2.10 Wireless Bluetooth
If Bluetooth is desired, the motherboard could support a USB Bluetooth module, or
Bluetooth could be supported with a mini PCIe module that also supports Wi-Fi. If a
discrete module is used then it is preferred that the module be implemented via a USB
cable to an internal motherboard USB header, so the Bluetooth module can be placed
in an appropriate position in the system.
2.11 Monitor Switch
The motherboard must provide a “Monitor Switch” header for connectivity of a chassis
button that would turn off the flat panel display’s backlight unit. Additional
desirable/optional functions for this header may be simultaneously muting built-in
speaker audio, switching to alternate video inputs (if available), or other related
functionality.
Connector must be 1x2 railed, 2.54mm pitch and colored white.
