Aside from 2 Gigabit fiber optic/copper combo ports, the EKI-7626C comes equipped with 16 x 10/100Base-T(X) fast Ethernet ports and the EKI-7629C comes equipped with 8 x 10/100Base-TX fast Ethernet ports. Traditional RJ-45 ports can be used for uplinking wide-band paths in short distance (< 100 m), or the appropriate replaceable SFP module can be used for the application of wideband uploading and long distance transmissions to fit the field request flexibly. Also, the long MTBF (Mean Time Between Failures) ensures that the EKI-7626C/7629C will continue to operate until a Gigabit network infrastructure has been established, without requiring any extra upgrade costs. EKI-7626C/7629C includes a switch controller that can automatically sense transmission speeds (10/100Mbps) The RJ-45 interface can also be auto-detected, so MDI or MDI-X is automatically selected and a cross-over cable is not required. All Ethernet ports have memory buffers that support the store-and-forward mechanism, which assures that data can betransmitted properly. Furthermore, the power line of EKI-7626C/7629C supports up to 3,000 VDC surge (EFT) protection, which secure equipment against unregulated voltage and make systems safer and more reliable.
