2-7. Connecting the Ethernet ports
The JetCon 2302 supports 2 10/100TX RJ-45 ports and 2 100Base-FX
fiber ports. The wiring methods for the RJ-45 and fiber ports are described
in this session. They also include the specifications of fiber port.
RJ-45 Fast Ethernet port
The RJ-45 port supports 10Base-T and 100Base-TX with Auto MDI/MDI-X
and auto negotiation features that allow users to connect with other devices
with straight through or cross-over cabling. It also supports speed
auto-negotiation for 10/100Mbps. The following diagram shows the straight
through and cross-over cablings.
The RJ-45 ports support auto-MDI/MDI-X function without any cable
change in case an Ethernet cable is used to connect other devices, such
as computers, switches or hubs.
Fast Ethernet Fiber port
The Fiber port supports IEEE 802.3u 100Base-FX standard for the single
mode or multi-mode type fiber cable with different link distances. For more
cable information, please refer to the product label stick on the rear side of
the device.
Before installing the fiber cable, please ensure that the cable type is matched
with the specifications of fiber transceiver. The following diagram shows how
to install fiber cable between 2 fiber ports. The RX must cross connect with
the remote device’s TX port, and TX port must
cross connect with remote
device’s RX port.
