connected with the protective earth.
To ensure the system will not be damaged by noise or any electrical shock, we suggest making
a direct connection with
JetNet 3706/JetNet 3706f
and Earth Ground to avoid system damage
from electrical static discharge.
On the right-side of
JetNet 3706/JetNet 3706f ,
there is one earth ground screw. Loosen the
earth ground screw with a screwdriver and tighten the screw after the earth ground wire is
connected.
2.4 Wiring Fast Ethernet Ports
JetNet 3706/JetNet 3706f
is equipped 4 Power over Ethernet (PoE ) injectors with 30w
forwarding capability in ports 1~4. The fast Ethernet ports support 10Base-T and 100Base-TX,
full or half duplex modes. All of the fast Ethernet ports auto-detect signals from connected
devices to negotiate link speed and duplex mode. Auto MDI/MDIX allows users to connect to
another switch, hub or workstation without changing straight-through or crossover cables.
JetNet 3706f
has 2 100Mbps fiber ports for multi-mode or single-mode fiber.
Note that crossover cables simply cross-connect the transmit lines at each end to the received
lines at the opposite end.

Note 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 end of an Ethernet cable into any switch port and connect the other end to your
attached device. The LINK LED will light up when the cable is connected correctly. Refer to the
LED Indicators
section for descriptions of each LED indicator. Always make sure that the
cables connecting the switch and all attached devices (e.g. switch, hub, or workstation) are less
than 100 meters (328 feet).
The wiring cable types are as follows:
10Base-T: 4 Pair UTP/STP Cat 3, 5e, 6 cable, EIA/TIA-568-B.2 100-ohm (up to100m)
100Base-TX: 4 Pair UTP/STP Cat. 5e, 6 cable, EIA/TIA-568-B.2 100-ohm (up to 100m)
