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.
RS-232 Management Port
The RS-232 management port is a male DB-9 receptacle. Data Terminal Ready (DTR) and Data Set Ready (DSR) handshake signals are supported by this port. Table B-4 lists the RS-232 management port pinouts.
