Connector Pinouts

This appendix lists the pinouts of the connectors used to connect the port adapters to an external network. All pins not specifically listed are not connected.

For processor card cable pinouts, see the appendix "Processor Card Cabling Specifications" in the Processor Installation Guide for your system.

This appendix lists the following signal summaries:

Pinouts to RJ-45 Connectors

The 155-Mbps port adapter with unshielded twisted-pair (UTP) ports supports RJ-45 connectors. Table B-1 lists the signals for RJ-45 cable connectors.
