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.

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.
Note 2
: For PoE High Power feeding purpose, JetNet4706/JetNet4706f should be wall
mounted on control panel to obtain great heat radiation.
Caution
: The PoE port of JetNet 4706/4706f should not make connection to Ethernet network
with outside plant routing includeing campus, due the lighting strike may damage the system
through the power system.
2.7 Wiring RS-232 Console Cable and pin assignment
Korenix
includes one RS-232 DB-9 to RJ-45 cable.
1. Connect the DB-9 connector to the serial communication port ( RS-232) of your PC
2. Open Terminal tool and set up serial settings to 9600, N, 8, 1. (Baud Rate: 9600 / Parity
Check: None / Data Bit: 8 / Stop Bit: 1) Then you can access the CLI interface through the
console cable.
Note: If you lose the cable, please contact your sales representative to purchase a new one.
The pin assignment spec is listed in the
Appendix
