10/100 Ethernet Management and HA Ports

Use modular, RJ-45, straight-through UTP cables to connect the 10/100 Fast Ethernet ports to end systems. Use modular, RJ-45 cross-connect cables to connect to external switches and routers. Figure B-1 shows straight-through cables and Figure B-2 shows cross-connect cables.

Figure B-1 Straight-Through Cables

Figure B-2 Cross-Connect Cables

The 10/100 Fast Ethernet ports support RJ-45 connectors. Table B-3 lists the signals for RJ-45 connector pinouts.
