Connect one side of an Ethernet cable into any switch port and connect the other side to your
attached device. The LINK LED will light up when the cable is correctly connected. Refer to
the LED Indicators section for descriptions of each LED indicator. Always make sure that the
cables between the switches and attached devices (e.g. switch, hub, or workstation) are less
than 100m (328 ft) apart.
The wiring cable types are as follows:
10Base-T: 2-pair UTP/STP Cat. 3, 5e, 6 cable, EIA/TIA-568-B.2 100-ohm (up to 100m)
100Base-TX: 2-pair UTP/STP Cat. 5e, 6 cable, EIA/TIA-568-B.2 100-ohm (up to 100m)
2.6 Connecting Powered Device (PD)
JetNet 4706/4706f is equipped with 4-Port PoE injectors which are in compliance with IEEE
802.3af standards for 15.4w forwarding capability and IEEE 802.3at pre-standard for high
power. The powering architecture of JetNet 4706/4706f follows IEEE 802.3af Alternative B
mode standards of conductor assignment.The following table shows the pin assignment of
alternative A and B for the PSE (Power Source Equipment).

(MDI-X) Alternative A (MDI) Alternative B (All)
1 RX & Negative Vport Tx & Positive Vport
2 RX & Negative Vport TX & Positive Vport
3 TX & Positive Vport RX & Negative port
4 Positive Vport
5 Positive Vport
6 TX & Positive Vport RX & Negative Vport
7 Negative Vport

JetNet 4706/4706f Industrial Managed PoE Switch 8
8 Negative Vport
Make sure the twisted pair cable is bound with the standard RJ-45 pin, especially pins 4, 5, 7
and 8.
If the RJ-45 is bound with the wrong pin number, JetNet 4706/4706f will
not recognize the PD and will not forward DC power to the PD. This is
because the JetNet 4706/4706f switch follows the Alternative B mode.
The IEEE 802.3af indicates that the PD should support mode A and B,
but only receive power from either mode A or B.
The following table shows the RJ-45 pin out for the PD.
PD Pin out
Conductor Mode A Mode B
1 Positive Vport, Negative Vport
2 Positive Vport, Negative Vport
3 Negative Vport,Positive Vport
4 Positive Vport, Negative Vport
5 Positive Vport, Negative Vport
6 Negative Vport,Positive Vport
7 Negative Vport,Positive Vport
8 Negative Vport,Positive Vport
Note 1: Before installing the Powered Device (PD), please ensure the PD pin assignment
follows the IEEE 802.3af PD standards. There are some IEEE 802.3af pre-standard PDs that
only accept mode A for power. IEEE 802.3af indicates that the PD should be powered by
either Mode A or B.
