Intel Desktop Board D5400XS Product Guide Table 3 describes the LED states when the board is powered up and the LAN subsystem is operating. Table 3. LAN Status LEDs LED A B LED Color Green N/A Green Yellow LED State Off On Blinking Off On On Indicates LAN link is not established LAN link is established LAN activity is occurring 10 Mb/s data rate 100 Mb/s data rate 1000 Mb/s data rate USB 2.0 Support The Desktop Board supports up to 10 USB 2.0 ports (six ports routed to back panel connectors and four ports routed to two onboard headers). USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function at USB 1.1 speeds. In addition to USB 2.0 devices, USB 2.0 operation requires 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. Hard Disk and Optical Disk Drive Support This section describes the Desktop Board's support for hard disk and optical disk drives. The board supports IDE and Serial ATA (SATA) drives. Enhanced IDE Interface The board's IDE interface handles the exchange of information between the processor and peripheral devices such as hard disk drives and CD-ROM drives. The interface supports: • Up to two IDE devices (such as hard drives) • ATAPI-style devices (such as CD-ROM drives) • Older PIO Mode devices • Ultra DMA-33 and ATA-66/100 protocols 16
