Replacing System Board
This section describes how to remove and replace the Silicon Graphics 230 Visual
Workstation system board.
Follow electrostatic discharge (ESD) precautions. Electronic equipment can be
irreparably damaged by ESD. Always follow these preventative measures when
handling a system component:
• Remove a component from its antistatic bag only when you are ready to install it.
• If you have to handle a component before installation, do not place it on surfaces
that produce ESD (carpeting, for example), or near devices that create static
electricity.
• Attach a static wrist strap to a grounded connection on your system when installing
or removing a component.
The following instructions describe how to remove the Silicon Graphics 230 Visual
Workstation system board:
1. Remove the side panel as shown in “Pre-installation Instructions” on page 16.
2. To facilitate the removal of system components, rest the chassis on its right side on a
padded surface so as not to scratch the system.
3. Remove all expansion boards. Refer to “Replacing Expansion Cards” on page 39 for
the removal of expansion boards.
4. Disconnect all cables from the system board.
