2.4 Network Connection

The EKI-7659CPI 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-7659CPI 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-

7659CPI (MDI-X) to another hub or switch either MDI-X or uplink MDI port.

The EKI-7659CPI 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-7659CPI 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.

Note

The SFP/Copper Combo port can be used at one time either. 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. Notice that the triangle mark is the

bottom of the module.
