Shogun Power distribution board upgrade (Quad
processor support)
Check before fitting a second dual CPU card
In Shogun systems fitted with the Pentium motherboard it is important to
check, prior to fitting a second dual CPU card, that the Power Distribution Board is REV D
or later. Early Shogun models were supplied fitted with a REV B Power Distribution Board.
The REV B board is satisfactory in systems with two single CPU cards, or
one dual CPU card. However, the fitting of a second dual CPU card requires that the system
be upgraded to the REV D or later Power Distribution Board.
For information about the location and possible removal of this board
please refer to the detailed instructions in the Owner's Handbook.
Revision differences
The revision markings of the Power Distribution Board are not easily
viewable when the board is in situ, but there is one important feature which makes it
readily identifiable:
- The REV B Power Distribution Board has a low profile encapsulated voltage
regulator module in the centre of the board. Module size approx. 50 mm square and 12 mm
high.
- The REV D Power Distribution Board has a large multi-finned heatsink
approx. 80 x 100 mm and 35 mm high, the edge of which is at the side of the board, and it
is immediately in view when the inner cover plate is removed.
As confirmation, on removal, the board silk screening will have the
version marked as /B or /D on the component side, at the end nearest the computer front.
Apricot TSD also have a list of serial numbers of those machines
initially installed with REV B Power Distribution Boards.
The replacement Part Number for REV D Power Distribution Board is:
