2.4 Network
Connection
The EKI-7656C/7656CI has 16 x RJ-45 ports that support connection to 10 Mbps
Ethernet, or 100 Mbps Fast Ethernet, and half or full duplex operation. EKI-
7656C/7656CI can be connected to other hubs or switches via a twisted-pair straight-
through or crossover cable up to 100m long. The connection can be made from any TX
port of the EKI-7656C/7656CI (MDI-X) to another hub or switch either MDI-X or uplink
MDI port.
The EKI-7656C/7656CI 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-7656C/7656CI has two SFP slots for connecting to the network segment with
single- or multi-mode fiber. You can choose the appropriate mini-GBIC transceiver to
plug into the slot. Make sure the transceiver is aligned correctly and then slide it into
the SFP slot until a click is heard. You can use proper multi-mode or single-mode fiber
according to the connected SFP transceiver. With fiber optic, it transmits speed up to
1000 Mbps that you can prevent noise interference from the system and transmission
distance up to 110 km, depending on the mini-GBIC transceiver.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communications applications.
Note
The SFP/Copper Combo port can’t be used at the same time. The SFP port has the
higher priority than copper port; if you insert the 1000M SFP transceiver into the SFP port
which is connected to the remote device, the connection of the accompanying copper
port will link down.
If you insert the 100M SFP transceiver into the SFP port even without a fiber connection
to the remote, the connection of the accompanying copper port will link down
immediately.
To connect the transceiver and LC cable, please follow the steps shown below:
First, insert the transceiver into the SFP slot. Notice that the triangle mark indicates the
bottom of the slot.
