2.4 Network Connection
The EKI-7659C has 8 x RJ-45 ports that support connection to 10 Mbps Ethernet, or
100 Mbps Fast Ethernet, and half or full duplex operation. EKI-7659C can be
connected to other hubs or switches through a twisted-pair straight through the cable
or a crossover cable up to 100m long. The connection can be made from any TX port
of the EKI-7659C (MDI-X) to another hub or switch either MDI-X or uplink MDI port.
The EKI-7659C supports auto-crossover to make networking more easy and flexible.
You can connect any RJ-45 (MDI-X) station port on the switch to any device such as a
switch, bridge or router.
2.5 Connection to a Fiber Optic Network
EKI-7659C has two SFP slots for connecting to the network segment with single or
multi-mode fiber. You can choose appropriate mini-GBIC module to plug into the slot.
Make sure the module is aligned correctly and then slide the module into the SFP slot
until a click is heard. You can use proper multi-mode or single-mode fiber according to
the used SFP module. With fiber optic, it transmits speed up to 1000 Mbps and you
can prevent noise interference from the system and transmission distance up to 110
km, depending on the mini-GBIC module.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communications applications.
To connect the transceiver and LC cable, please follow the steps shown below:
First, insert the transceiver into the SFP module. Notice that the triangle mark is the
bottom of the module.
