• PORT1 and PORT2 need not to be distinguished. When only one connector is used in star topology, either
PORT1 or PORT2 can be connected.
• When two connectors are used in line topology or ring topology, an Ethernet cable can be connected to the
connectors in any combination. For example, the cable can be connected between PORT1s and between
PORT1 and PORT2.
• Connection between PORT1 and PORT1 or between PORT2 and PORT2
• Connection between PORT1 and PORT2
