straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable,
are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The
table below shows the 10BASE-T/ 100BASE-TX MDI and MDI-X port pin outs.
Pin MDI-X Signal Name MDI Signal Name
1 Receive Data plus (RD+) Transmit Data plus (TD+)
2 Receive Data minus (RD-) Transmit Data minus (TD-)
3 Transmit Data plus (TD+) Receive Data plus (RD+)
6 Transmit Data minus (TD-) Receive Data minus (RD-)
2 Gigabit Copper/SFP (mini-GBIC) combo port:
The PoE switch has the auto-detected Giga port—Gigabit Mini-GBIC/Copper 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. They are for connecting to the network
segment with single or multi-mode fiber. You can choose the appropriate SFP module
to plug into the slots. Then use proper multi-mode or single-mode fiber according to the
used SFP module. With fiber optic, it transmits at speed up to 1000 Mbps and you can
prevent noise interference from the system; the transmission distance depending on
the mini-GBIC module is up to 110 km.
