ASUS P5Q-EM 1-37
4. USB connectors (10-1 pin USB78; USB910; USB1112)
These connectors are for USB 2.0 ports. Connect the USB module cable
to any of these connectors, then install the module to a slot opening at the
back of the system chassis. These USB connectors comply with USB 2.0
specification that supports up to 480 Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
If your chassis supports front panel USB ports, you can attach a front panel
USB cable to these connectors. Connect the USB cable to ASUS Q-Connector
(USB, blue) first, and then install the Q-Connector (USB) to the USB connector
onboard.
We highly recommend that you connect this
eSATA port to an eSATA external hard disk
drive using an eSATA to eSATA cable. DO
NOT connect the eSATA port to a SATA hard
disk drive using a eSATA to SATA cable.
The bundled eSATA module
allows you to add an eSATA port
on the back of your chassis. To
install the eSATA module, connect
the SATA cable connector to
any of the onboard SATA 1–6
connectors and then screw the
bracket to the chassis.
