16 MPEG Board Upgrade Installation
Installing Boards in a non-Option MG Unit
A non-Option MG PDR 200 (with serial number B030000 or above) already has
the Master and Slave EDR boards in the correct slots (see Table 3 on page 5), but
it is possible that you have analog composite or serial digital component I/O
boards installed in slots J8 or J12. These boards must be removed and installed in
other slots in order to install MPEG boards.
To install MPEG boards in a non-Option MG PDR200:
1. Remove the three-slotted PCI Interconnect board and remove all cables
connected to 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. If there are analog composite or serial digital component I/O boards installed
in slots J8 or J12, remove the boards. For complete instructions on removing
circuit boards, see “Removing Circuit Boards” on page 18.
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 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. To install the boards
correctly:
