8. Wiring Redundant Power Inputs and Power Fault
Relay
The switch supports redundant power supplies and provides a power fault relay which
can be used for alarming in case of interruption of Power 1 or Power 2. For wiring via 6-
pin terminal connector please refer to below illustration.
Warning / Avertissement
Take into consideration the following guidelines before wiring the
device
oTenez compte des directrices suivantes avant de câbler l’appareil.
Terminal block is mating with Plug and suitable for 12-24AWG.
Torque value 4.5 lb-in.
oLe bornier est compatible avec les connecteurs et convient pour 12-
24AWG. Valeur de couple 4,5 lb-in.
The temperature rating of the input connection cable should higher
than 105°C.
oLa température de service nominale du câble d’entrée doit être
supérieure à 105 °C.
Use Copper Conductors Only.
oUtilisez uniquement des conducteurs en cuivre.
Supplied by SELV or double insulation source evaluated by UL
61010-1 or 61010-2-201 power supply only.
oFourni par la source SELV ou double isolation évaluée uniquement
par l'alimentation UL 61010-1 or 61010-2-201.
Note about behavior of power failure relay:
Relay contact is closed if the device is powered-off.
Relay contact always is open if the device is powered either by PWR1 or PWR2 and
if DIP switches 1 and 2 for power control are set to off.
Relay contact closes if DIP switch 1 is set to ON and PWR1 fails.
Relay contact closes if DIP switch 2 is set to ON and PWR2 fails.
9. Communication Connections
Switch IE-SW-EL08-8GTPoE is equipped with the following communication interfaces:
8 x 10/100/1000Base-T PoE ports (P.S.E.)
9.1 10/100/1000Base-T(X) PoE ports (P.S.E)
For communication without PoE sourcing the switch supports auto negotiation speed,
Full/Half duplex mode and auto MDI/MDI-X connection, means automatic setting of
pinouts for both MDI ports (NIC-type) or MDI-X ports (HUB/Switch-type).
In case of active PoE sourcing the switch uses the pinout of “Alternative A, MDI mode” of
802.3af/802.3at 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 PDs only support MDI mode or MDI-X mode only.
If the PD only supports PoE MDI mode (V+, V+, V-, V- for pins 1, 2, 3, 6), choose a
cross-over Ethernet cable to connect the PD and the switch. If the PD only supports PoE
MDI-X mode (V-, V-, V+, V+ for pins 1, 2, 3, 6), choose a straight-through Ethernet cable
between the PD and the Switch.
Total PoE Budget
For the total PoE power budget, the switch will provide 60 Watts from 12 to 23 VDC input
voltage and 120 Watts from 24 to 57 VDC input voltage. The total power budget is the
total amount of reserved PoE power based on the PoE class of the PoE device. If a
newly connected PoE device causes the total reserved power to exceed the total power
budget, the newly connected PoE device will be denied power.
10. LED Indicators
The front panel of the Ethernet Switch contains several LED indicators. The function of
each LED is described in the table below.
LED Color Status Description
PWR1 Green
On Power is being supplied to power input
PWR1.
Off Power is not being supplied to power input
PWR1.
PWR2 Green

FAULT Amber
On Indicates PWR1 or PWR2 fault (if
corresponding DIP switches are set to ON).
Off If DIP switches are set to OFF or no power
failure.
