“+” and “-” signs represent the polarity of the wires that make up each wire pair.
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
60825-1 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 2.7. Notice
that the triangle mark is at the bottom of the SFP slot. Figure 2.8 shows SFP transceiver
module was inserted.
