Installing the System Board
NECC recommends that you contact NECC Technical Support for
assistance in removing or replacing the system board.
Install the system board as follows.
1.
Align the system board with its screw holes within the chassis.
The screw holes in the board should align with the holes in the chassis. The back panel
connectors should fit perfectly into the back of the chassis.
2.
Secure the board to the chassis with the six screws removed when the board was removed.
3.
Reconnect any cables that were disconnected from the system board.
4.
Replace the expansion boards (see “Installing an Expansion Board”).
5.
If appropriate, install any memory modules, processor, or cables from a previous board.
6.
Replace the system cover.
Minitower and Desktop Conversion
You can use the system as a minitower system by placing it in a vertical position, or you can
convert it to a horizontal position for use as a desktop system. You can also convert the system
back to a vertical position.
The accessible devices in the system can be positioned so they are upright for the minitower
configuration or for the desktop configuration.
The following sections describe how to convert between minitower and desktop configurations.
Converting from Minitower to Desktop
The system comes factory-shipped as a minitower. Convert the system for use as a desktop
system using the following steps.
Before converting the system, turn off system power and unplug the
system power cable. Power is removed only when the power cable is unplugged.
1.
Turn off and unplug the system and any peripherals.
2.
Disconnect any external options (such as a keyboard and monitor) from the front or rear of
the system unit.
3.
Remove the system cover and front panel (see “Removing the Cover” and “Removing the
Front Panel” earlier in this section).
4.
Remove any installed 5 1/4-inch devices, including the 5 1/4-inch two-device bracket
housing the 3 1/2-inch device (see “Removing a 5 1/4-Inch Accessible Device” earlier in
this section).
