Height of VXIpc-860 Plug-In Boards
In general, the VXIpc-860 can accommodate any standard-size PCI
card and any XT-height ISA card. The height of an I/O card is measured
from the bottom of the bus connector to the top of the board, as shown
in Figure F-4.
Figure F-4. I/O Board Dimensions for VXIpc-860 Expansion Slot
Both XT-height ISA cards and PCI cards are 4.2 in. high. The
VXIpc-860 does not support AT-height ISA cards, which are
4.8 in. high.
Length of VXIpc-860 Plug-In Boards
The VXIpc-860 can accommodate PCI or ISA I/O boards that are up to
4.2 in. high and up to 8.4 in. long. When DRAM SIMMs 0.85 in. are
used on the processor board, the component-side component height on
a PCI I/O board shall be 0.48 in. tall in the area shown in Figure F-4.
For the same height DRAM SIMMs, the ISA I/O board solder-side
component height shall be 0.07 in. tall in the area shown in Figure F-4.
Be sure to allow for clearance if you want to use taller DRAM SIMMs.
