MPEG Board Upgrade Installation
1. Install the MPEG boards. An encoder board (P2MPG12) should go in slot J8
and a decoder board (P2MPG04) in J12. If you are installing two encoder
boards or two decoder boards, slot order doesn’t matter. Also, reinstall the
video I/O and audio boards that you had to move out to make room for the
MPEG boards. To install the boards correctly:
- Align the boards with the connectors on the motherboard. Make sure the
board is in the board guide at the front edge.
- With the extractor on the front end of the board in the up position, press
down on the board firmly until it is seated.
- As you push the board into the connectors, you will feel the board engage
first one, then a second set of contacts in the connector. The board is
properly seated when the top of the rear mounting bracket is resting on the
rear chassis wall shelf.
2. Install the slot cover screws. Use the Torx tool with the T15 tip to install the
mounting screws in the top of the slot cover insidethechassis (
Ê
on page 13) and through the rear panel at the bottom of the slot cover (
Ë
in
Figure 4).
3. Connect the SCSI cables, as shown in Figure 5 on page 14.
4. Install the five-slotted PCI Interconnect board. This board is a high-speed
bus used to move data between boards with PCI connectors. Align the center
keys on the PCI Interconnect board with the keys on the Master EDR board
in slot J10. Using appropriate pressure, press down firmly on the
interconnect board to ensure that it is properly seated (see Figure 6 on
page 15).
5. Connect the audio clock and Sharcnet cables according to the diagram you
drew earlier or see “Audio Clock and Sharcnet Cabling” on page 21.
6. Follow the reassembly instructions under the heading “Reassembling the
