Chapter 3 – Installation
3-5
Warning
Disconnect all external power supplies before you open and service any piece of
equipment. Also, always use static protection when handling CPU boards.
Caution
Verify the positions of all jumpers and switches on the CPU board before installation.
Check configurations with the lists and diagrams in the manual that accompanies the
CPU board.
Note
Before connecting a ribbon cable to latched connectors, make sure that the latches are
pulled down near the surface of the board. When the cable connection is made, the
latches snap up. When removing a cable connector, move the latches down near the
board. This nudges the connector up so you can remove it easily.
Installing the CPU Board
1.
Disconnect all power supplies from both the monitor and computer modules.
2.
If the computer module is mounted to the monitor module, remove the computer
module, as described in
Removing the Computer Module
, later in this chapter.
3.
Remove the five screws that secure the top cover to the computer module. Save the
screws in a location where you can locate them later.
4.
Verify all jumper settings.
5.
Hold cables FDD, HDD-I, COM1, COM2, LED and KEYBOARD toward the side of
the CPU module.
6.
Place the CPU card into slot 0 in the passive backplane. Push the card down 3/4 of
the way.
7.
Attach flat cables FDD, HDD-I, COM1, COM2, LED, and KEYBOARD to the re-
spective connectors on the CPU board. Push down on the card evenly until it firmly
seats into the card edge connector.
8.
Secure the ORB with one screw at the top.
9.
Close the top cover and re-install and tighten the screws. If the computer module was
mounted to the monitor module, refer to
Replacing the Computer Module
, later in
this chapter, for re-installation instructions.
10.
Connect power sources and external cables previously disconnected.
The 9457 is now ready for operation.
