Connecting to the Front Panel USB 2.0 Headers
Before connecting to the USB headers, observe the precautions in "Before You Begin"
on page 25. See Figure 12, B and G for the location of the USB 2.0 headers. Table 7
and Table 8 show the pin assignments for the headers.
The brown USB header (Figure 12, B) provides a single USB port while the black USB
header (Figure 12, G) provides two USB ports. The single USB port header is designed
to support a Flash Memory Drive such as the Intel Z-U130 USB Solid-State Drive (or
compatible device). Refer to “Installing an Intel
®
Z-U130 USB Solid-State Drive or
Compatible Device” on page 34 for more information.
