Description

Featuring distances up to 80km, the TC3715 10/100Base-T Ethernet Fiber Optic Switch provides two
100Base-FX ports that combine Ethernet Switching and Fiber Optic technology to boost total network
bandwidth.

The TC3715 provides a rate limiting feature that allows users to have control of the incoming and outgoing
data rates on both fiber ports and RJ-45 ports. The incoming data rate on both fiber ports and RJ-45 ports
can be limited to 128K, 256K, 512K, 1M, 2M, 4M, 8M, 16M, 32M, and 64M. The outgoing data rate on both
fiber ports and RJ-45 ports can be limited to 128K, 256K, 512K, 1M, 2M, 4M, and 8M.

The TC3715 offers two multimode (1300nm) or single mode (1300/1550nm) optical ports and six Ethernet
10/100Base-T Auto-Sensing/Auto-Negotiation switched ports. Each of these ports supports either 10Base­T or 100Base-TX. There are two optional versions (Model TC3715T) for extreme temperature applications
(-20C to 70C, -40C to 80C).

Because it functions like an Ethernet bridge (connects multiple Ethernet segments to prevent unnecessary
network traffic), it creates an efficient sub-divided switched LAN that provides full and transparent
bandwidth for each segment.

The TC3715’s modern switching technology eliminates the congestion problem inherent to the contention­oriented 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.
Standard power input is 12VDC, optional 24VDC, -48VDC, 125VDC, or 115/230VAC with an external
power cube. Units are standalone or 19" rack mountable. Optical connectors can be SC, ST or FC.

Power Requirements

Rev. 2.0 (A0.1)

A. The TC3715's standard input voltage is 12V DC and current is 600mA.
B. The TC3715's power connectors are two terminal blocks located on the rear panel of the unit. Polarity

is indicated on each connector block (see Figure 1).

C. Should an external power adapter need to be replaced, use one with the following specifications: 12V

DC @600mA. You may order it directly from TC Communications.

D. The TC3715 can also be ordered with an optional 24 VDC, 48 VDC or power supply. Current

consumption at 24VDC is 300mA, at 48VDC is 150mA, and at 125VDC is 60mA.

System Start Up

1. Apply the power by plugging the power plug into any power jack on the rear panel. The power source

can be from a power adapter or from a power card (installed either on the left or right side of the rack).

2. 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.

3. The "Vcc1" and "Vcc2" LEDs should also light, indicating an adequate operating voltage is being derived

from the power source.

4. Connect the twisted pair cables to the RJ-45 connectors on the front panel of the switches. If the twisted

pair cables are providing an Ethernet signal, then the corresponding front LEDs for that particular
channel will light as follows:

a). If the user's device is in auto-negotiation mode and 100Mbps full duplex is detected by the switch,
the 100M & FULL/COL LEDs will be solidly lit and the LINK/ACT will blink as activity is detected.

b). If the user's device is in a dedicated mode and 100Mbps full duplex or half duplex is detected by
the switch, the 100M LED will be solidly lit and the FULL/COL and LINK/ACT LEDs will blink
as activity is detected.

c). If 10Mbps full or half duplex is detected by the switch, the 100M LED will be "Off" and the FULL/
COL and LINK/ACT LEDs will be blinking.

d). If half duplex and collisions are detected by the switch, the FULL/COL LED will be blinking.

5. Connect the optical fibers from the Tx connector of one unit to the Rx connector of the second unit, the

LINK/ACT LED of the fiber port on the second unit will be solidly lit. Do the same for the second pair
of Rx to Tx connectors and observed the LINK/ACT LED on the first unit will be lit.

7. When communication is established and traffic passes through the fiber between two TC3715's the

LINK/ACT LED will blink.

Dry Contact Relay Alarm

Two terminal block connectors on the rear panel (labeled
"ALARM RLY1," & "ALARM RLY2") provide for the dry
contact relay alarm (see Figure 1). 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.

Dry Contact Alarm Condition:

When the front panel LINK/ACT LED is lit and/or blinking, the TC3715 is working well and thus it is not
in Alarm Condition. Otherwise, if the LINK/ACT LED is "Off" the TC3715 will be in Alarm Condition and
the Dry Contact Relay will be activated.

Chapter 2 - Hardware Configuration

SHR ID Setting (Default IP Setting)
The TC3715s can be connected with a maximum of 128 units. The IP address can be configured with either

hardware or software (each unit must have a unique IP). 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 IP Address. 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 TC3715 IP Address. They represent
bit numbers, #1, least significant and #7, most significant. The values(1, 2, 4, 8, 16, 32, and 64) for setting
the IP Address are represented by the bit number exponent of 2 (see table 1 and figure 3). Also refer to
Appendix B.

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.
Note: The SLVE/MSTR Dip switch is Not Used.

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.

Configuring the Alarm Dip Switches (Front Panel):

1. SHR Dip Switch: Not used. Always keep the SHR dip switch in the down "Off" position.

2. DISALM Dip Switch: This is the master alarm dip switch used to enable/disable the entire TC3715’s
Alarm Buzzer and Dry Contact Relay Alarm for the fiber ports. To enable the alarm, put the dip switch in
the up "On" position. To disable the alarm, put the dip switch in the down "Off" position. The "DISALM"
dip switch must be enabled for the F1/1X and F2/2X dip switches to function properly.

3. F1/1X Dip Switch: This dip switch enables/disables just Fiber Port F1’s alarm. To enable F1’s alarm,
put the dip switch in the up "On" position. To disable F1’s alarm, put the dip switch in the down "Off" position.

4. F2/2X Dip Switch: This dip switch enables/disables just Fiber Port F2’s alarm. To enable F2’s alarm,
put the dip switch in the up "On" position. To disable F2’s alarm, put the dip switch in the down "Off" position.

When either fiber port signal is disconnected, the TC3715 alarms will be triggered: the Alarm LED will flash,
the alarm buzzer will sound, and the dry contact alarm will be forced to the close position. One example,
assume all alarm dip switches are enabled. If the user only wants to use F1 Fiber of the TC3715, then the
lack of a signal for F2 Fiber will cause the alarms to sound. In order to avoid this case, position the F2/2X
dip switch to the down position to disable it. This will prevent F2 from triggering the alarm.

Chapter 5 - Troubleshooting

PC Configuration:

In order to communicate with a TC3715 that is set to default, the user’s PC IP address must be set within
the range of 192.168.254.1 to 192.168.254.254, with a Network Mask of 255.255.255.0. To check your PC's
IP Address and Network Mask. (Windows 98/ME)

1. Open “Control Panel”

2. Open “Network”

3. Click on the TCP/IP for the network card

4. Click “Properties”
If your PC has a compatible IP Address and Network Mask. Please go to the Web-based Interface section.

(Attention: Please copy down the existing setting before making any changes. Contact your local network
administrator if you are unsure about the settings. Improper settings may result in disruption of the current
network.)

Under the TCP/IP Properties
Select the “Specify an IP address” option and type in the following
IP Address: 192.168.254.1 (Please make sure no other network device are using the same IP address.)
Subnet Mask: 255.255.255.0
Click OK and reboot the computer.

Troubleshooting Continue

Power Problem:

No LEDs are lit:

A. "PWRA" and/or "PWRB" LEDs should be on when power is connected. If both are "Off," then no DC

power is reaching the unit. Check the power supply, source, and polarity.

B. If "PWRA" and/or "PWRB" LEDs are "On" but all other LEDs are "Off", and the Alarm switch is not

closed, it indicates an internal problem with the unit. For assistance, please contact the Technical Support
Department at TC Communications @ [phone].

Electrical Problem:

If All LEDs, 100M, FULL/COL, and LINK/ACT, are OFF:

It means that there is no ethernet electrical signal detected by the TC3715. Check the twisted pair cables
for good connectivity. Make sure that the units have adequate power.

Optical Problem:

If the 100M and FULL/COL LEDs are lit, and the LINK/ACT LED is OFF:

A. Check the physical fiber optic cable connection to make sure it is not loose or broken.
B. Optic "Tx" is connected wrongly to another TC3715's "Tx."
C. Optic cable type is incorrect. Typically, fiber optic cable with yellow-colored insulation is designated for

Single Mode use @8.2µm or 9µm; orange or gray-colored cable is for Multimode use @50µm or 62µm.
If the wrong cable type is used, the unit will not function properly.
