TC3720
User's Manual
Rev. 1.5
Installation Procedure Summary (Continue)
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.
