INSTALLATION AND OPERATION MANUAL
CNGE2FE16MS
TECh SUPPORT: 1.888.678.9427
Gigabit Copper/SFP Combo Port
The CNGE2FE16MS is equipped with Gigabit Copper/SFP combo ports. The Gigabit Copper
(10/100/1000T) ports should use Category 5e or above UTP/STP cable for the connection speed
up to 1000Mbps. SFP slots supporting dual mode to toggle the connection speed between 100
and 1000Mbps are used for connecting to the network segment with single or multi-mode fiber
optics. You can choose the appropriate SFP transceiver to plug into the SFP socket with proper
multi-mode or single-mode fiber cable according to that transceiver.
Note
The particular SFP/Copper Combo port is deemed to be a single port that either the SFP or
Copper port operates; the SFP and Copper ports cannot both operate at the same time.
The SFP port has the higher priority than the corresponding copper port; if you insert the
1000M
SFP transceiver (which has connected a fiber cable between that transceiver and the
remote node) into the SFP port, the connection of the corresponding copper port will link
down.
If you insert the
100M
SFP transceiver into the SFP port even without a fiber cable between
that transceiver and the remote node, the connection of the corresponding copper port will
link down immediately.
