. The signal is then generated as a chassis intrusion
event.
By default, the pin labeled "Chassis Signal" and "Ground" are shorted with a jumper
cap. Remove the jumper caps only when you intend to use the chassis intrusion
detection feature.
