24 ASPB Installation
Removing Analog Audio I/O Boards (PDR100 ONLY)
NOTE: If you are not upgrading a PDR 100 proceed to the next step,
“Installing the ASPB In Recommended Slot Locations” on page 26.
You must remove all Analog Audio I/O boards from the PDR100 before
installing the ASPB.
To remove all the Analog Audio I/O boards:
1. Remove all interface cables from the rear of the Analog Audio I/O boards if
you have not done so already. Refer to the rear panel labeling to help identify
the Analog Audio I/O boards.
2. Disconnect and remove all internal coaxial clock cables connected between
the Analog Audio I/O boards and video boards.
3. Remove the circuit board mounting screw inside the chassis for each Analog
Audio I/O board using the Torx tool with the T15 tip ( Ê in Figure 3).
CAUTION: To avoid damage to the circuit board when removing or
installing it:
- Do not rock the circuit board in the EISA bus connector—pull straight
up to remove.
- Do not grasp or push on the rear-panel connectors when removing or
installing circuit boards in the card slots.
4. Carefully grasp the Analog Audio I/O board and lift upward to free the
circuit board from the motherboard connectors.
NOTE: If you have difficulty removing the circuit boards:
- It may be necessary to remove the screw mounting an adjacent circuit
board.
- It may be necessary to remove an adjacent tall circuit board to ease
removal of the shorter Analog Audio I/O board. Use the following
procedure to remove adjacent tall circuit boards.
