PCI Board Selector, SW1
The CM17320HR uses a rotary switch to select the PCI slot. Before you can use this module you
have to set the PCI board selector switch. The procedure is if this module is the first module from
the CPU module select ’0,’ if it is the second module select ’1,’ etc. Positions 4 - 7 are simply
repeats of positions 0 – 3.
