If you have problems with your PCI-SCI interconnect, check the following items:
Verify that the LED on the PCI-SCI host adapter is blinking green rapidly. If it is not, refer to the documentation that came with your host adapter for detailed LED interpretations and actions.
Verify that the PCI-SCI host adapter card DIP switch settings are correct, as described in the documentation that came with your PCI-SCI host adapter.
Verify that the PCI-SCI cables are correctly connected so that the PCI-SCI cable connectors that are marked "SCI In" are connected to the "I" ports on the PCI-SCI adapter cards and to the "In" ports on the SCI switches (if you are using switches).
Verify that the cables are correctly connected so that the PCI-SCI cable connectors that are marked "SCI Out" are connected to the "O" ports on the PCI-SCI adapter cards and to the "Out" ports on the switches (if you are using switches).
Verify that the PCI-SCI switch Unit selectors are set to "F."
