Other Front Panel Connectors
In addition to the front panel I/O connector, there are three other headers included in the front
panel group. Two headers (front panel header #2 and pwr/HDD LED header) provide
duplicate signals to those available on the front panel I/O connector. The following tables list
the pinouts and signals on the remaining front panel connectors.
Memory/Expansion Connectors
The CU430HX system board provides six 72-pin SIMM sockets for main memory. These
sockets accept standard SIMM 72-pin modules.
The CU430HX system board uses a PCI/ISA riser connector (J6J2) to provide for expansion
PCI or ISA boards. The associated riser board can support either two or three PCI slots. A
pair of jumpers on the CU430HX system board must be set to define the number of PCI slots
on the riser board. Refer to Appendix C for jumper block details. Table A-
pinout listing for the PCI/ISA riser connector.
