Advantech MIC-3368 manual Installing Sdram SODIMMs

from damage.

1.To avoid electric shock, always disconnect the power from your PC chassis before you work on it. Don't touch any components on the CPU card or other cards while the PC is on.

2.Disconnect power before making any configuration changes. The sudden rush of power as you connect a jumper or install a card may damage sensitive electronic components.

3.Always ground yourself to remove any static charge before you touch your CPU card. Be particularly careful not to touch the chip connectors. Modern integrated electronic devices, especially CPUs and memory chips, are extremely sensitive to static electric discharges and fields. Keep the card in its antistatic packaging when it is not installed in the PC, and place it on a static dissipative mat when you are working with it. Wear a grounding wrist strap for continuous protection.

1.7 Installing SDRAM (SODIMMs)

The MIC-3368 provides two 144-pin SODIMM sockets. Each socket accepts either 16, 32, 64, 128 or 256 MB SDRAM (for MIC-3368B). Also the 512MB SODIMM support for MIC-3368. The sockets can be filled in any combination with SODIMMs of any size, giving a total memory capacity between 16 and 512 MB. If only one SODIMM module is required, it can be installed in either SODIMM socket.

Since the MIC-3368 can operate at 66 or 100 MHz, we recommend using PC100-compliant SODIMMs. To enable the chipset's Error Checking and Correction (ECC) function, please use SODIMMs which support the ECC function. The procedure for installing SODIMMs appears below. Please follow these steps carefully.

1.Ensure that all power supplies to the system are switched off.

2.Install the SODIMM module. Install the SODIMM so that its gold pins point down into the SODIMM socket.

3.Slip the SODIMM into the socket at a 45 degree angle and carefully fit the bottom of the card against the connectors.

4.Gently push the SODIMM into the socket until the clips on the ends of the SODIMM sockets snap into place.

5.Check to ensure that the SODIMM is correctly seated and all connector contacts touch. The SODIMM should not move around in its socket.

NOTE: The SODIMM modules can only fit into sockets one way, in accordance with the keyed notches along the bottom edge of the modules. Their gold pins must point down into the SODIMM socket.
