Straight-Through Cabling Schematic
Crossover Cabling Schematic
Note:
The Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ-45 connector. The signals of
these pins are converted by the automatic MDI-X function, as shown in the table below:

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)
