To install the new Expansion Adapter board:
1. Align the board connectors with the backplane connectors and firmly
insert the board.
CAUTION
Do not rock the board back and forth, which may damage the
connectors. Press evenly on the top of the board between the two
connectors to seat the board.
2. Connect the Adapter cable to the board’s external connector.
3. Replace the side panel and top cover. Ensure the top cover is installed
properly so the safety interlock switch is engaged.
Opening the Workstation Base Unit
Open the base unit only when servicing the Geometry Accelerator, Host
Adapter, or VGA boards.
This section describes removing the top cover, left side panel, and PCI
access panel. It also describes where to clip an antistatic wrist strap to the
chassis for the best static discharge prevention. Use a quarter-inch nutdriver
to remove all the screws mentioned in this section.
Note: Face the front of the base unit to determine which is the left side
panel, and which is the right side panel.
WARNING
Before opening the base unit, shut the system down; then, turn the
system power off. Leave the power cord connected to the AC outlet to
maintain ground.
