Cabling
Use the four twisted-pair, category 5e, or the above cabling for RJ-45 port
connections. The cable between the Switch and the link partner (switch, hub,
workstation, etc.) must be less than 100 meters (328 ft.) long.
The small form-factor pluggable (SFP) is a compact optical transceiver used in
optical communications for both telecommunication and data communication
applications.
Caution: Please employ optional optical transceiver (SFP/Fixed Fiber)
that complies with IEC 608251 and classified as Class 1 laser product.
To connect the transceiver and LC cable, please follow below steps:
Step 1. Insert the SFP transceiver module into the SFP slot as shown
below in Figure 2.4. Notice that the triangle mark is at the bottom of the SFP
slot. Figure 2.5 shows SFP transceiver module was inserted. 
Step 2. Insert the fiber cable of the LC connector into the transceiver as shown below in Figure 2.6.
To remove the LC connector from the transceiver, please follow the steps shown
below:
Step 1. Press the upper side of the LC connector from the transceiver and pull
it out to release as shown below in Figure 2.7 
Step 2. Push down the metal clasp and pull the transceiver out by the
plastic part as shown below in Figure
Wiring the Power Inputs
Caution: Please follow the below steps to insert the power wire.
Step 1. Insert the positive and negative wires into the PWR1 (V1+, V1-)
and PWR2 (V2+, V2-) contacts on the terminal block connector as shown below in
Figure 2.9. 
Step 2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.10.
Caution: Only use copper conductors, 125°C, tighten to 7 in-lbs (0.79 Nm). The wire gauge for the terminal block should range between 18~20 AWG.
Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as
the picture shows below in Figure 2.11. By inserting the wires, it will detect
the fault status including power failure or port link failure (managed
industrial switch only) and form a normally open circuit. An application
example for the fault alarm contact is shown below in Figure 2.11. 
Caution: The wire gauge for the terminal block should range between 12 ~
24 AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to
eliminate power fault alarm.
Grounding Note
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the ground
screw to the grounding surface prior to connecting devices. The grounding
screw symbol is shown blow in Figure 2.12.
Caution: Using a shielded cable achieves better electromagnetic compatibility.
