Connectors, Headers And Switches - Abit SE6 User Manual

Installing the Motherboard
Step 1. Before you install the memory module, please place the computer power switch in the "OFF"
position and disconnect the AC power cord.
Step 2. Remove the computer's chassis cover.
Figure 2-4. Memory module installation
Step 6. Once the DIMM module has been installed, the installation is complete and the computer's cover
can be replaced. Or you can continue to install other devices and add-on cards that are mentioned
in the following section.
Note: When you install a DIMM module fully into the DIMM socket, the eject tab should be locked
into the DIMM module very firmly and fit into its indention on both sides.
It is difficult to differentiate between the PC100, PC133 SDRAM and VCM DRAM modules from the
exterior. The only way to identify them is through the sticker on the RAM module.

2-4. Connectors, Headers and Switches

Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are
usually connected one-by-one to connectors located on the motherboard. You need to carefully pay
attention to any connection orientation the cables may have and, if any, notice the position of the first pin
of the connector. In the explanations that follow, we will describe the significance of the first pin.
We will show you all of the connectors, headers and switches here, and tell you how to connect them.
Please pay attention and read the entire section for necessary information before attempting to finish all of
the hardware installation inside the computer chassis.
Figure 2-5 shows you all of the connectors and headers that we'll discuss in the next section, you can use
this diagram to visually locate each connector and header we describe.
All connectors, headers and switches mentioned here will depend upon your system configuration. Some
features you may (or may not) have and need to connect or configure depending on the peripheral. If your
system doesn't have such add-on cards or switches you can ignore some special feature connectors.
Step 3. Before touching any electronic components,
make sure you first touch an unpainted,
grounded metal object to discharge any static
electricity stored on your clothing or body.
Step 4. Locate your computer's 168-pin memory
expansion DIMM socket.
Step 5. Insert the DIMM module into the expansion
socket as shown in the illustration. Note how
the module is keyed to the socket. You can refer
to figure 2-4 for the details. This insures the
DIMM module will be plugged into the socket
in one way only. Firmly press the DIMM
module into the DIMM socket, making certain
the module is completely seated in the DIMM
socket.
