EKI-7758F User Manual 18
2.4 Network Connection
The EKI-7758F has 4 x RJ-45 ports that support connection to 10 Mbps Ethernet, 100
Mbps Fast Ethernet or 1000 Mbps Gigabit Ethernet. EKI-7758F can be connected to
other hubs or switches through a twisted-pair straight cable or a crossover cable up to
100m long. The connection can be made from any TX port of the EKI-7758F (MDI-X)
to another hub or switch either MDI-X or uplink MDI port.
The EKI-7758F 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-7758F has 4 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.
