The configuration switch settings for SW1 depends on the revision of the
board. If the revision of the VPX6600 product is Rev G or earlier, use the SW1
switch settings shown in Table 3.1.a. If the revision of the VPX6600 product is
Rev H or later, use the SW1 switch settings shown in Table 3.1.b.

SW1-1 is reserved.
SW1-2 is used to select the interface on one of the expansion planes. The
expansion plane interface can either be one x4 PCIe connection or four
individual SATA III interfaces.
SW1-3 is used to configure the source of
the CPU’s RTC voltage. With a coin
-
cell battery installed, the CPU will use the coin-cell battery as the RTC voltage.
Turning SW1-3 on will use the VPX Battery input on Pin P1-G3 for the RTC
voltage.
WARNING: If SW1-3 is closed with a coin-cell battery installed, it will connect
the coin-cell to any voltage present on the VPX Battery pin on the VPX
connector P1-G3. The coin-cell battery must be removed before closing switch
SW1-3 if a voltage is supplied by the VPX backplane!
SW1-4 is unused.
