User manual GIGABYTE U24F

[. . . ] Prior to installation, carefully read the user's manual and follow these procedures: • Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or warranty sticker provided by your dealer. These stickers are required for warranty validation. • Always remove the AC power by unplugging the power cord from the power outlet before installing or removing the motherboard or other hardware components. • When connecting hardware components to the internal connectors on the motherboard, make sure they are connected tightly and securely. [. . . ] Please note that memory module has a foolproof insertion design. A memory module can be installed In only one direction. Push down the memory and seat it firmly. Reverse the installation steps when you wish to remove the DIMM module. 1 2 Hardware Installation -9- 1-4 Back Panel Connectors b d b f a c e c g h i (a). DC In Port Connect the DC power to this port. (b). RJ-45 LAN Port The Gigabit Ethernet LAN port provides Internet connection at up to 1 Gbps data rate. The following describes the states of the LAN port LEDs. (c). USB 2. 0/1. 1 Port The USB port supports the USB 2. 0/1. 1 specification. Use this port for USB devices such as a USB keyboard/mouse, USB printer, USB flash drive and etc. (d). Serial Port Connects to serial-based mouse or data processing devices. (e). Video Port The video in port allows connect to video in, which can also apply to video loop thru function. (f). Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
