INSTALLING THE MAINBOARD
Before starting, check the location of the mounting holes in the case and on the mainboard.
Caution: Static electricity can damage the mainboard.
Install the mainboard as follows:
1.
Review the section on static electricity precautions at the beginning of this manual.
2.
Place the case on an anti-static mat and remove the cover. Remove the nylon stand-offs and
screws for mounting the mainboard.
3.
Put the front of the case to the right and the rear to the left. The mainboard occupies the
section of the case nearest the user; the power supply goes on the far side.
4.
Align the mounting holes on the case to the mounting holes on the mainboard. Make sure to
access the keyboard connector once the board is installed.
5.
From the bottom of the mainboard, insert stand-offs into the proper holes on the board, and
attach the mounting screws to the bottom of the case.
Note:
Some cases do not use stand-offs and mounting screws; in this case user can fasten the
mainboard into the case with regular screws.
6.
Place the mainboard into the case and fasten the board securely with regular screws.

CONNECTION THE MAINBOARD
Once the mainboard has been fastened into the system case, the next step is to connect the internal
cables. The internal cables are wire leads with plastic female connectors that attach to the connectors.
The mainboard connectors have varying numbers of pins and are the points of contact between the
mainboard and other parts of the computer.
A description of each connector and its connector pins follows. See Fig 7 for the location of the
connectors on the mainboard.
Note:
Before making connectors on the board, make sure that power to the system is turned off.
