Description
Intended for Multidrop Self-Healing Ring (SHR) topologies, the TC3720 Ethernet Fiber Optic Switch interconnects up to six 10/100M devices at each drop. The ring can consist of either multimode or single mode fibers or CAT5 UTP cables. Fault recovery time is less than 250 milliseconds.
The TC3720 offers a sophisticated Self-Healing Ring scheme. Fault conditions are detected on both Tx and Rx, upstream and downstream of each unit, and automatically re-routed to maintain Ring integrity.
A Web-based configuration user interface is provided to view and change network settings such as IP Address, Subnet, Gateway, Speed, Half/Full Duplex, Name, Password and other parameters. It also monitors the fiber ring status, alarm conditions, fault locations for local and remote units. The TC3720 can also be configured through a serial console (Out-of-Band).
The TC3720’s store-forward switching technology eliminates the congestion problem inherent to the contention-oriented Ethernet CSMA/CD protocol. This improves predictable response times under heavy network loads. Previously, expensive routing technology was used to alleviate congestion from heavy traffic loads.
The TC3720 offers two multimode (1300nm) or single mode (1300/1550nm) ports and six independent Ethernet 10/100-Base Auto-Sensing switched ports. As options, there are two versions (Model TC3720T) for extreme temperature applications (-20° to 70°C, -40° to 80°C).
Power is 12VDC, optional 24VDC, -48VDC, 125VDC or 115/230VAC. Power redundancy is standard on 12VDC. The unit is 19" rack mountable. Optical connectors can be ST, FC or SC.

User's Manual
Unpacking the Unit
Before unpacking any equipment, inspect all shipping containers for evidence of external damage caused during transportation. The equipment should also be inspected for damage after it is removed from the container(s). Claims concerning shipping damage should be made directly to the pertinent shipping agencies. Any discrepancies should be reported immediately to the Customer Service Department at TC Communi­cations, Inc.
Equipment Location
The TC3720 should be located in an area that provides adequate light, work space and ventilation. Avoid locating it next to any equipment that may produce electrical interference or strong magnetic fields, such as elevator shafts and heavy duty power supplies. As with any electronic equipment, keep the unit from excessive moisture, heat, vibration and freezing temperatures.
Dry Contact Alarm Relay
Two terminal block connectors on the rear panel (labeled "ALM RLY1," & "ALM RLY2") provide for the dry contact relay alarm (see Figure 2). Normally in the OPEN position, any loss of optical signal will trigger an alarm condition and force the switch to the CLOSED position. This relay can be used in conjunction with an external device to monitor the condition of the fiber optic links.

Rev. 1.5
Power Supply
Standard input power is 12V DC @500mA for the TC3720. The power plug is a terminal block connector with positive & negative polarity indicated on the rear panel of the unit. Two connectors, labeled "PWR A" & "PWR B" are provided for a built-in power redundancy feature. While only one connection is required to power the unit, both connectors can be used simultaneously. When power redundancy is utilized, both power "A" & "B" share the load. If one power supply fails, the other will take over the full load. Alternate power sources are available as an option (see Chapter 7 - Specifications).
Should an external power adapter need to be replaced, use one with the following specifications: 12V DC @500mA. You may order it directly from TC Communications.
Power Up Test:
Apply power by plugging the power plug into any power jack on the rear panel. After the power is applied, the following LED status should be observed from the front panel.
After power up, if no LEDs are lit, refer to Chapter 6 (Troubleshooting).
1. The "PWR A" or "PWR B" LEDs on the front panel will light according to which power jack (A or B)
is connected. Both LEDs will light when power redundancy is utilized.
2. Both "Vcc1" and "Vcc2" LEDs should be solidly lit, indicating an adequate operating voltage is being
derived from the power source.
3. The "100M" & "FULL/COL" LEDs for both F1 and F2 should be solidly lit. The "LINK/ACT" LED
should be Off since there is no Ethernet or optical activity.
4. The "ALARM," "F1/1X," and "F2/2X" LEDs should be flashing indicating that there is no fiber optic
cables connected.
Note: On power up, if the self-healing function is disabled with front panel dip switch #1 in the "Up" position,
the "ALARM" LED will flash and the "F1/1X," and "F2/2X" LEDs will be off. All other LEDs will behave as indicated above.

To install the TC3720 units, you must first configure them for your specific application (for example, the setup on figure 4). Regardless of how the units are configured, each unit in the ring must have a unique Self Healing Ring (SHR) ID.
There are two ways to configure the TC3720's to be installed in the SHR setup. By hardware configurations or software configurations.
A. Hardware configurations : If the units are configured using hardware configurations with the DIP
switches on the rear panel, there is a limit to the SHR ID hardware settings. The maximum number of SHR ID's that can be used are 128 (see Appendix B), therefore the SHR can be connected with a maximum of 128 units when hardware settings are used. (Generally, hardware configurations are used when bench testing the units). See Chapter 3 (Hardware Configuration).
Note: Software configurations will overwrite the hardware settings for SHR ID and for Master/Slave (refer to chapter 4 for software configurations). The reset button on the rear panel can be used to return the unit to the current hardware settings.
B. Software Configurations : The units are configured through the Management port (RJ-45 connector
on the rear panel of the switches). See Chapter 4 (Software Configuration).
Note: If you want to configure the IP address, username, or password, you can also use the Console port (DB9 connector on the rear panel). Refer to console port settings on page 26.

Using the TC3720's as Regular Optical Switches (SHR Disabled)
The TC3720 units can be used as regular optical switches by disabling the self-healing ring function. They can be used for point to point applications using either fiber port 1 (F1) or fiber port 2 (F2). For example, as shown on the diagram below.
To set the TC3720's as regular optical switches, simply set the front panel DIP switch #1 (SHR) to the up "Off" position. Refer to dip switches on figure 1.

Self Healing Ring (SHR) ID Setting
The Self Healing Ring (SHR) can be connected with a maximum of 128 units. The ID setting can be configured with either hardware or software (each unit must have a unique ID). Hardware configuration is limited to the default IP addresses. Therefore, it is generally used for bench testing.
Note: Software configurations will overwrite the hardware settings for SHR ID and for Master/Slave (see chapter 4 for software configurations). The reset button can be used to return the unit to the current hardware settings.
Hardware SHR ID Settings
Dip switches 1-7 on the rear panel of the unit are used to configure the SHR ID's. They represent bit numbers, #1, least significant and #7, most significant. The values(1, 2, 4, 8, 16, 32, and 64) for setting the SHR ID are represented by the bit number exponent of 2 (see table 1 and figure 3). Also refer to Appendix B.

Examples: To set the SHR ID
ID=1: Set dip switch 1 to the down position and the rest to the up position. ID=2: Set dip switch 2 to the down position and the rest to the up position. ID=3: Set dip switches 1 and 2 to the down position and the rest to the up position. ID=4: Set dip switch 3 to down the position and the rest to the up position. ID=5: Set dip switches 1 and 3 to the down position and the rest to the up position. ID=6: Set dip switches 2 and 3 to the down position and the rest to the up position. ID=7: Set dip switches 1, 2 and 3 to the down position and the rest to the up position. ID=8: Set dip switch 4 to the down position and the rest to the up position. ID=9 to 127: Please refer to the SHR ID Setting Tables on Appendix B.
Dip switch 8: The Slave/Master dip switch (each ring can only have 1 Master) is used to set the unit
as a Master or a Slave. Master: Set to down position. Slave: Set to up position.
Note: The Master unit must be set to SHR ID = 0 (All SHR ID dip switches must be in the up position).
When using hardware configurations, the SHR ID = N will set the IP address to 192.168.254.[100+N]. For example, if the unit is set for SHR ID = 12, the IP address is 192.168.254.112.

1. Enable the SHR dip switch on the front panel by setting it to the down position.
2. Select the fiber ports to form the SHR (set the F1/1X and F2/2X dip switches on the front panel to the up position).
3. Enable the unit to be a Slave by setting the rear panel's SLVE/MSTR dip switch to the up position.
4. Make sure that at least one SHR ID dip switch is in the down position (Slave SHR ID must be unique. See Appendix B: SHR ID Setting).
5. To ensure that hardware settings are enabled, unplug the power to the unit, press and hold the reset button on the rear of the unit, then plug in the power and release the reset button.
6. The ALARM LED will flash and the audible alarm will sound until the SHR is complete. If desired, the audible alarm can be disabled by setting the DISALM dip switch on the front panel to the down position.
7. The MSTR/SLVE LED on the front panel should be off.
Repeat steps 1-5 for the remaining slave units.
After completing the configurations for the Master and Slave units:
1. Interconnect the switches in a ring setup using the fiber ports as shown in figure 4. The SHR must be configured as a ring.
2. Connect the Fiber Ports F1 to F2 of adjacent unit (Rx to Tx and Tx to Rx) as shown in Figure 4.
The following LEDs status should be observed to verify the integrity of the units and all connections after power up and all connections have been made as in figure 4:
On the Master unit: "ALARM" LED Off, "MSTR/SLVE" LED solidly lit, "F1/1X" and "F2/2X"
LEDs solidly lit, "100M" and "FULL/COL" LEDs solidly lit, "LINK/ACT" LED solidly lit or flashing (as optical communication has been established and there is Ethernet activity), "PWRA" and/or "PRWB" LEDs solidly lit.
On the Slave units: "MSTR/SLVE" LED Off on all Slave units. All other LEDs should behave
the same way as those on the Master unit.
Note: See chapter 4 for software configurations and system monitoring.

Chapter 4 - Software Configuration
Configuring the TC3720's
Software Configurations are done through the Management port (RJ-45 connector on the rear panel of the switches).
Note: Software configurations will overwrite the current hardware settings. If changed, the hardware
settings will not reflect the current software settings.
In order to configure the TC3720's that is, set to default, the user needs to use a PC with a web browser installed. Furthermore, the PC's IP address must be set within the range of 192.168.254.1 to 192.168.254.99, and with a Network Mask of 255.255.255.0. We recommend that you set your PC within these ranges to avoid a potential conflict with the IP configuration of the TC3720's. If your PC does not have a compatible IP Address and Network Mask, or you are not sure about the settings, refer to the "PC IP Configuration" section on page 30 for more detail. You can also change the IP address of the TC3720 by matching it up with that of your PC, refer to Console Port Settings on page 26.
To configure the TC3720, simply enter the default IP address of the TC3720 in the Web browser's address box. For example, if the unit is set to Master by hardware settings, SHR ID=0, the default IP address should be 192.168.254.100.
If, for example, the unit is set to be a Slave with SHR ID=4 (with rear panel DIP switch #3 to the down position), then the default IP address should be 192.168.254.(100+4).
TC3720
Rev. 1.5
(Attention: Contact your network administrator if you are unsure about the settings. Improper settings may result in disruption of the existing network.)
Once you enter the IP address and click enter, you will see a verification window, where you will be prompted to enter a username and password:
Enter user under User Name and enter password under Password and click "OK." You will then see a window as in figure 5.
Note: The username and password can be returned to the default username and password by using the reset button (refer to rear panel diagram on figure 2). All settings will be returned to the current hardware settings.
If you would like to use the default IP addresses, see page 11 to do the configurations using the SHR ID settings.

SHR Master: Select either Master or Slave. SHR Port: This is the UDP port used by the TC3720. It can be any number as long as it is not used for public
port such as 80, 23 and etc. We recommend to use the factory default UDP port.
Note: All SHR ports of the switches on the ring should be kept the same.
SHR ID: Any integer. All units in a ring must have a unique SHR ID. SHR Master ID: All units in a ring must be set to the same SHR Master ID.
For example: The "SHR Master ID" and "SHR ID" for the Master should always be the same (by
default they should be zero "0"). The "SHR Master ID" value should also be set to zero on all Slave units in the ring to match that of the Master. If this value is changed in the Master unit, it should also be changed to the same value on all Slave units in the ring.

General
Alarm conditions occur whenever an optical problem or "fault" condition is detected by the TC3720's.
All LEDs are Off
If no LEDs are lit on the unit, check the DC power supply, terminal block connector plug, and/or the power source. If the problem persists, contact the Technical Support Department at TC Communications, Inc.
Alarm LED
When an alarm condition is detected, the ALARM LED will flash. The following fault conditions will cause the alarm to be triggered:
1. Power is lost to any unit in the SHR. This will cause adjacent units to go into alarm, indicating a fault in the SHR.
2. Fiber optic cable breakage in the SHR will also trigger an alarm condition.
Other LEDs
1. Any fiber optic cable breakage in the SHR will trigger an alarm condition between any two adjacent units as well as on the Master. Depending on which fiber port F1 or F2 the breakage occurs, the corresponding F1/1X or F2/X2 LEDs will also flash.

Rev. 1.5
Optic Cable Types
Conventionally, fiber optic cable with yellow-colored insulation is used for Single Mode applications; gray or orange-colored insulated cable is for Multimode use. If Multimode cable is used in a Single Mode application, the test results could be erroneous and confusing.
Calculating the Fiber Optic Loss Budget
The fiber optic link and/or connectors are frequently the source of various problems. Check out the connectors and the integrity of the link first. Ideally, the link should be calibrated for total loss after the installation has been completed. This will accomplish two things: (1) it will verify that the total loss of the link is within the loss budget of the device and (2) it will provide a benchmark for future testing. For example, a system that has been tested as having 6dB total loss when installed and suddenly tests out as having a loss of 10dB probably has a connector or link problem.
To calculate the loss budget:
Multimode 850nm : 3 dB loss per km on 62.5/125µm cable* Multimode 1310nm : 2 dB loss per km on 62.5/125µm cable* Single Mode 1310nm : 0.5 dB loss per km on 9/125µm cable* Single Mode 1550nm : 0.4 dB loss per km on 9/125µm cable*
*These numbers are listed for reference only. We recommend an OTDR reading be used to determine actual link loss.
