Intel Desktop Board DZ77GA-70K Technical Product Specification 1.10 Bluetooth*/WiFi Module The WiFi/Bluetooth* module is supplemental hardware that is included with certain Desktop Boards (see Figure 6). Figure 6. Bluetooth/WiFi Module 1.10.1 Bluetooth Technology (Module) The Bluetooth Module enables the user to connect with a variety of Bluetooth enabled devices. Driver support is provided by Microsoft operating systems like Microsoft Vista and Microsoft Windows 7. The Bluetooth driver stack is supplied by Microsoft but some Bluetooth enable devices might provide additional Bluetooth features and for proper functioning of those features, will need their own supplied drivers installed. • CSR Bluetooth module (BC0401PC08) • Maximum data rate 3.0 Mb/s • Forward and backward compatibility with Bluetooth v1.1, v1.2, v2.0, and v2.1 • Integrated Antenna • Operating system support (Windows XP, Windows Vista, and Windows 7 both 32 bit and 64 bit) For information about Refer to Obtaining Bluetooth information and drivers library/aa362932(VS.85).aspx Product Description 1.10.2 WiFi 802.11 Wireless (Module) The WiFi Module enables the user to connect with a variety of WiFi enabled networks, access points and allows peer to peer connections. Driver support is provided by Microsoft operating systems like Microsoft Vista and Microsoft Windows 7 with additional support provided by the supplied WiFi driver included on the Driver DVD and online. • Ralink WiFi 802.11 (RT8070) • Range up to 300 meters • Supports the following: . IEEE 802.11B supports up to 11 Mb/s data rate . IEEE 802.11G supports up to 54 Mb/s data rate . IEEE 802.11N supports up to 150 Mb/s data rate • Integrated Antenna • Operating system support (Windows XP, Windows Vista, and Windows 7 both 32 bit and 64 bit) For information about Refer to Obtaining WiFi information and drivers library/aa362932(VS.85).aspx 1.11 Hardware Management Subsystem The hardware management features enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features, including the following: • Fan monitoring and control • Thermal and voltage monitoring • Chassis intrusion detection Intel Desktop Board DZ77GA-70K Technical Product Specification 1.11.1 Hardware Monitoring and Fan Control The hardware monitoring and fan control subsystem is based on the Winbond* W83677HG-I device, which supports the following: • Processor and system ambient temperature monitoring • Chassis fan speed monitoring • Power monitoring of +12 V, +5 V, +3.3 V, V_SM, +VCCP, and PCH VCC • SMBus interface 1.11.2 Fan Monitoring Fan monitoring can be implemented using Intel® Desktop Control Center or third-party software. For information about Refer to The functions of the fan headers Section 1.12.2.2, page 42 1.11.3 Chassis Intrusion and Detection The board supports a chassis security feature that detects if the chassis cover is removed. The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion header. When the chassis cover is removed, the mechanical switch is in the closed position...
