The following sections tell how to make each connection. In most cases, you will sim-
ply need to connect a standard cable. All of the connector pin assignments are
shown in Appendix B.
Warning! Always completely disconnect the power cord from your chassis when-
ever you are working on it. Do not make connections while the power is
on. Sensitive electronic components can be damaged by a sudden rush
of power. Only experienced electronics personnel should open the PC
chassis.
Caution! Always ground yourself to remove any static charge before touching the
CPU card. Modern electronic devices are very sensitive to static electric
charges. Use a grounding wrist strap at all times. Place all electronic
components on a static-dissipative surface or in a static-shielded bag
when they are not in the chassis.

System Memory
The PCI-7030 series has one socket for a 200-pin SODIMMx1. This sockets use 1.8
V un-buffered double data rate synchronous DRAMs (DDR SDRAM). They are avail-
able in capacities of 256, 512, and 1024 MB. The sockets can be filled in any combi-
nation with DIMMs of any size, giving a total memory size between 256 MB and 2
GB. PCI-7030 series does NOT support ECC (error checking and correction).

Memory Installation Procedures
To install SODIMMs, first make sure the two handles of the SODIMM socket are in
the "open" position. i.e. The handles lean outward. Slowly slide the SODIMM module
along the plastic guides on both ends of the socket. Then press the SODIMM module
right down into the socket, until you hear a click. This is when the two handles have
automatically locked the memory module into the correct position of the SODIMM
socket. To remove the memory module, just push both handles outward, and
the memory module will be ejected by the mechanism in the socket.
