LAN Status LEDs
Two LEDs are built into the RJ-45 LAN connector located on the back panel (see
Figure 2). These LEDs indicate the status of the LAN.
Figure 2. LAN Status LEDs
Table 3 describes the LED states when the board is powered up and the LAN

Hi-Speed USB 2.0 Support
The Desktop Board supports up to 12 USB 2.0 ports (six ports routed to the back
panel and six ports routed to three internal headers) via ICH9. USB 2.0 ports are
backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at
USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support
USB 2.0 transfer rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports
to USB 1.1 operation. This may be required to accommodate operating systems that
do not support USB 2.0.
