RJ-45 Port Pin Assignments
All LAN ports on the CheetahAccess Wireless Gateway support automatic MDI/
MDI-X configuration. This means that the pin signals in use will depend on whether
the LAN port is operating in MDI or MDI-X mode. However, the WAN port is
configured only for MDI-X mode.
Caution: DO NOT plug a phone jack connector into any RJ-45 port. For Ethernet
connections, use only twisted-pair cables with RJ-45 connectors that conform
with FCC standards.
