FAULT: The two middle contacts of the 6-
contact
terminal block connector are used to
de tect both power faults and port faults. The
two wires attached to the
fault c on tac ts
form
a
n open circuit when:
A relay warning event is triggered.
OR
T
he EDS-405A/408A is the Master of this
Turbo Ring, and the Turbo Ring
is broken.
OR
There is a s
tart-up failure.
If
none of these three conditions is satisfied,
the fault circuit will re m ain closed.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on the EDS-405A/408A’s top panel are used
for the EDS-405A/408A’s two DC inputs. Top and front views of one of
the terminal block connectors are shown in the following figures:
STEP 1: Insert the negative/positive DC
wires into the
V-/V+ terminals, respectively.
STEP 2:
To keep the DC wires from pulling
loose, use a sm all flat
-blade screwdriver to
tighten the wire
-
clamp screws on the front of
the terminal block connector.
STEP 3:
Inse rt the plastic terminal block
connector prongs into the terminal block
rece ptor, which is
located on the EDS-
405A/408A’s top panel.
ATTENTION
Be fo re connecting
the EDS-405A/4 0 8A
to the DC power inputs,
m ake sure the DC power source voltage is stable.
Communication Connections
EDS-408A models have 5, 6, or 8 10/100BaseT(X) Ethernet ports, and
3, 2, or 0 (zero) 100BaseFX (SC/ST-type connector) fiber ports. EDS-
405A models have 3 or 5 10/100BaseT(X) Ethernet ports, and 2 or 0
(zero) 100 BaseFX (SC/ST-type connector) fiber ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS’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.
