2.4 Network Connection
The EKI-7626C/7626CI 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-7626C/7626CI 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-7626C/7626CI (MDI-X) to another hub or switch either MDI-X or uplink
MDI port.
The EKI-7626C/7626CI 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-7626C/7626CI 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 1,000 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.
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 module. Note that the location of the triangle indicates the
bottom of the module.
