Wiring the Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies the IEX-402-SHDSL with power.
The two 2-contact terminal block connectors on the IEX's top panel are
used for IEX's two DC power inputs. Top and front view of the terminal
block connectors are shown here.
Step 1:
Insert the negative/positive DC wires into the
V
-/V+ terminals
Step 2:
To keep the DC wires from pulling loose, use a
small flat
-blade screwdriver to tighten the wire-clamp
screws on the front of the terminal block connector.
Step 3:
Insert the plastic terminal block connector
prongs into the terminal block receptor, which is located
on IEX’s top panel.
ATTENTION
Before connecting the IEX
-402-SHDSL to the DC power inputs,
make sure the DC power source voltage is stable.
Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the
IEX-402-SHDSL’s 10/100BaseTX ports to any kind of Ethernet device,
without needing to pay attention to the type of Ethernet cable being used
for the connection. This means that you can use either a straight-through
cable or cross-over cable to connect the IEX-402-SHDSL to Ethernet
devices.
Communication Connections
IEX-402-SHDSL models have one 10/100BaseT(x) Ethernet port, and one
DSL port.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the IEX’s front panel are used to
connect to Ethernet-enabled devices.
Next, 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.
