ERX-B75 User’s Manual 2.2 Installation Procedure This chapter explains you the instructions of how to setup your system. 1. Turn off the power supply. 2. Insert the DIMM module (be careful with the orientation). 3. Insert all external cables for hard disk, floppy, keyboard, mouse, USB etc. except for flat panel. A CRT monitor must be connected in order to change BIOS settings to support flat panel. 4. Connect power supply to the board via the ATX Power. 5. Turn on the power. 6.
ERX-B75 User’s Manual 2.3 Jumper and Connector List You can configure your board to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3.
