CHAPTER 1. DESCRIPTION
1.1. Introduction
Using Ethernet networking in the manufacturing
environment can enhance information flow, improve
maintainability, and simplify access for better monitoring
and diagnostics. However, the unique challenges of
operating in harsh environments demand network
components which are designed especially for industrial
installations.
The 3570 Series of 5-port Industrial Ethernet Switches
from CTI is designed specifically for providing network
access to small clusters of factory floor equipment. In
addition to its ability to withstand harsh production
requirements, the 3570 Series includes features like
spacesaver DIN rail mounting and redundant power
supply connection which make it even easier to integrate
into a typical industrial installation.
Features
• Five Ethernet ports, available in four different
configurations of copper and fiber media
• Isolated power supply
• 10/100 Mbps with auto-negotiation, auto-
crossover and auto-sensing on all RJ45 ports
Figure 1. 3570 Front Panel
1.2. Power Supply
The 3570 requires an external power supply for operation. For use in high-availability applications, it
includes provision for connecting dual redundant power supplies. An isolation barrier is designed
onboard the 3570 for isolating the input supply from the switching circuitry, and the incoming power is
fused. This reduces the chance of damaging the 3570 circuitry from power surges occurring on external
power lines.
The input power specification is: 11-32VDC
Power is connected to the 3570 using the connector at the top of the case.

1.3. Ethernet Ports
All 3570 Series Ethernet switches provide five ports for
Ethernet connection. Depending on the model switch you
have, the switch has a combination of RJ45 (twisted pair) and
MTRJ (fiber) connectors:
3570-5C 5 RJ45 ports
3570-1F 4 RJ45, 1 MTRJ
3570-2F 3 RJ45, 2 MTRJ
3570-3F 2 RJ45, 3 MTRJ
All ports are IEEE802.3 compliant, and RJ45 ports include
auto-negotiation, auto-sensing, and auto-crossover. This
allows connection of any Ethernet device without worrying
about speed, cable rollover, or full/half duplex. The switch
automatically detects the characteristics of the attached
device/cable and sets up its port accordingly.
1.4. LED Indicators
Figure 2. RJ45 Ethernet Ports on 3570-5C
All 3570 Series Ethernet switches provide LED indication of major functions to assist in installation and
troubleshooting.
POWER LEDs – P1 and P2 LEDs are lighted when power inputs P1 and P2 are above the minimum
threshold voltage.
LINK/ACT LEDs (1 per port)
OFF - nothing is connected to the port (no link beat)
ON – there is a good connection to a device, but no data is being transmitted or received
FLASHING - a good connection exists and data is being transmitted
10/100 LEDs (1 per port)
OFF - connection is 10Mbit/s
ON – connection is 100Mbit/s

CHAPTER 2. INSTALLATION
The installation of the 3570 Ethernet switch consists of the following steps:
1) Unpacking
2) Mounting on the DIN rail
3) Connecting power
4) Connecting network cables
5) Checkout
2.1. Unpacking
Open the shipping carton and remove the special anti-static bag that contains the 3570. After discharging
any static build-up, remove the module from the static bag. Do not discard the static bag. Always use
this bag for protection against static damage when the module is not inserted into the I/O base.
CAUTION:
The components on the 3570 printed circuit card can be damaged by static electricity discharge. To
prevent this damage, the module is shipped in a special anti-static bag. Static control precautions
should be followed when removing the module from the bag and when handling the printed circuit
card during configuration.
2.2. Mounting on the DIN rail
The 3570 is designed for DIN rail mounting. To install, simply engage the top of the rail in the top
channel of the 3570, then rotate the unit downward until it snaps into place.
To remove the unit, insert a screwdriver into the red tab and pry the tab outward until the lock in
released, then rotate the unit upward and lift off.

rail

DIN rail

2.3. Connecting Power
The 3570 requires an external 11-32VDC power supply (300mA) for operation. For high-availability
applications, it supports the connection of two independent power supplies in a redundant configuration.
If one supply fails, the switch will draw power from the other supply to continue operating.
The external supply is connected using the removable screw-terminal connector located at the top of the
switch.
If the 3570 is being connected in a single-supply configuration, attach the ‘+’ and ‘-‘ terminals from the
power supply to the P1+ and P1- connectors. For a dual supply, attach the second power supply at
P2+ and P2-.
The power connector terminal labeled “CHASSIS GND” should be connected to a convenient earth
ground on the panel.
2.4. Connecting Network Cables
Connecting to the RJ45 Ports
Insert the RJ45 plug on your twisted pair cable into an RJ45
jack on the 3570. Push the plug into the jack until the plug
clicks into place. To remove the plug, simply depress the
latching tab and pull the plug out of the jack.
Connecting to the MTRJ Port(s)
Insert the MTRJ plug on your fiber cable into an MTRJ jack
on the 3570. Push the plug into the jack until the plug clicks
into place. To remove the plug, simply depress the latching
tab and pull the plug out of the jack.

2.5. Checkout
Once power is applied and network cables are attached, checkout of the 3570 requires only 4 steps:
1. Verify P1 LED is ‘ON’
2. Verify P2 LED is ‘ON’ if a second power supply is connected
3. Verify LINK/ACT LEDs are on or blinking for ports connected to active devices
4. Verify 10/100 LEDs are ‘ON’ for ports connected to 100Mbit devices

CHAPTER 3. TROUBLESHOOTING
If you experience a problem in communicating with the module, consider the following troubleshooting
guidelines:
1. Check the P1 and P2 LEDs on the front of the 3570. If one or both of these is not ON, the
module is not receiving power.
2. Verify the voltages at the power supply input connector at the top of the module. P1 and P2
(optional) voltages should be 11-32VDC.
3. If the voltage(s) are good and both power LEDs are off, the internal fuse and blown and the unit
must be returned to CTI for repair.
4. Verify continuity of Ethernet fiber or copper cables. Plug a known good device and cable into each
of the ports and make sure the LINK/ACT light for that port comes on.
