2.3 Physical Parameters

This section has two parts: the first illustrates the distances between the board mounting holes and the edges of the board; the second shows the vertical clearances required by the board components at all points within the border of the AlphaPC 164UX.

All holes and board measurements are compliant with the ATX 2.01 specification. The AlphaPC 164UX exceeds the ATX height indications in two places. The first is at the location of the 21164 (the 2.5’ region).The second is at the location of the SCSI connectors(the 1.0’ region to the left of the second PCI slots).

The AlphaPC motherboard is an ATX-size printed wiring board (PWB) with the fol- lowing dimensions:

•Length: 30.48 cm (12.0 in ( 0.0005 in)

•Width: 24.38 cm (9.6 in ( 0.0005 in)

•Height: 6.86 cm (2.7 in)

The board can be used in certain desktop and deskside systems that have adequate clearance for the 21164 heat sink and its cooling fan. All ISA and PCI expansion slots are usable in standard desktop or deskside enclosures.
