Grounding the EtherDevice Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
This product is intended to be mounted to a well
-grounded
mounting surface such as a metal panel.
Wiring the Redundant Power Inputs
The two 2-contact terminal block connectors on the EDS’s top panel are
used for the EDS’s two DC power inputs. Top and front views of the
terminal block connectors are shown here.
STEP 1:
Insert the negative/positive DC wires into the V
-/V+
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.
Insert the plastic terminal block connector prongs into the
terminal block receptor, which is located on
the
Before connecting the EtherDevice Switch to the DC power
inputs,
make sure the DC power source voltage is stable and
the
DC power source is supplied by UL Listed Isolated Power Supply.
Communication Connections
The EDS-G205A-4PoE switches have 4 10/100/1000Base-T(X) PoE
Ethernet ports for connecting PoE devices, and 1 10/100/1000BaseT port
or 1 100/1000BaseX SFP slot for uplink connection. For fiber connections,
a field installed optical transceiver must be UL Recognized, in the Class I
category, and contain the following CDRH Certification Marking:
‘Complies with 21CFR 1040.10 and 1040.11’.
10/100/1000BaseT(X) Ethernet Port Connection
10/100/1000BaseT(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.
