Overview
This series is rated IP30 and installation by DIN Rail. Each unit of this industrial gigabit managed
Ethernet switch series has 8 10/100/1000Tx Gigabit Ethernet ports and 2 dual-rate (100/1000) SFP
slots, suitable for applications that require high bandwidth and long distance communication.
In order to prevent unregulated voltage, this series provides high EFT and ESD protection. This also
allows it to function in harsh environments, as well as support power redundancy with a dual power
input design with reverse polarity protection. The built-in relay warning function alerts users about
occurring power failures.
With one model having an operating temperature of , and another with a wide operating temperature
of -40°C ~ 75°C, this series is designed to meet any needs for industrial automation, outdoor
application and harsh environments.

Ethernet Ports
RJ-45 Ports(Auto MDI/MDIX)
The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or 1000Base-T devices connections. Auto
MDI/MDIX means that the switch can connect to another switch or workstation without changing the
straight-through or crossover cabling. See the figures as below for straight-through and crossover
cabling schematics.
RJ-45 Pin Assignments (Table 2.2)
Table 2.2: RJ-45 Pin Assignments
Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
All ports on this industrial Ethernet switch support automatic MDI/MDI-X operation. Users can use
straight-through cables (see Figure 2.4) for all network connections to PCs, servers, other switches or
hubs. With straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight
through to pins 1, 2, 3 and 6 at the other end of the cable. The table below (Table 2.3) shows the
10BASE-T, 100BASE-TX, 1000BASE-TX MDI and MDI-X port pin outs.
Table 2.3: Ethernet Signal Pin Outs
The following figures show the cabling schematics for straight-through and crossover.

The following figures show the 10,100, and 1000 Ethernet RJ-45 pin outs.
Figure 2.6: RJ45 Ethernet Port Pin Outs
Figure 2.7: Straight-Through Cable Schematic
Figure 2.8: Crossover Cable Schematic
Cabling
Use the four twisted-pair, category 5e, or the above cabling for RJ-45 port connections. The cable
between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100 meters
(328 ft.) long.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications
for both telecommunication and data communication applications.

To connect the transceiver and LC cable, please follow below steps:
Step 1. Insert the SFP transceiver module into the SFP slot as shown below in Figure 2.9. Notice that
the triangle mark is at the bottom of the SFP slot. Figure 2.10 shows SFP transceiver module
was inserted.
Figure 2.9: Transceiver to the SFP Module
Figure 2.10: Transceiver Inserted
Step 2. Insert the fiber cable of the LC connector into the transceiver as shown below in Figure 2.11.
Figure 2.11: LC Connector to the Transceiver

To remove the LC connector from the transceiver, please follow the steps shown below:
Step 1. Press the upper side of the LC connector from the transceiver and pull it out to release as
shown below in Figure 2.12
Figure 2.12: Remove LC Connector
Step 2. Push down the metal clasp and pull the transceiver out by the plastic part as shown below in
Figure 2.13
Figure 2.13: Pull Out from the SFP Module

Wiring the Power Inputs
Please follow the below steps to insert the power wire.
Step 1. Insert the positive and negative wires into the PWR1 (V1+, V1-) and PWR2 (V2+, V2-) contacts
on the terminal block connector as shown below in Figure 2.14.
Figure 2.14: Power Terminal Block
Step 2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure
2.15.
Figure 2.15: Power Terminal Block
Note:
Only use copper conductors, 60/75°C, tighten to 5 lbs.
The wire gauge for the terminal block should range between 18~20 AWG.

barox Kommunikation
12
Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows below in
Figure 2.16. By inserting the wires, it will detect the fault status including power failure or port link
failure (managed industrial switch only) and form a normally open circuit. An application example for
the fault alarm contact is shown below in Figure 2.16.
Figure 2.16: Wiring the Fault Alarm Contact
Note:
The wire gauge for the terminal block should range between 12 ~ 24 AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to eliminate power
fault alarm.
