2.4 Network
Connection
The EKI-2748FI has 4 x RJ-45 ports that support connection to 10 Mbps Ethernet, 100
Mbps Fast Ethernet or 1000 Mbps Gigabit Ethernet. EKI-2748FI 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-2748FI (MDI-X)
to another hub or switch either MDI-X or uplink MDI port.
The EKI-2748FI 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-2748FI has 4 SFP slots for connecting to the network segment with single or multi-
mode fiber. You can choose appropriate mini-GBIC transceivers to plug into the slot.
Make sure the slot is aligned correctly and then slide the transceiver into the SFP slot
until a click is heard. You can use proper multi-mode or single-mode fiber according to
the inserted SFP transceiver. 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 transceivers.
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. Note that the location of the triangle
indicates the bottom of the slot.
