3.6 Cabling
 Use four twisted-pair, Category 5e or above cabling for RJ-45 port connection. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must
be less than 100 meters (328 ft.) long.
 Fiber segment using single-mode connector type must use 9/125 µm single-mode
fiber cable.
 Fiber segment using multi-mode connector type must use 50 or 62.5/125 µm multi-
mode fiber cable.
 Gigabit Copper/SFP (mini-GBIC) combo port:
The Industrial switch has the auto-detected Giga port—Gigabit Copper/SFP combo ports.
The Gigabit Copper (10/100/1000T) ports should use Category 5e or above UTP/STP
cable for the connection up to 1000Mbps. The small form-factor pluggable (SFP) is a
compact optical transceiver used in optical communications for both telecommunication
and data communications. The SFP slots supporting dual mode can switch the
connection speed between 100 and 1000Mbps. They are used for connecting to the
network segment with single or multi-mode fiber. You can choose the appropriate SFP
transceiver to plug into the slots. Then use proper multi-mode or single-mode fiber
according to the transceiver. With fiber optic, it transmits at speed up to 1000 Mbps and
you can prevent noise interference from the system.
Note The SFP/Copper Combo port can’t both work at the same time. The SFP port
has the higher priority than copper port; if you insert the 1000M SFP
transceiver (which has connected to the remote device via fiber cable) into the
SFP port, 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.
