3.2.14 10BASE-T/100BASE-TX Interface Cable (CAT.5, RJ45 connector)
The boundary with 10BASE-T and 100BASE-TX is the connector on GS4000.
For the connection with 100BASE-TX, use a UTP interface cable categorized as “Category 5”.
(It is possible to use a UTP interface cable categorized “Category 3” for the connection only
with 10BASE-T.)
The maximum transmission distance for the connection of GS4000 with 10BASE-T or
100BASE-TX is 100m.
Figure 3.2-16/3.2-17 below show the rough sketch of the cables, and Table 3.2-22 shows the
pin arrangement on NE100-48T.

Pin number Specification
1 Receiving (+) (A)
2 Receiving (-) (a)
3 Sending (+) (B)
4 Unused (Note 1) (C)
5 Unused (Note 1) (c)
6 Sending (-) (b)
7 Unused (Note 1) (D)
8 Unused (Note 1) (d)
Note 1: This should be connected to the port when using 100BASE
-
TX. It is possible to choose “connection” or
“disconnection” when using the 10BASE-T.
Note 2: Because the interface uses differential, twisted pairs of wires, make (A) and (a), (B) and (b), (C) and (c), and (D)
and (d) into pairs when using 100BASE-TX, and make (A) and (a), and (B) and (b) into pairs when using the 10BASE-T.
For the interfaces other than those, you can choose “disconnection” or “connection” ignoring the combination of pairs.
