ATTENTION
Before connecting the EtherDevice Switch to the DC power
inputs, make sure the DC power source voltage is stable.
Communication Connections
The EDS-P206A-4PoE switches have 6, 7, or 8 10/100BaseT(X) Ethernet
ports, and 2, 1, or 0 (zero) 100BaseFX multi/single-mode (SC/ST-type
connector) fiber ports.
10/100BaseT(X) Ethernet Port Connection
10/100BaseT(X) ports located on the EDS’s front panel are used to
connect to Ethernet-enabled devices. Below we show pinouts for both
MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports, and also show
cable wiring diagrams for straight-through and cross-over Ethernet
cables.

PoE 10/100BaseT(X) Ethernet Port Connection
PoE 10/100BaseT(X) ports located on the EDS switch’s front panel are
used to connect to PoE-enabled devices. The pinout follows the
Alternative A, MDI-X mode” of 802.3af/at standards. Please see the
details in the following table.

NOTE
According to IEEE 802.3af/at standards, the PD shall be
implemented to be insensitive to the polarity of the power supply
and shall be able
to operate per MDI mode and MDI-X mode.
However, some PD
s only support MDI mode or MDI-
X mode only.
The following
figure shows how to select the correct cable
between the PD and EDS-P206A-4POE.
