2.4 Network Connection
The EKI-7626C 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 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-7626C (MDI-X) to another hub or switch either MDI-X or uplink MDI port.
The EKI-7626C 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 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.
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.
