MPEG Board Upgrade Installation
12 MPEG Board Upgrade Installation
Installing Boards in an Option MG Unit
To install one or two MPEG boards in an MPEG-ready PDR 200 (Option MG with
serial number B030000 or above):
1. Remove the three-slotted PCI Interconnect board and remove all cables
connected Profile boards, such as SCSI, Sharcnet, or audio clock cables
(look at Figure 7 on page 23 if you need help identifying the Sharcnet and
audio clock cables). Label each cable before removing it and draw a simple
diagram to make it easier to reconnect the cables later. Remove any cable tie
wraps, if necessary.
CAUTION: Be certain to label the SCSI cables before removing them so that
you can reconnect them properly. If the A and C SCSI cables are reversed,
the file system will be corrupted.
2. Remove the slot cover for slot J8. If you are installing two MPEG boards,
also remove the slot cover for J12.
CAUTION: Forcing the board into the slot may result in bent connectors on
the mother board. Carefully follow the instructions in step 3 to avoid
damaging hardware.
3. Install an encoder board (P2MPG12) 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. To install the boards correctly:
- Align the board with the connectors on the motherboard. Make sure that
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 another 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.
